Hafnium was used as a metal crucial in the application of the industries, like nuclear energy and aerospace sector. It is a silver-gray, shiny metal usually used as alloy in nuclear science. The supply of the material is not at all limited. It is available in abundant quantity in the Earth's crust. The material is never a rare metal, even in supply it is there more than that of silver, gold, germanium,molybdenum metalandtantalum metal. However it is only produced in quite a very small amount of quantity such as approximately 70 tons a year. There are two reasons for the fact. Firstly the application of Hafnium is limited to as a byproduct for refining zirconium for nuclear-related applications. And secondly, the cumbersome production procedure of the metal, as it is very difficult to separate Hafnium from zirconium. Hafnium metalis a ductile, shiny metal about two times more dense than zirconium. The production process of hafnium is never so easy. It has to go through a much extended and complex refining process. That is the reason why you find only two significant producers of Hafnium all through the worldwide. Many researchers say that, hafnium is present in zirconium at a ratio of around 1:50.The chief source of supply of hafnium metal is the zircon a product of zirconium. Recently hafnium has been using for three main segments firstly as super alloys for the application of both aerospace and non-aerospace product, secondly as refractory metal alloys and lastly for nuclear applications. It is used in polycrystalline nickel-based super alloys as well as high-temperature alloys. The melting point of hafnium is very high 2,233°C (4,051°F); this helps strengthen the other material like carbon, oxygen and nitrogen. However as the material is very strong and can cope with high temperatures and pressure, it is most commonly used turbine blades and vanes of jet engines. Thepurified zirconiumcontains only two percent of hafnium metal, which is the only source of hafnium supply. Thus the metal is very costly though not very rare. But the advent of technique makes the alternate uses of the metal possible in different segment. This increased the price of the metal with an increase in demand for the metal. But the supply of hafnium still depends on the use of zirconium. Apart from the industrial world it is also helpful for the tech world in the production of electronic items. Hafnium oxide is useful for the mechanism of blue lasers in DVD readers. It is often used in optical applications to provide hardness and protection through a thin film coating.

Platinum is an amazingly uncommon metal, happening as just 0.003 ppb in the Earth's outside, and is 30 times rarer than gold. In the event that all the world's platinum stores were put into one Olympic-size swimming pool, it would be sufficiently profound to blanket one's lower legs. Gold would fill more than three such pools. In 2006, the world supply of Platinum was about 217,700 kg, or 7 million Troy ounces. In 2007, worldwide supplies of 6.5 million ounces were more than matched by the interest of 7.03 Million ounces. It is utilized within the accompanying commercial ventures and also others: * As an impetus in the exhaust system, a discretionary (however frequently obligatory by law) segment of the gas energized auto debilitate framework (see "Outstanding aspects" in this article). * As an impetus in power modules. Diminishing the measure of platinum obliged (and hence cost) is a real center of power module research. * Certain platinum holding mixes are equipped for crosslinking DNA and murder cells by comparative pathways to alkylating chemotherapeutic operators. Cisplatin, carboplatin and oxaliplatin are authorized illustrations of this class of medications. * Platinum safety thermometers. * Electrodes for utilization in electrolysis and electrochemical estimations (e.g. the standard hydrogen anode). * In the Clark polarographic anode for measuring oxygen pressure. An extensive variety of gems. * As an impetus in the curing of silicone elastomers. * As an impetus in gleam connects to some model motors. * In pots, alloyed with rhodium (10-40% of Rh), for high temp dissolving around 1500° C of glass. * In photography, it is once in a while utilized for archival printmaking. Platinum prints show a more prominent extent of tones than other Black and White printing strategies. Moreover platinum's substance strength makes for amazingly dependable prints. The issue with this technique, notwithstanding the high cost, is that platinum is less light delicate and prints must be contact printed at the same size as the negative. Hence, amplifications must be made by making a developed negative.Platinum cruciblesalts alone for the most part make inordinate difference in prints; joined together with salts from its sister metal, palladium, produce hotter and gentler tones, without lessening the tonal reach platinum empowers. * In watchmaking, Vacheron Constantin, Patek Philippe, Rolex, Breitling and different organizations use platinum for creating their restricted release watch arrangement. Watchmakers exceptionally like the novel properties of platinum as it not stains or wears out.

At present, most of the thermal conductive materials used in the field of silicone are alumina, silicon oxide, zinc oxide, aluminum nitride, boron nitride, silicon carbide and so on. In particular, micron alumina and silicon powder are the main body, nano-alumina and nitride are used as filler powder in the field of high thermal conductivity, while zinc oxide is mostly used as filler of thermal conductive silicone grease. Characteristic analysis: 1.Aluminum NitrideAlN Advantages: The thermal conductivity is very high. Disadvantages: expensive, usually more than 1000 yuan per kilogram; AlN + 3H 2= Al (OH) 3 + NH 3 will be hydrolyzed by water after moisture absorption, and Al (OH) 3 produced by hydrolysis will interrupt the thermal conduction pathway, thereby affecting phonon transfer, so the thermal conductivity of the product is low. Even if silane coupling agent is used for surface treatment, 100% of the filler surface can not be guaranteed to be coated. Aluminum nitride alone can achieve high thermal conductivity, but the viscosity of the system increases greatly, which seriously limits the application of the product. 2.Boron nitrideBN Advantages: The thermal conductivity is very high and the property is stable. Disadvantages: high price, market price from hundreds to thousands of yuan (according to the product quality difference is large). Although the use of boron nitride can achieve higher thermal conductivity, but ｉｔ ｉｓ similar to aluminum nitride, the system viscosity increases greatly after a large number of filling, which severely limits the application of products. 3.Silicon CarbideSiC Advantages: High thermal conductivity. Disadvantages: Carbon and graphite produced in the synthesis process are difficult to remove, resulting in low purity and high conductivity of the product, which is not suitable for electronic adhesives. Because of its high density, it is easy to precipitate and stratify in organic silica gels, which affects the application of products. Epoxy resin is more suitable. 4.Magnesium oxideMgO Advantages: Low price. Disadvantages: It is easy to absorb moisture in the air, has strong viscosity, and can not be filled in large quantities; it has poor acid resistance and is easily corroded by acid in general, which limits its application in acidic environment. 5.Alumina(acicular) Advantages: Low price. Disadvantage: Low addition, in liquid silica gel, the maximum addition of ordinary needle alumina is generally about 300 phr, resulting in limited thermal conductivity of the product. 6. Alumina (spherical) Advantages: Large filling capacity, in liquid silica gel, spherical alumina can be added to 600 ~ 800 parts, resulting in high thermal conductivity products. Disadvantage: The price is more expensive, but lower than boron nitride and aluminum nitride. 7.Zinc oxide Advantages: Good particle size and uniformity, suitable for the production of thermal conductive silicone grease. Disadvantages: low thermal conductivity, not suitable for the production of high thermal conductivity products; light weight, strong viscosity, not suitable for filling. 8. Quartz Powder (Crystalline) Advantages: high density, suitable for filling; low price, suitable for a large number of filling, low cost. Disadvantage: Low thermal conductivity, not suitable for the production of high thermal conductivity products. High density may result in stratification. To sum up, different fillers have their own characteristics. When choosing fillers, we should make full use of the advantages of each filler, use several fillers to mix and play a synergistic role, which can not only achieve high thermal conductivity, but also effectively reduce the cost, while ensuring the miscibility of fillers and organic silicon matrix. ...read more
