A hafnium silicide strength has high melting points, high corrosion resistances, high oxidation resistant, and is good for electrical installations.
Hafnium Silicide Puffer Characteristics
Hafnium Silicide is considered a Transition Metal Silicide. It is also a type or refractory-intermetallic compound. Because of its unique physical and chemical properties, it has been successfully used in complementary metal-oxide-semiconductor components, thin-film coatings, bulk structure components, electric heating Components, thermoelectric materials and photovoltaic materials. You could use it in catalysis because of its unique electrical, optical magnetic, thermoelectric and magnet properties. Unfortunately, conventional preparation methods (metallurgical techniques or physical) are not sufficient to produce transition metal silicide nanomaterials. The solution to the problem of transitional metal silicide nanomaterials is simple, easy and controllable.

Hafnium Silicon: Application
1. Preparation of an ablative composite layer of silicon carbide/hafnium/tantalum silicide (SiC_HfSi2-TaSi2). A carbon fiber reinforced material (C/C), a high temperature-resistant composite material that uses silicon carbide-hafnium silicide and tantalum silicide (SiC–HfSi2-TaSi2) as the reinforcement. The matrix is carbon fiber with pyrolytic carbon. In the early 1970s the United States conducted research into C / / composite materials for thermal structure development. You can use C / c composite materials as structural, thermal materials in the gas turbine engine, space shuttle nose cone caps, and wing leading edges. They are able to work in extreme temperatures or oxidation conditions.
Unfortunately, C / c composites can be easily oxidized. For C / F composite materials to be protected against oxidation, it is crucial that anti-oxidation protective coatings are prepared. Refractory metals Zr (Hf), Ta (TiB2), etc. have been shown to improve the ablation resistance of C /C composites. When refractory elements Zr and Hf are added to the carbon matrix the composites’ ability to resist ablation can be improved. In an attempt to better understand the impact of metal Hf or Ta on the ablation efficiency of C /C Composites, several experiments used SiC–HfSi2–TaSi2 anticoagulation coatings. This anti-ablation coating was prepared using the embedding method. Knot
2. Prepare an organic electric luminescent device. This package includes an anode (light-emitting), a cathode and a cover. They are sequentially placed. The package cover protects both the light emitting layer and the cathode of the anode. The package cover contains a silicon-carbonitride coating and a barrier. The silicide layer is made from silicide or a metal dioxide. The metal oxide can be selected from magnesium oxide (or aluminium oxide), titanium dioxide, zirconium dioxide, hafnium dioxide, and tantalum pentoxide. The life expectancy of the above mentioned organic electroluminescent gadget is very high. It also includes a procedure for creating an organic electronic electroluminescent.
3. Prepare a thermoelectric element made from silicon-germanium alloy. The silicon and germanium alloy based thermoelectric element includes an electrode layer, a silicon and-germanium alloy-based temperatureelectric layer, as well as a barrier layer that is between the silicon and-germanium mixture-based layer. The silicon-germanium alloy-based thermoelectric element is composed of an electrode layer, a silicon-germanium alloy -based thermoelectric layer and a barrier layer between the electrode layers. Silicide is at minimum one of molybdenum or tungsten silicide, cobalt silicide, nickel silicide and cobalt silicide. The interfaces of the silicon-germanium alloy-based thermoelectric device are well mixed, with no apparent diffusion phenomena and cracks. They also have a good thermal contact status and are able to withstand an extended high-temperature fast test. This preparation technique is also simple and easy to follow, with low costs, reliability, minimal equipment required, making it suitable for mass production.
4. Preparation of a high temperature and oxidation resistance cermet-composite coating. The composition of the composite film includes refractory materials, refractory carides, intermetallic compounds and silicon carbide.
