A hafnium silicide strength has high melting points, high corrosion resistance, strong oxidation resistance, and excellent electrical capabilities.
Hafnium Silicide Puffer Characteristics
Hafnium Silicide can be described as a Transition Metal Silicide. This is an intermetallic, refractory 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 and optical properties. Unfortunately, conventional preparation methods (metallurgical techniques or physical) are not sufficient to produce transition metal silicide-like 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 ortantalum-silicide (SiC–HfSi2-TaSi2). Carbon fiber reinforced carbon (C/C), a type of new composite material that resists high temperatures, uses carbon fiber as the reinforcement. The matrix is made from pyrolytic carbon. In the early 1970s the United States conducted research into C /C materials for thermal structures. 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-composite materials are easy to oxidize and can’t be kept in an atmosphere that exceeds 400 degrees Fahrenheit. For C / D composites materials this means that they need to be protected against oxidation. The best protection measures are anti-oxidation coated. Refractory metals Zr and Hf can be added to carbon composites. When refractory elements Zr and Hf, as well as TiB2, Ta, and Ta are mixed into the carbon matrix it is possible to increase the composite’s ablation resistance. It is possible to study the impact of metal Hf or Ta on the ablation resistance of C /C Composites. Some experiments involved the preparation of SiC–HfSi2–TaSi2 ano-ablation coatings using the embedding process. Knot
2. Prepare an organic electric luminescent device. This package includes an anode (light-emitting), a cathode (cathode), and a package covering that is sequentially stacked. The package cover protects both the light-emitting material and the anode’s cathode. 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, hafnium dioxide, zirconium dioxide, hafnium pentoxide, and titanium silicide. The organic electroluminescent devices mentioned above have a very long lifespan. It also includes a procedure for making an organic electronic electroluminescent.
3. Prepare a thermoelectric element made from silicon-germanium alloy. The silicon-germanium alloy-based silicon thermoelectric element consists of an electrode layer as well as a silicon beryllium alloy thermoelectric 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 one or more of molybdenum silicide tungsten silicide cobalt silicide nickel silicide niobium silicide zirconium, tantalum silicide and hafnium. The interfaces of the silicon-germanium alloy-based thermoelectric elements are very well combined. They have no apparent diffusion phenomena and cracks, their contact resistance and thermal state are excellent, and they can 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 resistant, oxidation resistive cermet compound coating. The composition of the composite film includes refractory materials, refractory carides, intermetallic compounds and silicon carbide.
