What is Hafnium Diicide HfSi2? Hafnium desilicide The molecular formula Hafnium silicide has the molecular mass of 234.66. It is gray powder.
Hafnium silicide, a type a transition metal silicide as well as a class of refractory intermediatemetallic compounds. A unique combination of chemical and physical properties makes hafnium silicide a highly effective choice in fields such as bulk structural components and semiconductor components, thin films coatings, photovoltaic materials, and thermoelectric materials.
Hafnium-disilicide nanomaterials exhibit special electrical and optical properties. They could also be useful in catalysis.

What is Hafnium Diilicide HfSi2 Used for?
1. To prepare silicon carbide-hafnium silicide-tantalum silicide (SiC-HfSi2-TaSi2) anti-ablation composite coating
Carbon fiber reinforced carbon (Chand C), composite is a novel type of high temperature composite that uses carbon fiber reinforcement and pyrolyticcarbon as a matrix. The composite’s excellent properties at high temperatures, ablation resistance, good friction and wear characteristics led to research by the United States on Chammer C composites for thermal structures. This work resulted in the creation of Cmax C Composites from cauterized heat-proof material to thermal structure materials. C/C can be used as a thermal structure material in components for gas turbine engines, spacecraft nose cone cap, wing lead edge, and many other places. Many of these parts are designed to work in extreme temperatures and oxidation conditions.

CPAC composites, however, are very easy to oxidize. They will usually not function normally in an oxygen atmosphere higher than 400. Chammer C composites need to be properly protected from oxidation. The preparation of an anti-oxidation coat is one of the most important protective measures. The results indicate that C / C composites have a higher ablation rate when additional refractory materials Zr, Hf and Ta are added to their carbon matrix. To understand the influence of Hf,Ta on Chand-C composites’ ablation performance, SiC–HfSi2-TaSi2 antiablation coated was prepared by embedding. Oxyacetylene ablation devices were used to measure the coating’s ablation performance. Knot.

2. To create organic light-emitting gadgets
The package cover covers the light emitting layers and the cathode on anodes. A silicon carbonitride-based layer is used as a barrier to protect the silicon carbonitride. The barrier layer contains silicide as well as metal oxides. At least one is chromium, tantalum, hafnium, titanium, molybdenum, and tungsten silicide. The metal dioxide can be chosen from magnesium oxide and aluminum trioxide, zirconium dioxide, hafnium dioxide, tantalum pentoxide, hafnium oxide, and tantalum pentoxide. The organic light-emitting device mentioned above has a longer life span.

3. To make silicon-germanium-alloy-based thermoelectric components
The silicon-germanium alloy-based, silicon-germanium thermoelectric element is made up of an electrode, a silicon germanium alloy-based thermal layer and a barrier layer. This layer acts as a buffer between the silicon-germanium layer and the silicon germanium mixture-based temperatureelectric layer. The barrier layer is made up of silicide as well as silicon nitride. The silicide contains at least one silicide from each of the following: molybdenum silicide tungsten silicide cobalt silicide nickel silicide zirconium silicide tantalum silicide and hafnium silicide. The interface of silicon-germanium alloy based thermoelectric element has a well-bonded structure. It is resistant to cracks and diffusion phenomena, can withstand high temperature accelerated testing for a long time, and is thermally stable.

4. To prepare the cermet coating with high temperature resistance, oxidation resistance, and other properties.
The composite film has a thickness of 10 mm x 50 mm. The refractory metallic is one of molybdenum or tantalum or zirconium. The intermetallic compound is one of molybdenum or tantalum silicides or zirconium carosilicides as well as tantalum silicide or zirconium carosilicide. The crystal structure of the coating is made of amorphous, / or polycrystalline microparticles.
