What is Hafnium Disilicide HfSi2?


Hafnium silicide, or hafnium diilicide has a molecular weight 234.66. It is a gray powder.


Hafnium silicide is a intermetallic compound that is refractory and also a transition metal silicide. Unique combination of chemical and physical properties makes hafnium silicide an extremely effective option for applications such as semiconductors and bulk structural components made from oxides of complementary metals.


Hafnium-disilicide nanomaterials have unique electrical, optical magnetic, thermoelectric, and properties. This makes them suitable for use in catalysis.




What is Hafnium disilicide HfSi2 employed for?


1. To prepare silicon carbide-hafnium silicide-tantalum silicide (SiC-HfSi2-TaSi2) anti-ablation composite coating


Carbon fiber reinforced composite (Chand C), is a brand new type of composite that is made from carbon fiber and pyrolytical carbon as the matrix. Due to its superior ablation resistance and good friction and wear characteristics, in the early 1970s, researchers in the United States carried out the research work of Chammer C composites for thermal structure. This led to the development of Cmax C composites from cauterized heat-proof materials to thermal structure materials. As a structural material for thermal use C/C composite is used in gas turbine engine components as well as the nose cone of spacecraft’s nose cap, wing leading edge and more. These parts can be used in high-temperature and oxidation environments.




CPAC composites However, they are easy to oxidize. They are not able to perform normally in an oxygen atmosphere higher than 400. Chammer C composites require proper antioxidation protection. To protect the composites from oxidation, anti-oxidation coatings must be developed. These results showed that C/C composites’ ablation resistance can be improved by adding refractory metal Zr. Hf. Ta. TiB2 and other refractory elements to the carbon matrix. To understand the influence of Hf,Ta’s influence on Chand-C composites’ ablation performance, SiC–HfSi2-TaSi2 anti ablation coatings were made by embedding. Oxyacetylene ablation instruments evaluated the coating’s ablation efficiency. Knot.




2. To create organic light-emitting gadgets


The covers of the package contain light emitting and cathode layers that are on the anode. In addition, the cover includes a silicon carbitride coating as well as an additional barrier layer over of the silicon carbonitride. The barrier layer is made consisting of silicide and other metals. It is possible to select from any of the above: tantalum silicide hafnium disilicide, molybdenum silicide; chromium silicide and disilicide tungsten. The metal oxide may be selected from aluminum trioxide and titanium dioxide. Organic light emitting devices mentioned previously have a greater lifetime.




3. In order to make thermoelectric silicon-germanium alloy elements


The thermoelectric element made of silicon-germanium alloy is composed of an electrode layer, a silicon-germanium alloy thermoelectric layer, and an intermediate layer that is between the electrode layer and the silicon-germanium alloy thermoelectric layer. The barrier layer consists of silicide mixed with silicon nitride. A minimum of one silicide of molybdenum or tungsten silicides as well as cobalt silicides and nickel silicides is employed. The silicon/germanium alloy’s interface thermal element is solidly bonded. There isn’t any fracture or visible diffusion phenomenon at the surface.




4. To prepare an acetylene composite which is resistant to extreme temperatures and oxidation.


The film composite is distinguished by its being composed of refractory material refractory carbonide, and intermetallic substances. The coating’s thickness is 10mm x 50mm. The refractory metal comprises at least one of molybdenum, zirconium, tantalum and hafnium; the refractory carbide is composed of silicon carbide and some or all of tantalum carbide, zirconium carbide, and hafnium carbide. The intermetallic compound is made up of one or more of molybdenum silicide, tantalum silicide, zirconium silicide, tantalum carbosilicide, zirconium carbosilicide and hafnium silicide. The crystal structure of the coating is composed of amorphous and or polycrystalline microparticles.
