What is Hafnium Disilicide HfSi2?

Hafnium disilicide or hafnium silicide with the molecular formula HfSi2 has the molecular weight of 234.66. It is gray powder.

Hafnium disilicide is a type of change steel silicide and a kind of refractory intermetallic substances. Because of its one-of-a-kind physical as well as chemical properties, hafnium disilicide has actually been effectively utilized in the fields of corresponding metal oxide semiconductor elements, thin film finishings, bulk structural elements, electrothermal elements, thermoelectric materials, and also photovoltaic products.

Hafnium disilicide nanomaterials reveal special electrical, optical, magnetic and thermoelectric residential or commercial properties, and also even have prospective applications in the field of catalysis.

What is Hafnium Disilicide HfSi2 Used For?

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

Carbon fiber reinforced carbon (Chand C) compound is a brand-new sort of high temperature immune composite with carbon fiber as support and also pyrolytic carbon as matrix. As a result of its superb high temperature strength, ablation resistance and great friction and use homes, in the very early 1970s, the United States carried out the study job of Chammer C composites for thermal framework, which led to the growth of Cmax C composites from cauterized heat-proof products to thermal framework products. As a thermal architectural material, C/C composite can be made use of in gas wind turbine engine elements, space capsule nose cone cap, wing leading edge and so on. The majority of these components work in heat and oxidation atmosphere.

Nevertheless, CPAC composites are easy to oxidize as well as normally can not work generally in an oxidation ambience above 400 ℃. This needs correct anti-oxidation protection of Chammer-C composites, and the prep work of anti-oxidation coating is one of the primary protective measures. The results show that when refractory steel Zr, Hf, Ta, TiB2 and other refractory metals are contributed to the carbon matrix, the ablation resistance of C/ C compounds can be better boosted. In order to understand the impact of metal Hf, Ta on the ablation efficiency of Chand-C compounds, the SiC-HfSi2-TaSi2 anti-ablation finishing was prepared by embedding technique, as well as the ablation efficiency of the anti-ablation layer was gauged by oxyacetylene ablation gadget. Knot.

2. To prepare organic light-emitting devices

The bundle cover encapsulates the light releasing layer as well as the cathode on the anode, and also the plan cover consists of a silicon carbonitride layer and also a barrier layer formed on the surface of the silicon carbonitride layer. The product of the barrier layer makes up silicide as well as steel oxides selected from at the very least among chromium silicide, tantalum disilicide, hafnium silicide, titanium disilicide, molybdenum disilicide and tungsten disilicide, and also the steel oxide is selected from magnesium oxide, aluminum trioxide, titanium dioxide, zirconium oxide, hafnium dioxide as well as tantalum pentoxide. The life time of the above organic light-emitting gadgets is longer.

3. To prepare silicon-germanium alloy-based thermoelectric aspects

The silicon-germanium alloy-based thermoelectric component is made up of an electrode layer, a silicon-germanium alloy-based thermoelectric layer as well as an obstacle layer between the electrode layer as well as the silicon-germanium alloy-based thermoelectric layer. The barrier layer is a mix of silicide as well as silicon nitride. The silicide is at least among molybdenum silicide, tungsten silicide, cobalt silicide, nickel silicide, niobium silicide, zirconium silicide, tantalum silicide as well as hafnium silicide. The interface of the silicon-germanium alloy-based thermoelectric element is well bonded, there is no split and apparent diffusion phenomenon at the interface, the call resistance is reduced, the thermal call state is good, as well as can stand up to heat sped up test for a long time.

4. To prepare the cermet composite finishing with high temperature resistance and also oxidation resistance

The composite film is characterized because the finishing is made up of refractory metal, refractory carbide as well as intermetallic substance, as well as the thickness of the finishing is 10μm ~ 50μm. The refractory metal is several of molybdenum, tantalum, zirconium as well as hafnium; the refractory carbide is composed of silicon carbide and also one or more of tantalum carbide, zirconium carbide and hafnium carbide; the intermetallic compound is several of molybdenum silicide, tantalum silicide, zirconium silicide, tantalum carbosilicide, zirconium carbosilicide and also hafnium silicide. The crystal structure of the covering is composed of amorphous as well as/ or polycrystalline nanoparticles.
