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 silicide is a type intermetallic compound that is refractory and also a transition metal silicide. Hafnium disilicide’s distinct physical and chemical characteristics have been well-received in the areas of the bulk structural components of semiconductor components, metal bulk components as well as thermoelectric materials.

Nanomaterials made from hafnium disilicide possess unique electrical, optical and magnetic properties. They could even be used for 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 an innovative high temperature resistant composite with carbon fiber as reinforcement, and carbon pyrolytic as a matrix. The 1970s were when researchers from the United States conducted research on Chammer C carbon composites for thermal structuring. This resulted in the creation of Cmax C composites. As a thermal structural material, C/C composite can be utilized in gas turbine engine components, the nose cone of spacecraft’s nose caps, wing leading edge and more. These parts are designed to work in extreme temperatures and oxidation conditions.

CPAC composites can oxidize rapidly and are unable to perform in an oxidation environment exceeding 400. Chammer-C composites must be protected from oxidation. This is why anti-oxidation coatings are necessary. The findings of this study show that C / C composites can be even more effective in ablation resistance when they are filled with refractory metallic Zr., Hf. Ta. TiB2 and other reactive metals. To determine the impact of metal Hf,Ta on the ablation efficiency of Chand-C composites, the SiC-HfSi2-TaSi2 anti-ablation layer was using an embedding technique and the ablation efficiency of the anti-ablation coating was measured by oxyacetylene ablation device. Knot.

2. To prepare organic light emitting devices.

The package cover encapsulates the light-emitting layer as well as the cathode on the anode. The package cover comprises a silicon carbonitride layer and an insulating layer that is formed over the silicon carbonitride surface. The barrier layer is made consisting of silicide and other metals. It is possible to select from at least one of the following: tantalum silicide; hafnium disilicide, molybdenum silicide; chromium silicide; tungsten disilicide. The metal oxide may be chosen from titanium trioxide or aluminum dioxide. The lifetime of the above organic light-emitting devices is greater.

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

The silicon-germanium alloy-based thermoelectric element consists of an electrode, an silicon germanium alloy-based thermal layer, and a barrier layer. This layer acts as a buffer between silicon germanium layer and the silicon germanium layer. The barrier layer consists of silicide that is mixed with silicon nitride. The silicide is at minimum one of the silicides: molybdenum tungsten silicide tungsten tungsten silicide cobalt tungsten nickel silicide niobium silicide zirconium, tantalum ilicide and hafnium siliicide. The interface of the silicon–germanium alloy-based thermoelectric elements is well bonded. There isn’t any apparent diffusion or crack at the interface. The thermal contact state is excellent and can withstand high temperatures accelerated tests for a long time.

4. To prepare the cermet composite coating with high temperature resistance as well as resistance to oxidation

The composite film is characterized by the fact that it is made up of refractory material, carbide, and intermetallic compound and the thickness of the coating is 10mm ~ 50mm. The refractory is a more than molybdenum (tantalum) zirconium (zirconium) and hafnium. The silicon carbide is made up mainly of silicon carbide, but it also contains zirconium carbide and tantalum silicide, or zirconium carbide. Intermetallic compounds include one or both of molybdenum silicides, tantalum silicides or zirconium silicide or zirconium silicide or zirconium silicide or zi silicide or hafnium silicide or silicide or silicide or hafnium silicide or zironium carbosilicide, hafnium silicide or zirconium silicidesilicidesilicidesilicide or molybdenum alum silicide molybdenum refractory and tantalum silicide The coating’s crystal structure is composed of amorphous or polycrystalline nanoparticles.
