Overview of silicide H HfSi2 powder:

Hafnium silicide is a transition metal silicide, a refractory intermetallic compound.

Due to its unique physical and chemical properties, hafnium silicide has been successfully used in CMOS devices, film coatings, box structure parts, electric heating elements, thermoelectric materials and photovoltaic materials, etc.

In addition, hafnium silicide nanomaterials have special electrical, optical, magnetic and thermoelectric properties, which have potential application value in the field of catalysis.

Our silicide ha products have the characteristics of high purity, small particle size, uniform distribution, large specific surface area and high surface activity.

Silicidation is most commonly used in ceramic materials to manufacture various high-temperature-resistant parts and functional parts.

Its nanomaterials show special electrical, optical, magnetic and thermoelectric properties, and even have potential application value in the field of catalysis. However, traditional preparation methods such as metallurgical methods or physical methods cannot satisfy the preparation of transition metal silicide nanomaterials. Therefore, finding a simple, controllable and universally applicable preparation method is of great significance for the wide application of transition metal silicide nanomaterials.

1. Preparation of silicon carbide-hafnium silicide-tantalum silicide (SiC-HfSi2-TaSi2) anti-ablation composite coating. Carbon fiber reinforced carbon (C/C) composite material is a new type of high temperature resistant composite material with carbon fiber as the reinforcement and pyrolytic carbon as the matrix. Because of its excellent high-temperature strength, ablation resistance and good friction and wear properties, the United States carried out research work on C/C composite materials for thermal structures in the early 1970s, and changed C/C composite materials from burning and heat-resistant materials to Development of thermal structural materials. C/C composite materials can be used as thermal structural materials for gas turbine engine structural components, space shuttle nose cone caps, wing leading edges, etc. Most of these components work under high temperature and oxidation environments.

However, C/C composite materials are easily oxidized, and usually cannot be serviced in an oxidizing atmosphere higher than 400 ℃. This requires proper anti-oxidation protection for C/C composite materials, and the preparation of anti-oxidation coatings is one of the main protective measures. Studies have shown that when refractory metals Zr, Hf, Ta, TiB2, etc. are added to the carbon matrix, the ablation resistance of C/C composites can be further improved. In order to understand the influence of metal Hf and Ta on the ablation performance of C/C composites, some experiments have used the embedding method to prepare SiC–HfSi2–TaSi2 anti-ablation coatings. The anti-ablation coatings were measured with an oxyacetylene ablation device. Ablation performance of the layer. Knot
