What is it?

Tantalum Carbide


Tantalum carbide is a light-brown metallic cubic crystal powder that belongs to the sodium chloride type cubic crystalline system. Tantalum carbid can also be used as a cemented-carbid sintered grain growth inhibiter. The density of the powder is 14.3g/cm3. Insoluble in water, insoluble with inorganic acid, soluble and decomposed in mixed acid of hydrofluoric and nitric acids. It has strong antioxidant properties and can be easily melted and broken down by potassium pyrosulfate. Superior conductivity and resistance to 30O at room temperature, with superconducting characteristics. Powder metallurgy, fine ceramics and chemical vapor deposition are all used. The tantalum carbide sintered body can be used to make watch decorations. It is also available in golden yellow.

Tantalum Carbide’s main features

Ceramic particles of Tantalum carbide ceramic (TaC), possess the following advantages: high melting point (3880degC), high strength (2100HV0.05), chemical stability, high electrical and thermal conductivity, as well as high hardness (2100HV0.05). Aluminum base and other substrates. Chao et al. The laser cladding technique was used to create a nickel-based reinforced tandemlum carbide surface composite material. Yu et.al. showed that the material’s hardness is significantly higher than that of pure nickel. The wear rate is also significantly lower than that for hardened steel. The relationship between in situ reaction directional solidification tantalum carbonide enhanced with base, chromium and aluminum bases and its microstructure. The results reveal that as solidification rates increase, so does the solid phase structure. Additionally, the volume fractions of tantalum carbohydrateside change with solidification rates. Wang Wenli et al. The laser cladding technique was used to prepare an in-situ TaC alloy-enhanced nickel-based coating on A3-steel. Smooth surface with a strong metallurgical connection between the substrate and the coating. Unfortunately, very few reports have been made about the in-situ generation of TaC from steel substrates. In this experiment, we used the surface ceramic particle reinforced iron matrix composite. TaC particles are used as reinforcement particles for the second phase. Analyses were made of the micromorphology and reaction processes of TaC particles, in-situ reinforced iron based surface composites.

Tantalum Carbide has many applications

1. Cemented carbide is used a lot as an additive. Its primary function is to improve the high-temperature strength of cemented carbide and inhibit the growth tungsten carbide particles.

2. Use it as a hard coat to protect the base metal from chemical corrosion and wear.

3. It is used by the military to protect jet engine turbine blades from chemicalbook corrosion and rocket nozzles. This will significantly increase the aircraft’s ablation resistance and extend its service-life.

4. Because of its high electrical conductivity. Because of its good electrical conductivity, it can be used to make electrode materials and can be cut with wire EDM into intricate shapes.

5. It is the second phase of a composite material made from particle reinforced metal matrix composite materials. This has been widely used in aerospace and metallurgy.
