Introduction to Tantalum Carbide TAC Powder Tantalum carbide Oder TaC It is a light-brown metallic cubic crystal powder belonging to the sodium chloride cubic cristal system. It is 14.3g/cm3.
Insoluble in water, insoluble with inorganic acid, soluble hydrofluoric acid, and nitric acids mixed acid and degradation. It is strong in oxidation resistance, and easily melts and decomposes by potassiumpyrosulfate. Superconductivity is demonstrated by its high conductivity and resistance to 30O at room temperatures.
Tantalum carbide This is used for powder metalurgical, cutting tools and chemical vapor deposition. It also makes hard-wear-resistant alloy cutting tools. Tantalum carbide can be used to decorate watches with its sintered body. It has a golden color.

Preparation Methods for Tantalum Carbide TaC powder
1. For TaC powder, mix tantalum pentoxide and solid carbon ball mills. At 1700, the mixture should be reduced and carburized in an oxygen-free atmosphere (mainly vacuum or argon).
2. By heat treating in a non-oxidizing environment using the liquid precursor, nano tantalum caride powder was obtained. A small glass rod was used to stir 5mL of anhydrousethanol into a small vessel containing 0.50gTaCL5. It was heated to 55°C and worked at 40kHz. Ultrasonic power was 80W. After ultrasonic oscillation lasting 5-10 minutes, 0.10g nanoactivated carbon was added. The oscillation continued for 15-20 minutes. Then, pour it into the crucible. Coat it well on the inner wall. Dry it with a hot fan. The sample was placed in the crucible and heated in a vacuum hot pressing furnace. Use a brush to brush the products in a crucible after the experiment.
3. Tantalum pentoxide can be converted to heat in the atmosphere Potassium pyrosulfate can be fused. Tantalum and carbon, or tantalum pentoxide, and black in an inert environment heated to 1900 reaction.
4. Use tantalum pentoxide or methane as the reaction gases, argon to carry it, silicon carbide resistance against the external radiation heating or carbonization, tantalum pentoxide combined with carbon black, pressurized mold, heating in hydrogen, or vacuum.

Tantalum Carbide TaC Powder
It is used in industry as well as the military. It is used extensively in cemented carbide as an additive. It serves two main functions: it increases the high temperature strength of cemented carbide and inhibits the growth of tungsten-carbidide particles.
Use as a hard coating on cutting tools to increase the wear resistance and chemical resistance of the base material.
It can be used by the military as a coating on jet engine turbine blades.
Its high conductivity allows it to be used as an electrode material by using electric discharge wires to create complex shapes.
The second phase of the particle reinforced metal matrix composites can be used in aerospace and metallurgy as well as for electric power, hydropower, mining, among other applications.
