Preparation method and application of tantalum carbide TaC powder

Overview of Tantalum Carbide TaC Powder

Tantalum carbide TaC Powder is a light brown metallic cubic crystal powder belonging to the sodium chloride cubic crystal system. The density is 14.3g/cm3.

Insoluble in water, insoluble in inorganic acid, soluble in mixed acid of hydrofluoric acid and nitric acid and decomposed. It has strong oxidation resistance and is easily melted and decomposed by potassium pyrosulfate. With high electrical conductivity, the resistance is 30Ω at room temperature, showing superconductivity.

Tantalum carbide is used in powder metallurgy, cutting tools, fine ceramics, chemical vapor deposition, hard wear-resistant alloy cutting tools, molds, and additives for wear-resistant and corrosion-resistant structural parts to improve the toughness of alloys. The sintered body of tantalum carbide is golden yellow and can be used as a watch decoration.

Preparation method of tantalum carbide TaC powder

1. Industrially, tantalum pentoxide powder is mixed with a solid carbon ball mill, and reduced and carburized in a non-oxidizing atmosphere (mainly vacuum and argon atmosphere) at 1700 °C to obtain TaC powder with a particle size greater than 2 μm.

2. The nanometer tantalum carbide powder was prepared by heat treatment in a non-oxidizing atmosphere by the liquid precursor method. Add 5 mL of absolute ethanol into a small beaker containing 0.50 g of TaCL5, and stir evenly with a glass rod. Then put it into an ultrasonic cleaning machine with a heating temperature of 55 °C, a working frequency of 40 kHz, and an ultrasonic power of 80 W. After ultrasonic vibration for 5-10min, add 0.10g nanometer activated carbon and continue to shake for 15-20min. Pour into a crucible, spread evenly on the inner wall, and dry with a hot fan. Put the crucible containing the sample into a vacuum hot-pressing furnace, and treat it at a high temperature of 1300 °C in a vacuum of 100 Pa or a hydrogen atmosphere; or in an argon atmosphere of 1400 °C, the holding time is 0.5h, and the heating rate is 20 °C/min. After the experiment, use a brush to brush the product in the crucible.

3. Heating in air to convert into tantalum pentoxide. Can be fused with potassium pyrosulfate. It is prepared by the reaction between metal tantalum and carbon or tantalum pentoxide and black heated to 1900 ℃ in an inert atmosphere.

4. Using tantalum pentoxide and methane as the reaction gas, argon as the carrier, using silicon carbide resistance to radiate heating from the outside, carbonization, or mixing tantalum pentoxide and carbon black, pressurized powder molding, heating in hydrogen or vacuum .

Application of tantalum carbide TaC powder

Widely used in industry and military. In cemented carbide, it is widely used as an additive. Its main function is to improve the high temperature strength of cemented carbide and inhibit the growth of tungsten carbide particles.

In cutting tools, used as a hard coating to increase the chemical resistance and wear resistance of the base metal;

In the military, it can be used as a coating for jet engine turbine blades and rocket nozzles, which can significantly improve their ablation resistance and prolong their service life.

Because of its good conductivity, it can also be used as an electrode material, which can be cut into complex shapes by discharge wire;

And as a second-phase particle reinforced metal matrix composite material, it can be used in aerospace, metallurgy, building materials, electric power, hydropower, mining and other fields.
