Why tantalum carbide is a super high-temperature resistant ceramic

What is Tantalum Carbide? Tantalum carbide A black, brown, metallic powder that is cubic in structure, has a relative density of 13.9 and a melting temperature of 3880. The boiling point is 5500. It is a mix of 75% tantalum caride and 25% hafnium carbonide. The melting point for this mixture is more than 4200. It is extremely stable in chemical terms. It is insoluble when it comes into contact with water. Tantalum pentachloride is used to heat the material with silicon carbide resistance. It's used in the manufacture of cutting tools. Tantalum carbonide (TaC), a member the ultra-high temperatures resistant ceramic family has a high melt point (3880 ), high toughness (20GPa), a high elastic modulus (445GPa) and good conductivity. (25 ), 42.1 mO * cm-1 and 22W *m-1 * K-1), Chemical resistance, good thermal shock resistance.

Use of tantalum carbide
Tantalum carbide can be used widely in tools steel, wear-resistant components, conductive films and optical coatings. You can prepare aluminum single crystals using Tantalum nitride crucibles.

Making tantalum carbide
Tantalum pentoxide can be used as a raw material. In a reduction oven, combine tantalum pentoxide fully with carbon black. You can reduce the mixture in hydrogen, or at 1500 under vacuum to make tantalum carbide powder. For a more thorough reduction of the inert gases, heat them up to 1900 in an inert gaz and then carbonize under vacuum to make tantalum carbide. You can also reduce tantalum peroxide with aluminium in a graphitecrucible. Heat the solution to 2000°C. Add pure graphite block. After the aluminum carbide is formed, cooling is used. Finally, inorganic acid is added. To make finer particles of tantalum carbide, it can be carbonized directly with metal tantalum or carbon black.

Prices for tantalum carbide
Price of Tantalum Carbide will be affected by the size and purity of the particles. The purchase volume may also have an effect on cost. Large quantities of small amounts will result in a lower price. On our official website, you can see the price for tantalum-carbide.
