Is tantalum carbide coating widely used?

Tantalum carbonide is an metallic cubic crystalline powder which forms a binary compound family with tantalum or carbon. They are extremely tough, fragile, and refractory ceramic material with metallic conductivity. These are brownish-gray powders that can be sintered. This belongs to the sodium-chloride cubic crystal type. Presently, tantalum carbide is used in cemented carbide sintered as a grain growth inhibitor. This significantly slows down grain growth and has a density at 14.3g/cm3.

Molecular weight: 192.956 It is a light metallic cubic-crystalline powder that belongs to the sodium chloride type cubic cristal system. It’s insoluble when dissolved in water. This substance is highly resistant to oxygen and melts quickly when dissolved in potassium pyrosulfate. It has high conductivity. The resistance to 30O at room temperatures is very low, which shows superconductivity.

The most common material used in human life, carbon is high-temperature resistant, thermal conductivity, chemical stability and good heat resistance. These attributes make it a key component of daily life and in the future development and application of science, technology and engineering. A crucible made from graphite has a critical role in preparation of silicon carbide crystals through physical vapor transmission. Because of corrosion at high temperatures on the crucible’s wall, graphite cannot be used to grow crystals. Tantalum carbide can be coated on graphite to solve this problem. Tantalum carbide, a ceramic material can be produced by directly reacting tantalum-containing materials with carbon at high temperature. Due to its high melting points and chemical stability, Tantalum carbide is excellent at resisting corrosion. As a protective coating, it can enhance the quality of graphite, reduce production costs, and improve crystal quality.

Due to tantalum-carbid ceramic’s brittleness and difference in thermal expansion coefficient, the layer bonds poorly with the carbon matrix. The product will have visible cracks and even slippage from the matrix when the coating is prepared or used. High adhesion coatings are therefore essential.

Many factors affect the market value of tantalum-carbide. The market price of tantalum carbide is changing rapidly at the moment. You can contact us anytime if you require it.
