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 boiled, but insoluble in organic acid. This powder is also soluble and dissolves in the mixture of hydrofluoric, nitric, and other acids. This substance is highly resistant to oxygen and melts quickly when dissolved in potassium pyrosulfate. It has high conductivity. The resistance of 30O at normal temperature is a sign that it’s superconductive.

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. Due to high temperatures and corrosion of raw materials, graphite crucible is not suitable for crystal growth. Tantalum carbide can be coated on graphite to solve this problem. Tantalum carbide, a ceramic material can be produced by reacting tantalum-containing materials with carbon at high temperature. Due to its high melting points and chemical stability, Tantalum carbide is capable of resisting corrosion from various chemicals at high temperatures. As a coating for graphitecrucibles, it is able to protect, enhance the quality of crystals, reduce production costs, and increase reuse rates.

Due to tantalum carbide’s brittleness, and the differences in the thermal expansion coefficient, between the carbon matrix and the coating, the bonding strength between the layers is weak. The quality of the finished product can be affected by visible cracks in the coating or falling off the matrix. 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.
