Why tantalum carbide has strong oxidation resistance?

What is tantalum-carbide? Tantalum carbide It is a metallic, light-brown cubic crystalline powder of the sodium chloride type cubic cristal system. Tantalum carbid is a cemented-carbidide growth inhibitor that sinters grain. It has a density 14.3g/cm3. It is insoluble, insoluble, inorganic, soluble, mixed acid of hydrofluoric and nitric acids, and can also be decomposable. It's a good antioxidant. It exhibits a high conductivity and resistance to heat of up to 30 O. It exhibits superconductivity. It's used in powder metalurgical, cutting tools and chemical vapour deposition. It can also be used to make watch ornaments by its sintered body made of tantalum carbonide.

Tantalum Carbide TaC Composites
Macrostructure: For one hour, the sample reacts at 1160 to create a TaC/Fe gradient compound. A macroscopical observation shows the obvious gradient in the reaction layer, uniform transition, good combination with matrix, and no apparent peeling phenomena. The reaction zone's thickness is around 1180 m.m. during the diffusion-reaction.
Check the structure and composition of your composite material samples by performing XRD analyses. A reaction zone exists: Fe, TaC., G (graphite), with Fe and Ta intermediate phases and Ta2C. This temperature is where the diffusion reaction takes place. C diffuses and participates in the reaction. On the area's square particles and cubic particles, point energy spectrum analysis was done. It was found that the reaction area contained a low amount of Fe and C. There were also fewer Ta, C. Ta particles in the square-particle phase. Also, the ratio of C to Fe was very close to 1. Because TaC and TaC are products that can be dissolved into austenite, TaC may form from precipitation. But some Fe remains in TaC so it is not difficult to detect a little Fe. It is believed that cuboid as well as cube particles, are both TaC.

The microhardness of tantalum caride
A microhardness test was performed to determine the microhardness in TaC's surface gradient composites. It can be observed that TaC surface-grade composites are up to 2123HV0.02 from the measured distribution of hardness. These include the microhardnesses of the nano TaC layers, which is 19802025HV0.02, as well as the microhardnesses of micron TaC layers (17502010HV0.02) and 16401710HV0.02. As the layer is further away from the surface, its microhardness decreases. However, it can still be 5.57.0 times as hardened than the grey cast-iron matrix.

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.
