What is Tantalum carbide ?? Tantalum carbide ? Tantalum crystalline powder , a light brown metallic cube crystalline powder that belongs to the sodium chloride type cubic system. Tantalum carbide can also be used as a cemented carbonide sintered crystal growth inhibitor. This has a significant impact on inhibiting crystal growth. It has a density 14.3g/cm3, and is insoluble or hardly soluble with mineral acids. It can also be soluble in a mix acid of hydrofluoric acid/nitric acid and can be broken down. Tantalum caride is highly resistant to oxidation, melts easily with potassium pyrosulfate and can be decomposed.
What is the rystal structure of Tantalum Caride?
TaCx compounds possess a cubic (rock salt) crystal structure when x is between 0.7 and 1.0. The lattice parameter for TaC0.5 compounds increases with x. It has two major crystal forms. The most stable has an anticadmium iodide type trigonal structure. It transforms upon heating up to 2000°C into a hexagonal, non-long-range lattice for carbon atoms.
Tantalum carbide microhardness
The tantalum-carbid surface gradient composite material’s microhardness is measured from the surface to its matrix. The microhardness test must be performed every 50mm from the surface. It can be seen from the distribution of the test hardness that the surface microhardness value for the tantalum carbide composite material surface gradient composite material is as high as 2123HV0.02. The microhardness values for the nano TaC layer are 1980-2025HV0.02, 17502010HV0.02, 16401710HV0.02 and the TaC dispersion layers are 16401710HV0.02. Although the TaC layer’s microhardness decreases with increasing distance from the surface, it can still reach 5.5 to 7.0 times that of the gray cast-iron matrix.
What is the strength of tantalum carbide.
Tests of Vickers hardness and fracture toughness were done to confirm that TaC has the highest mechanical properties at 5.5 GPa. TaC has a relative density of 7.4 MPa m1/2, Vickers hardness at 21.0 GPa and fracture toughness of 97.7%.
Is tantalum carbide toxic?
Tantalum Compounds – The systemic toxicity of tantalum oxide as well as metallic tantalum is very low. This may be due to the poor solubility of tantalum. Carbides – Pure carbon has a low level of toxicity and can be used and ingested as graphite or charcoal.
