What is the chemical stability of niobium carbide

What is NbC powder?

Niobium carbide is an eco-friendly cubic crystal with a metallic luster belonging to a salt chloride-type cubic crystal system. Its melting factor is high, its firmness is high (microhardness is 235GPa, which is tougher than corundum), as well as its chemical stability is great (it is steady at one 000 ~ 1 100 ℃ and also swiftly oxidizes to niobium pentoxide above one 100 ℃). Insoluble compounds are hot and cold hydrochloric acid, sulfuric acid, and also nitric acid, as well as they are only soluble in the hot mixed remedy of hydrofluoric acid as well as nitric acid. Niobium carbide is simple to melt in titanium carbide, zirconium carbide, tungsten carbide, as well as various other compounds, causing an isomorphic solid option, so it can be used to make cermet, heat-resistant alloy, and sealed carbide. The sealed carbide with niobium carbide has fine-tuned grain and also boosted well-rounded efficiency. The cutting tools made from it additionally have excellent thermal solidity, thermal shock resistance, as well as thermal oxidation resistance.

? As one of the raw products of composite ceramic products, composite ceramic materials made of composite ceramic materials are commonly utilized in wear-resistant parts, reducing devices, electrodes, and various other fields because of their high solidity, high melting factor, excellent chemical security, and electric conductivity.

Sealed carbide can not only be utilized as a prevention of concrete carbide grain growth yet likewise form the third dispersed stage other than WC and also Co together with various other carbides, which can dramatically enhance the thermal hardness, thermal shock resistance, hot pressing resistance and oxidation resistance of cemented carbide. Niobium carbide can be used to prepare cemented carbide device products with outstanding reducing efficiency as a result of its advantages of boosting the solidity and also improving the fracture sturdiness of the alloy.

The hard niobium carbide difficult stage of the surfacing-covered electrode gets in the framework of the surfacing layer, which offers the welding layer a good wear-resistant skeleton as well as substantially boosts the wear resistance. The wear resistance of this protected electrode appearing wear-resistant alloy is 1.2 ~ 1.8 times higher than that of quenched No. 45 steel (HRC50) and 2.4 ~ 3.6 times more than Fe-Cr-C-B wear-resistant alloy. At the very same time, the hard-facing layer can be bonded externally of the workpiece without preheating, and the small fractures generated on the surface can release the anxiety of the hard-facing layer. They will certainly not spread right into the base product. D. Adding a small amount of niobium carbide to the steel strengthening phase throughout steelmaking can accomplish the effects of rainfall fortifying and also great grain fortifying, therefore enhancing the detailed mechanical buildings of steel.

Aerospace parts are utilized as preparation products for several aerospace equipment components, such as generator blades, gas rudders, blades, engine nozzle linings, and also structural participants of atomic power plants.

The loved one density is 8.47, the latticework constant a= 0.447 nm, as well as the melting factor is 2300 ℃. The microhardness is > 235GPA (> 2400kg/mm2), which is harder than corundum. The elastic modulus is 338000N/mm2; the thermal expansion coefficient is 6.65×& times; 10-6/ K, the thermal conductivity is 14w/( m? K), and the generated warm of 1 chemical book is 40.7 kJ/mol. The particular warmth ability is 36.8 J/( mol? K), as well as the resistivity is 35 μ ω& mu; & omega;? cm 。 Insoluble in hot and cold hydrochloric acid, sulfuric acid, and nitric acid, soluble in a hot mixed remedy of hydrofluoric acid and nitric acid. It is steady at 1000 ~ 1100 ℃ and rapidly oxidizes to niobium pentoxide over 1100 ℃. Niobium carbide is easy to melt in titanium, zirconium carbide, tungsten carbide, as well as various other substances, developing an isomorphic solid remedy mixture.
