What is NbC powder?
Niobium carbide is an eco-friendly cubic crystal with a metallic appeal coming from a sodium chloride-type cubic crystal system. Its melting factor is high, its hardness is high (microhardness is 235GPa, which is harder than corundum), and its chemical security is great (it is secure at one 000 ~ 1 100 ℃ and swiftly oxidizes to niobium pentoxide above one 100 ℃). Insoluble substances are hot and cold hydrochloric acid, sulfuric acid, as well as nitric acid, and also they are just soluble in the warm combined remedy of hydrofluoric acid and nitric acid. Niobium carbide is simple to melt in titanium carbide, zirconium carbide, tungsten carbide, as well as various other compounds, leading to an isomorphic strong option, so it can be utilized to make cermet, heat-resistant alloy, as well as sealed carbide. The sealed carbide with niobium carbide has improved grain and enhanced all-around efficiency. The cutting devices constructed from it also have excellent thermal hardness, thermal shock resistance, as well as thermal oxidation resistance.

? As one of the raw products of composite ceramic materials, composite ceramic materials made of composite ceramic materials are commonly made use of in wear-resistant components, reducing tools, electrodes, as well as other areas due to their high hardness, high melting point, excellent chemical security, as well as electric conductivity.
Cemented carbide can not only be made use of as a prevention of concrete carbide grain growth yet likewise form the third distributed stage except WC as well as Carbon monoxide together with other carbides, which can substantially enhance the thermal firmness, thermal shock resistance, warm pressing resistance as well as oxidation resistance of cemented carbide. Niobium carbide can be utilized to prepare concrete carbide device materials with excellent reducing performance because of its benefits of increasing the firmness as well as boosting the fracture sturdiness of the alloy.
The difficult niobium carbide tough stage of the surfacing-covered electrode goes into the framework of the appearing layer, which provides the welding layer an excellent wear-resistant skeleton and also considerably boosts the wear resistance. The wear resistance of this protected electrode surfacing wear-resistant alloy is 1.2 ~ 1.8 times greater than that of quenched No. 45 steel (HRC50) as well as 2.4 ~ 3.6 times more than Fe-Cr-C-B wear-resistant alloy. At the same time, the hard-facing layer can be welded externally of the workpiece without pre-heating, and also the little fractures produced externally can launch the tension of the hard-facing layer. They will certainly not spread out into the base product. D. Including a small amount of niobium carbide to the steel enhancing stage throughout steelmaking can accomplish the results of precipitation conditioning and great grain strengthening, hence improving the thorough mechanical properties of steel.
Aerospace parts are utilized as prep work materials for numerous aerospace equipment components, such as turbine rotors, gas tails, blades, engine nozzle cellular linings, as well as architectural participants of nuclear reactors.
Chemical residential properties of NbC powder
Niobium carbide is a green cubic crystal with a metallic appeal belonging to a sodium chloride-type cubic crystal system. The family member density is 8.47, the latticework constant a= 0.447 nm, and also the melting factor is 2300 ℃. The microhardness is > 235GPA (> 2400kg/mm2), which is tougher than corundum. The flexible modulus is 338000N/mm2; the thermal growth coefficient is 6.65×& times; 10-6/ K, the thermal conductivity is 14w/( m? K), and also the produced warm of 1 chemical publication is 40.7 kJ/mol. The details warm capacity is 36.8 J/( mol? K), as well as the resistivity is 35 μ ω& mu; & omega;? centimeters 。 Insoluble in cold and hot hydrochloric acid, sulfuric acid, and nitric acid, soluble in a warm blended remedy of hydrofluoric acid and nitric acid. It is steady at 1000 ~ 1100 ℃ as well as quickly oxidizes to niobium pentoxide over 1100 ℃. Niobium carbide is very easy to melt in titanium, zirconium carbide, tungsten carbide, and also other substances, forming an isomorphic strong solution mix.
