What is NbC powder?

Niobium carbide is a green cubic crystal with a metallic appeal coming from a sodium chloride-type cubic crystal system. Its melting point is high, its hardness is high (microhardness is 235GPa, which is more challenging than diamond), and its chemical stability is good (it is steady at one 000 ~ 1 100 ℃ as well as quickly oxidizes to niobium pentoxide over one 100 ℃). Insoluble substances are hot and cold hydrochloric acid, sulfuric acid, as well as nitric acid, and they are only soluble in the hot mixed service of hydrofluoric acid and also nitric acid. Niobium carbide is simple to thaw in titanium carbide, zirconium carbide, tungsten carbide, as well as various other substances, causing an isomorphic strong service, so it can be made use of to produce cermet, heat-resistant alloy, and sealed carbide. The sealed carbide with niobium carbide has actually improved grain and also boosted all-around performance. The cutting tools made from it likewise have good thermal solidity, thermal shock resistance, as well as thermal oxidation resistance.

? As one of the raw materials of composite ceramic materials, composite ceramic materials constructed from composite ceramic products are typically utilized in wear-resistant components, reducing tools, electrodes, and other areas because of their high solidity, high melting factor, exceptional chemical stability, as well as electric conductivity.

Sealed carbide can not just be utilized as an inhibitor of concrete carbide grain development however likewise form the 3rd distributed stage except WC and also Co together with various other carbides, which can considerably boost the thermal solidity, thermal shock resistance, hot pressing resistance as well as oxidation resistance of concrete carbide. Niobium carbide can be made use of to prepare cemented carbide device materials with exceptional cutting efficiency because of its advantages of enhancing the hardness as well as improving the fracture sturdiness of the alloy.

The hard niobium carbide tough phase of the surfacing-covered electrode enters the structure of the appearing layer, which gives the welding layer a good wear-resistant skeleton and also greatly enhances the wear resistance. The wear resistance of this protected electrode appearing wear-resistant alloy is 1.2 ~ 1.8 times more than that of quenched No. 45 steel (HRC50) and also 2.4 ~ 3.6 times greater than Fe-Cr-C-B wear-resistant alloy. At the very same time, the hard-facing layer can be bonded externally of the work surface without preheating, and the little splits produced on the surface can launch the tension of the hard-facing layer. They will not spread out right into the base product. D. Adding a percentage of niobium carbide to the steel strengthening phase during steelmaking can accomplish the results of precipitation conditioning and also great grain fortifying, thus improving the thorough mechanical residential or commercial properties of steel.

Aerospace parts are utilized as prep work materials for several aerospace devices parts, such as wind turbine rotors, gas tails, blades, engine nozzle linings, as well as architectural members of atomic power plants.

Chemical homes of NbC powder

Niobium carbide is a green cubic crystal with a metallic radiance belonging to a sodium chloride-type cubic crystal system. The loved one density is 8.47, the latticework constant a= 0.447 nm, and the melting point is 2300 ℃. The microhardness is > 235GPA (> 2400kg/mm2), which is harder than diamond. The flexible modulus is 338000N/mm2; the thermal expansion coefficient is 6.65×& times; 10-6/ K, the thermal conductivity is 14w/( m? K), and also the created heat of 1 chemical publication is 40.7 kJ/mol. The certain warm capacity is 36.8 J/( mol? K), and the resistivity is 35 μ ω& mu; & omega;? centimeters 。 Insoluble in cold and hot hydrochloric acid, sulfuric acid, and also nitric acid, soluble in a hot blended service of hydrofluoric acid as well as nitric acid. It is steady at 1000 ~ 1100 ℃ as well as swiftly oxidizes to niobium pentoxide over 1100 ℃. Niobium carbide is very easy to melt in titanium, zirconium carbide, tungsten carbide, as well as various other substances, forming an isomorphic strong service mixture.
