What is the chemical stability of niobium carbide

What is NbC powder?

Niobium carbide is an environment-friendly cubic crystal with a metal luster coming from a sodium chloride-type cubic crystal system. Its melting point is high, its firmness is high (microhardness is 235GPa, which is more challenging than corundum), and also its chemical security is good (it is steady at one 000 ~ 1 100 ℃ as well as quickly oxidizes to niobium pentoxide over one 100 ℃). Insoluble compounds are hot and cold hydrochloric acid, sulfuric acid, as well as nitric acid, and they are only soluble in the hot mixed option of hydrofluoric acid and nitric acid. Niobium carbide is simple to thaw in titanium carbide, zirconium carbide, tungsten carbide, and also other compounds, leading to an isomorphic strong remedy, so it can be utilized to produce cermet, heat-resistant alloy, and also cemented carbide. The sealed carbide with niobium carbide has improved grain and enhanced all-around efficiency. The cutting tools made from it also have great thermal hardness, thermal shock resistance, and thermal oxidation resistance.

? As one of the raw materials of composite ceramic materials, composite ceramic materials made from composite ceramic products are frequently made use of in wear-resistant parts, cutting tools, electrodes, as well as various other areas as a result of their high hardness, high melting factor, outstanding chemical security, and also electric conductivity.

Sealed carbide can not only be used as an inhibitor of cemented carbide grain development yet additionally form the 3rd distributed stage other than WC as well as Co along with various other carbides, which can significantly boost the thermal hardness, thermal shock resistance, warm pushing resistance as well as oxidation resistance of concrete carbide. Niobium carbide can be used to prepare cemented carbide tool products with outstanding cutting performance because of its advantages of enhancing the solidity as well as boosting the fracture durability of the alloy.

The tough niobium carbide hard stage of the surfacing-covered electrode gets in the framework of the appearing layer, which gives the welding layer a great wear-resistant skeletal system as well as substantially boosts the wear resistance. The wear resistance of this covered electrode surfacing wear-resistant alloy is 1.2 ~ 1.8 times greater than that of quenched No. 45 steel (HRC50) and 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 on the surface of the workpiece without preheating, as well as the tiny splits generated externally can launch the tension of the hard-facing layer. They will not spread out into the base product. D. Including a percentage of niobium carbide to the steel reinforcing phase throughout steelmaking can achieve the results of rainfall strengthening as well as great grain strengthening, therefore improving the extensive mechanical properties of steel.

Aerospace parts are used as preparation materials for several aerospace equipment components, such as wind turbine rotors, gas tails, blades, engine nozzle cellular linings, and also architectural members of nuclear reactors.

Chemical buildings of NbC powder

Niobium carbide is an eco-friendly cubic crystal with a metal gloss belonging to a salt chloride-type cubic crystal system. The family member thickness is 8.47, the lattice constant a= 0.447 nm, as well as the melting point is 2300 ℃. The microhardness is > 235GPA (> 2400kg/mm2), which is harder than diamond. The elastic modulus is 338000N/mm2; the thermal growth coefficient is 6.65×& times; 10-6/ K, the thermal conductivity is 14w/( m? K), as well as the produced warmth of 1 chemical book is 40.7 kJ/mol. The specific warmth capability is 36.8 J/( mol? K), and also 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 mixed service of hydrofluoric acid and nitric acid. It is secure at 1000 ~ 1100 ℃ and swiftly oxidizes to niobium pentoxide above 1100 ℃. Niobium carbide is very easy to melt in titanium, zirconium carbide, tungsten carbide, and also other substances, developing an isomorphic strong option blend.
