What does NbC powder mean?
Niobium carbonide is an green cubic crystal with metallic luster. It belongs to a type of cubic crystal that contains sodium chloride. It has high melting points, high hardness, and is faster than corundum. They are insoluble in both hot and cold hydrochloric, sulfuric, and nitric compounds. However, they can only be dissolved in hot mix of hydrofluoric, nitric, acid. The melting of Niobium Carbide in titanium carbide and zirconium caride and other compounds results in an isomorphic liquid solution. It can then be used in the production of cemented carbide and heat-resistant alloys, such as cermet. Cemented carbide that contains niobium caride can have refined grains and better performance. This cutting tool has good thermal hardness and resistance to thermal shock.
How is NbC powder applied?
Because of their hardness and high melting point as well as excellent chemical stability and electrical conductivity, composite ceramic materials from composite clay materials are used in many fields, including cutting tools, electrodes and wear-resistant parts.
Cemented carbide can be used to inhibit cemented-carbide grain growth. It can also form the third phase other than WC and Co with other carbides. This will significantly increase the thermal hardness and thermal shock resistance as well as the resistance to hot pressing and oxidation of cemented carbonide. Cemented carbide tool material can be prepared using Niobium carbide. This is due to its benefits of improving hardness as well as increasing fracture toughness.
The hard niobium carbonide hard phase in the surfacing-covered electro enters the structure and enhances its wear resistance. This wear resistance alloy of covered electrode surfacing is wear-resistant, 1.21.8x greater than the HRC50 quenched No.45 Steel and 2.53.6x more than Fe-Cr–C-B. The surface can still be covered with the hard-facing layers. Additionally, they can also be easily welded to it without heating. They won’t spread to the base material. The addition of small amounts of niobium carbonide during steelmaking to the steel strength phase can produce the benefits of precipitation strengthening.
Many aerospace components can be used to prepare parts for other equipment, like turbine rotors or gas rudders.
Chemical Properties of NbC dust
The green cubic crystal Niobium carbide has a metallic luster and is of sodium chloride type. The melting point of 2300 is achieved by the relative density being 8.47. It is much harder than corundum because the microhardness of >235GPA (>2400kg/mm2) is higher. The elastic modulus for corundum is 338000N/mm2. K; and the generated heat for 1 chemical books is 40.7kJ/mol. 36.8J/(mol) is the specific heat potential K and the resistivity of 35 m? It is insoluble in both hot and cold sulfuric acids, hot and low hydrochloric acids, and nitric Acid. However, it can be dissolved in a mixture of hot hydrofluoric acid or nitric. It’s stable from 1000 to 1100, and it quickly oxidizes in niobium peroxide over 1100. The melting of niobium carbide in titanium, zirconium, or tungsten carbide creates an isomorphic solution.
