Overview of Niobium Carbide NBC Powder
Niobium carbide (NBC and Nb2C) is a very hard refractory ceramic material used commercially for cutting tool tips. It is usually processed by sintering and is a commonly used additive in cemented carbide as a grain growth inhibitor. The appearance is brown-gray metal powder with purple luster and strong corrosion resistance.
How is Niobium Carbide NbC powder produced?
Niobium pentoxide reduction method:
Niobium carbide can be obtained by heating niobium oxide in a vacuum at 1800°C and adding coke.
In industry, niobium carbide is usually prepared from niobium pentoxide and carbon black as raw materials: niobium pentoxide and carbon black are firstly mixed with carbide raw materials in proportion, and put into a graphite crucible. Heating hydrogen or vacuum to 1600～1800℃, carbonization for the first time, then adding carbon black, mixing it, heating to 1800～1900℃ under hydrogen or vacuum, secondary carbonization, this is niobium carbide.
Application of Niobium Carbide NBC Powder
Niobium carbide NBC powder can partially replace tantalum carbide and is widely used in refractory high temperature materials and cemented carbide additives
As a cemented carbide additive, niobium carbide is a solid solution component of ternary and quaternary carbides, such as WC-NBC-C ternary system.
Niobium carbide NBC powder can also be used to make purple artificial gemstones.
