The preparation and application of Niobium Carbide

Overview of Niobium Carbide NbC Powder

Niobium carbide (NbC and Nb2C) is an extremely hard refractory ceramic material, commercially used in tool bits for cutting tools. It is usually processed by sintering and is a frequent additive as grain growth inhibitor in cemented carbides. It has the appearance of a brown-gray metallic powder with purple lustre. It is highly corrosion resistant.

 Niobium carbide can be produced by the heating of niobium oxide in a vacuum at 1800 °C and adding coke.

 Niobium carbide NbC powder is a dark gray-brown powder with a cubic crystal structure and a metallic luster. It is stable at 1000 to 1100 °C and rapidly oxidizes to niobium pentoxide above 1100 °C.

 Niobium carbide NbC powder has good chemical stability and high temperature performance. It is a high melting point and high hardness material.

 Niobium carbide NbC powder is insoluble in cold and hot hydrochloric acid, sulfuric acid, and nitric acid, and it is soluble in hot hydrofluoric acid and nitric acid mixed solution.

 Niobium carbide NbC powder is easily melted in compounds such as titanium carbide, zirconium carbide, and tungsten carbide, and together forms a homogeneous solid solution mixture, which is a commonly used cemented carbide additive.

Application of Niobium Carbide NbC Powder

Niobium carbide NbC powder, as a partial substitute for tantalum carbide, is widely used in refractory high-temperature materials and cemented carbide additives

As a carbide hard alloy additive, niobium carbide is a ternary and quaternary carbide solid solution component, such as the WC-NbC-C ternary system and the like.

Niobium carbide NbC powder can also be used to make purple artificial gemstones.
