Characteristics and applications of niobium carbide

Niobium carbide is a green cubic crystal with metallic luster and belongs to the sodium chloride type cubic crystal system. Niobium carbide is a metal carbide with the chemical formula NbC.

Characteristics of niobium carbide

Niobium carbide has a melting point of 3500°C and a microhardness >23.5Gpa (>2400kg/mm2), which is harder than corundum. The elastic modulus of niobium carbide is 338000 N/mm2, the thermal expansion coefficient is 6.65×10^(-6)/K, the thermal conductivity is 14w/(m·K), and the resistivity is 35μΩ·cm.

Niobium carbide is insoluble in cold and hot hydrochloric acid, sulfuric acid and nitric acid, but soluble in a mixed solution of hot hydrofluoric acid and nitric acid. It is stable at 1000～1100℃, and rapidly oxidizes to niobium pentoxide above 1100℃. Niobium carbide is easy to melt in compounds such as titanium carbide, zirconium carbide and tungsten carbide, and together form a uniform solid solution mixture.

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 carbides as a grain growth inhibitor. The appearance is brown-gray metal powder with purple luster and strong corrosion resistance.

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

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

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

Niobium carbide NBC powder is insoluble in hot and cold hydrochloric acid, sulfuric acid and nitric acid, but soluble in a mixed solution of hot hydrofluoric acid and nitric acid.

 Niobium carbide NBC powder is easily soluble in titanium carbide, zirconium carbide, tungsten carbide and other compounds, forming a uniform solid solution mixture together, and is a commonly used cemented carbide additive.

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 for cemented carbide, niobium carbide is a solid solution component of ternary and quaternary carbides, such as the WC-NBC-C ternary system.

Niobium carbide NBC powder can also be used to make purple artificial gems.
