How is niobium silicide NbSi2 powder produced?

Overview of Niobium Silicide NbSi2 Powder

Niobium silicide NbSi2 powder (CAS 12034-80-9) has high melting point, high corrosion resistance, high oxidation resistance, good conductivity, high temperature ductility, and is the intermediate phase of the binary alloy system.

Niobium silicide (NbSi2) is a gray hexagonal crystal. The relative density is 5.7. The lattice constant port is 0.4863nm, C = 0.6604nm. The melting point is 1950℃, the microhardness is 10.3GPa (1050kg/mm2), the Vickers hardness is 5.88~6.88GPa (600~700kg/mm2), the conductivity is 50.4×10-4 S/m, and the thermal expansion coefficient is 7.3×10-6. ℃_1. It is insoluble in water, concentrated hydrochloric acid, concentrated sulfuric acid, and easily soluble in a mixed solution of hydrofluoric acid and sulfuric acid.

How is niobium silicide NbSi2 powder produced?

Using niobium and silicon as raw materials, the metal niobium and silicon are crushed and thoroughly mixed into a graphite furnace. Heat the furnace and gradually heat up. When the temperature reaches 1000°C, the metal reacts, and then hydrogen is added to increase the temperature to 1400~1900°C, and then the reaction continues. It is also possible to put niobium pentoxide and metallic silicon in a reduction furnace for reduction at 1400°C for more than 30 minutes, that is, niobium silicide.

Niobium silicide NbSi2 powder application

Niobium silicide NbSi2 powder can be mixed with zirconium disilicate, molybdenum disilicate and tungsten trisilicate to form a solid solution, and used as a raw material for fine ceramics. Niobium silicide NbSi2 powder can also be used for niobium silicate-based turbine parts, integrated circuits, high-temperature structural materials, etc.
