How is Niobium Silicide NbSi2 Powder produced?
Taking niobium and silicon as raw materials, the metal niobium and silicon are crushed and fully mixed into the graphite furnace. The furnace is heated and heated gradually. When the temperature reaches 1000℃, the metal reacts, and then hydrogen is added to make the temperature rise to 1400 ~ 1900℃, and then the reaction continues. Niobium pentoxide and silicon metal can also be put into the reduction furnace so that it is reduced at 1400℃ for more than 30 minutes, that is, niobium silicide.

Application of Niobium Silicide NbSi2 Powder:
Niobium Silicide NbSi2 powders can be combined with zirconium disilicate, molybdenum disilicate and tungsten trisilicate to form a solid solution and used as raw materials for fine ceramics. Niobium Silicide NbSi2 powder can also be used in niobium silicate-based turbine components, integrated circuits, high-temperature structural materials, etc.

Packing & Shipping of Niobium Silicide NbSi2 Powder:
We have many different kinds of packing which depend on the niobium silicide NbSi2 powder quantity.
Niobium silicide NbSi2 powder packing: vacuum packing, 1kg/bag, 25kg/barrel, or as your request.
Niobium silicide NbSi2 powder shipping: could be shipped out by sea, by air, by express as soon as possible once payment receipt.
