Niobium (Nb) is a refractory metal with a high melting point (2468°C), moderate density, corrosion resistance, radiation resistance, high temperature strength, and good high temperature mechanical properties. The excellent properties of niobium and niobium alloys make it one of the important candidate materials for high-temperature structural parts in the aviation, aerospace and nuclear industries, and can be used to manufacture key components such as rocket engines and nuclear reactors. However, its oxidation performance is poor. Pure niobium undergoes "pest" oxidation at 600°C. As the temperature increases, the degree of oxidation intensifies, eventually leading to the failure of its high-temperature performance. This shortcoming severely restricts niobium and niobium. Application of alloys. In order to improve its high temperature oxidation resistance, surface coating protection is a practical and effective way to balance the high temperature mechanical properties and oxidation resistance of niobium and niobium alloys. When niobium silicide (NbSi2) is oxidized, SiO2 oxide film can be formed on the surface. The oxide film is dense, self-healing, and has good high temperature oxidation resistance, making NbSi2 the main choice for high temperature protective coatings for niobium and niobium alloys.

Application of niobium silicide powder:

1. Synthesis of niobium/niobium silicide composite materials.
2. Prepare a ceramic aluminum plate.
3. Prepare an alumina ceramic material with good toughness.
4. Prepare a silicon-germanium alloy-based thermoelectric element.
