Overview and application of chromium silicide

Chromium silicide, a chemical substance, is a gray square prism crystal.

Ecological data

Usually it is not harmful to water. If there is no government permission, do not discharge the material into the surrounding environment.

Chromium silicide synthesis method

1. After the silicon powder and chromium powder are mixed, they are roasted in hydrogen at 900-1100°C and then cooled. Or the mixture of chromium powder and silicon powder and the mixture of silicon dioxide powder and silicon powder are uniformly mixed, and calcined in a hydrogen stream. The volatile SiO formed by SiO2 and Si powder escapes with Na and K in the raw material to obtain CrSi2.

2. Cr3Si (cubic crystal) melting point of about 1710℃, Cr5Si3 (tetragonal crystal, melting point about 1600℃), CrSi (cubic crystal, melting point about 1600℃) can be obtained by eutectic melting or sintering of chromium and silicon powder in vacuum or under the protection of hydrogen. ), CrSi2 and Cr3Si2.

3.48.1 parts of chromium powder with a particle size of 1100μm are mixed with 51.9 parts of silicon powder with a particle size of 50μm, and 3 parts of SiO2 powder with a particle size of 10μm are mixed with 1.5 parts of silicon powder. The two mixtures are mixed again. When calcined in a hydrogen stream at 1100°C for 1 hour, and then at 1430°C for 10 minutes, the volatile SiO formed by SiO2 and Si powder escapes with Na and K in the raw materials to obtain a CrSi2 sintered body with fine powder and only Na containing.

0.5×10-6, K0.1×10-6.
