DESCRIPTION
The reason why silicon metal can be used in the manufacture of alumina ceramics is because silicon metal has high chemical stability and high melting point, resistant to high temperature and corrosion, and can form a stable chemical reaction with alumina to form alumina ceramics.
For example, alumina ceramics are commonly used in industrial applications in harsh environments such as high temperature, high pressure and chemical corrosion, such as petrochemical, aerospace, energy and other fields. In these applications, alumina ceramics require high temperature stability, chemical stability and mechanical strength. The addition of silicon metal can improve the performance of alumina ceramics.
