Common refractory raw materials include:
Alumina: Alumina is a common refractory raw material with good high temperature resistance and corrosion resistance. It is often used to make refractory bricks, refractory coatings, etc.
Silicate materials: including silicate minerals and silicate glass, such as silica, quartz, feldspar, etc., which are often used to make refractory ceramics, refractory glass, etc.
Carbon materials: such as graphite, silicon carbide, etc., have good high temperature resistance and are often used to make refractory bricks, refractory coatings, etc.
High-aluminum materials: including high-aluminum ore and high-alumina cement, which have high temperature stability and corrosion resistance and are often used to make refractory bricks, refractory cement, etc.
Mullite: Mullite is an aluminum-silicon-containing mineral with good fire-resistant properties and is often used in the manufacture of refractory ceramics, refractory coatings, etc.
Magnesium oxide: Magnesium oxide has good high temperature resistance and corrosion resistance, and is often used to make refractory bricks, refractory coatings, etc.
Borate materials: such as borax, sodium borate, etc., have good high temperature resistance and corrosion resistance, and are often used in the manufacture of refractory ceramics, refractory coatings, etc.
Light clay: Light clay has good fire resistance and processing properties, and is often used to make lightweight refractory bricks, refractory insulation materials, etc.
