Types
1.Classification by chemical mineral composition
Silicon, aluminum silicate, magnesium chromium, zirconium, silicon carbide and carbon-containing, as well as carbonaceous materials
Special refractory materials, such as pure oxides, carbides, nitrides, silicides, borides and metal ceramics, etc.
2.Classification by porosity
Those with an apparent porosity of less than 3% are classified as extra-dense products
Those with an apparent porosity of 3% to 10% are classified as high-dense products
Those with an apparent porosity of 10% to 16% are classified as dense products
Those with an apparent porosity of 16% to 20% are classified as sintered products
Those with an apparent porosity of 20% to 30% are classified as ordinary products
Those with an apparent porosity of 45% to 85% are classified as lightweight products
Those with an apparent porosity of 45% to 85% are classified as ultra-lightweight products
Tunnel kiln
Applications
