Explanation
inorganic nonmetallic materials that can be used in high temperature environment and has a refractoriness of no less than 1580 ℃. It can be divided into three categories: acidic, neutral, and alkaline; Burned or unburned products; Fixed or amorphous products. Commonly used materials include siliceous, clay, high alumina, corundum, magnesium aluminum spinel, magnesium, magnesium calcium, carbon composite materials, carbide, nitride, and oxide and non oxide composite materials.
