There are many classification methods for refractory materials. According to their chemical properties, they can be divided into three categories: acidic refractory materials, alkaline refractory materials and neutral refractory materials.
According to the main mineral chemical components of refractories, they can be divided into: siliceous refractories, aluminosilicate refractories, magnesia refractories, magnesia spinel refractories, magnesia chromium refractories, magnesia dolomite refractories Refractories, dolomite refractories, carbon composite refractories, high alumina refractories, chromium refractories, zirconium refractories, etc.
Classified according to the form of supply, it can be divided into two types: shaped and unshaped refractories.
According to different classifications of refractoriness, they are divided into ordinary/advanced/super-grade/super refractory materials; those with a temperature resistance of 1580~1770℃ are called ordinary refractories, advanced refractories can withstand high temperatures of 1770~2000℃, and those with high temperature resistance of 2000~3000℃ are called Special-grade refractories, those above 3000℃ are called super refractories.
According to the classification of bulk density, it can also be divided into light/heavy refractories.
According to the different classification of nature and size, it is divided into standard type / general type / special type / special type refractories, etc.
