The classification of refractory materials
According to the different chemical properties, refractories
can be divided into acidic, alkaline and neutral. The acidic refractory material
is composed of silicon oxide, This
part of refractory material is easy to react with other alkaline substances in high temperature environment, such as: alkaline refractories, alkaline solution etc. Alkaline
refractory raw materials are mostly magnesium oxide and calcium oxide. Like acidic refractory materials, it is easy to react with other acidic refractory materials at high
temperatures. For example: acidic solutions, acidic refractories, etc. Compared with the first two chemical refractory materials, neutral refractory materials can still maintain
their stability in high temperature environments and rarely react with other substances.
