High alumina refractory materials feature high Al2O3 content, so its high temperature properties are better than fire clay Changxing refractory materials.
The slag resistance of high alumina bricks increases with the increase of Al2O3 content and the pure corundum products has the nest slag resistance.

Chemical composition

According to the content and function of each component, the chemical composition of refractory can be divided into two parts which are principal components and sub components.

1. Principal components: it is the component of Changxing refractory material matrix in refractory products and is the basics of refractory material. Its nature and quantity directly determine the characteristic of products. Its main composition can be oxide and can also be an element or a non oxide compound.According to the chemical property of the principal components, Changxing refractory material can be classified to acidic refractory, neutral refractory, and alkaline refractory.

2. Impurity components: there are a certain amount of impurities in refractory materials or raw materials.

3. Adding components: mineralization agent, stabilizer, and sintering agent, etc.
