company news about The main chemical elements of refractory materials

The principal component in refractory materials refers to the majority of chemical components of the material properties, temperature plays a decisive role in. The performance of refractory material has excellent resistance to high temperature, and many refractory materials have properties, completely or basically depends on principal component. Therefore, the principal component of refractory material, must pay attention. Usually, the refractory material in chemical composition and classification, and for many of the same material refractory material is divided into several levels, are all or mostly according to the kinds of its main components and its content determined. Can be used as a refractory material principal components are high melting point is high lattice energy or decomposition temperature very high element or compound. Asking it to form a stable with the excellent performance of the minerals in the refractory material production or service process in nature reserves, higher and more easy to extract and use. The distribution of more in the earth's crust, can be used as a refractory material principal component are mainly oxide. In addition, there are some carbides, nitrides, silicides and borides, also can be used as the main component of refractory materials.

Now, the main components of refractory material production and widely used is the main Al2O3, BeO, Cr203, MgO, CaO, SiO2, ThO2, TiO2, UO2, ZrO2 and other oxides and SiC, WC, B4C, AIN, Si3N4 carbide
