According to the purposes are divided into iron and steel industry, non-ferrous metal industry, petrochemical industry, silicate industry, power industry, waste incineration melting furnace refractory material. 3. According to the mineral composition is divided into silicon oxide, aluminum silicate, magnesite, dolomite, olivine, carbon, containing zirconium refractory materials. In mechanical and electrical engineering, for example, all kinds of refractory brick and masonry of refractory material is mainly used for various types of furnaces project, various types of boiler furnace wall masonry, various types of smelting furnace masonry, various types of kiln lining, etc. Magnesia refractory materials, for example, is magnesium stone as raw materials, the Israeli magnesium stone as the main mineral composition, periclase content in 80% to 85% or more of the refractory material, belongs to the basic refractory, has good resistance to alkali erosion ability, high refractoriness, steel-making alkaline converter, electric furnace, cupola, and many of the most widely used in non-ferrous metal melting furnace of fire a class of important refractory material. (4) ceramics 1. The characteristics of the ceramic Ceramics with clay and other silicate minerals as raw material, through powder processing, molding, sintering process, such as with a hard, not burning, not rust, can withstand the light, pressure and other excellent properties. Ceramic hardness is very high, but the brittleness is very large. 2. The classification of ceramic According to the sources of raw materials can be divided into general and special ceramic; Ordinary ceramic is natural silicate minerals as the main raw material, such as clay, quartz, feldspar, etc., the main products are construction ceramics, electrical insulating ceramics, chemical ceramics, porous ceramics, etc.; Special ceramics is a high purity synthetic compounds as the main raw material of synthetic compounds, such as aluminum oxi
