1, aluminum-silicon refractory bricks, typically represented by clay refractory bricks and high alumina refractory bricks, clay bricks are mainly composed of mullite (25% ~ 50%), glass phase (25% ~ 60%) and quartz and quartz (up to 30%). Usually hard clay as a material, pre-calcined mature material, and then with soft clay, semi-dry or plastic molding method, the temperature of 1300 ~ 1400 degree burned clay brick products, but also able to add a small number of water glass, phosphoric acid and other combining agents made of non-fired refractory bricks.

2, magnesium series refractory bricks, refers to alkaline oxides such as Mg0 as the main component of the refractory products, typical refractory bricks are magnesium bricks and magnesium chromium bricks.

3, carbon refractory bricks, carbon refractory bricks are made of carbon or carbon compounds to contain different shapes of carbon as the main component of the refractory brick products, typical products are carbon bricks, graphite crucible products.

4, zirconium-containing refractory bricks, belonging to a genus of acidic products, is a natural zircon sand (ZrSiO4) as the raw material for the products. Zirconium refractory bricks are different from aluminum-silicon refractory bricks and carbon series of refractory bricks, its slag resistance is good, thermal expansion rate is small, thermal conductivity with the increase in temperature and reduce the loaded softening temperature is high, wear-resistant strength, good resistance to thermal shock, and has now become an important product in various industrial fields.

5, silicon refractory bricks, refers to the SiO2 content of more than 90% of the refractory bricks, it is the primary type of acid refractory bricks, it is mainly used for masonry coke ovens, but also used for a variety of glass, ceramics, charcoal calciner, refractory bricks, thermal kilns and other load-bearing parts of the vault, in the hot blast stove of the high temperature load-bearing parts, but not suitable for use in the 600 degree and the temperature fluctuations in the thermal equipment.

6, silicon carbide refractory bricks, silicon carbide (SiC) as the material for the production of high-grade refractory bricks refractory materials, abrasion and corrosion resistance, high-temperature strength, high thermal conductivity, coefficient of linear expansion is small, good thermal shock resistance.
