In the baking process boilers, silica brick volume increases with increasing temperature. Therefore, the silica brick of coke oven is the ideal refractory products. Now the important parts of the large and medium sized of coke oven (such as combustion chamber, ramps and heat accumulation chamber) use the silica brick masonry.
Mullite brick IS characterized by good high temperature resistance and good thermal shock resistance, whick comes into being mullite through calcine with clay, high alumina materials and ceramics. The main applications are: Sulfuric cracking furnace Fibrous glass furnance. Specifications Low permanent linear change on reheating
Since 1977, our company has been providing refractory materials (fire bricks) for industries like glass, ceramic, iron and steel manufacturing plants. At the same time, we have been exporting to many countries in many regions like Europe, Africa, Middle East and North America.
Refractory castable classification: According to its properties and functions, this refractory castable can be classified into insulation refractory castable, high alumina concrete, low cement castable(LCC), steel fiber castable, and so on. Based on the chemical properties, it can be classified into alkaline castable, neutral castable, and acid
Refractory cements and raw materials are hard, heat resistant materials that are suitable for applications that require high temperature strength, wear resistance, electrical or thermal insulation, or other specialized characteristics. Refractory cements are used to patch or line furnaces and bond bricks or joints in high temperature applications.
As the corundum mullite bricks manufacturer from China, Hitech Material offers corundum mullite bricks and the other Al-Si refractory bricks, which are widely used as linings in glass furnace, decomposing furnaces for petroleum, high temperature kiln and petrochemical industry.
High Alumina Fire Bricks, Blocks & Tiles. A firebrick / refractory brick is a shape made from refractory ceramics. It is used in lining furnace kilns, fireboxes and fireplaces. Its primary purpose is to withstand high temperature and also to retain the heat for greater energy efficiency.

Silica-mullite bricks are characterized by good performance of thermal shock resistance, better wear-resistance and spalling resistance. It's a good choice for cement kiln and applied in transition zone, cooling zone and outlet. Classification: GM-1550 1650 1680
Mullite Brick is a kind of High-aluminum refractories that regard the mullite (Al2O3•SiO2) as the main crystal phase. The average alumina content is between 65% and 75%. In addition to mullite mineral composition, which contains lower alumina also contains a small amount of glass and cristobalite; higher alumina containing a small amount of
Fire Clay & High Alumina Bricks. We manufacture and export Fire Clay & High Alumina Bricks. Alumina is an excellent engineering ceramic, offering excellent electrical insulation properties together with high hardness and good wear resistance but relatively low strength and fracture toughness.
Silicon fire brick belongs to silicon refractory materials, silica brick is a kind of quality refractory materials products with over 93% SiO2 content. silicate refractory brick has excellent features of good resistance to acid corrosion, great heat conductivity, high refractoriness under load at over 1620℃. and also silica bricks have fratures of strong acid slag erosion resistance, high
Silica mullite bricks can be used for calcining zone and transition zone in medium and small cement kiln. Silica mullite firebricks are mainly used in roasting furnace or calcinator. Silica mullite refractory bricks are widely used in all kinds of industries of iron & steel, petrochemical, nonferrous metals, machinery, electricity, building and
