Graphite Powder
Graphite powder is soft and dark gray. In the absence of oxygen, its melting point is above 3000 ℃, and it is one of the most temperature-resistant minerals. The chemical properties of graphite powder are relatively stable at room temperature, and are insoluble in water, dilute acids, dilute alkalis and organic solvents. The material has high temperature resistance and conductivity, and can be used as refractory materials, conductive materials, and wear-resistant lubricating materials.
Fused Silica
Fused Silica is made of high purity quartz sand by electrically fused in electric arc furnaces, then the crystalline quartz sand transformed into amorphous silicon dioxide.

Black /Green Silicon Carbide
Silicon carbide is made by high temperature smelting of raw materials such as quartz sand, petroleum coke (or coal coke), wood chips (salt is needed to produce green silicon carbide) in a resistance furnace. At present, silicon carbide is divided into black silicon carbide and green silicon carbide, both of which are hexagonal crystals, with a specific gravity of 3.20-3.25 and a microhardness of 2840-3320kg/mm2.

Mullite Brick
Mullite brick refers to a high alumina refractory material with mullite as the main crystal phase. Generally, the alumina content is between 65% and 75%.Mullite bricks have high refractoriness, which can reach above 1790℃. Mullite bricks are divided into sintered mullite bricks and fused mullite bricks.

Precast Coke Oven Door
The surface of pre-cast refractory door is made of composite ceramic material. Pre-cast refractory is shaped by high frequency vibration. The unformed material has low porosity, high density and good uniformity. There is crystalline ceramic refractory adhere the pre-cast surface, which have high strength, good abrasion resistance and corrosion resistance. It has been reduced the physical damage during the operation and tar and other chemicals erosion to the refractory.
