White fused alumina is made of industrial aluminum oxide, fused at 2250 temperature and formed in white color. Our white fused alumina has advantage of high hardness, uniform particle size and dense texture and high temperature resistance.
Brown corundum is brown, made of bauxite and coke ( anthracite ) as main raw materials smelted at 2300℃ in a dumping furnace. Its main chemical components are Al2O3 and TiO2，and it also contains a small amount of SiO2 and Fe2O3 etc.
Black fused alumina is a kind of flexible abrasive material, which is made of high iron bauxite fused at high temperature in an electric arc furnace and then cool to produce a gray-black crystal with a-Al2O3 and iron spinel as the main mineral phases.
Pink fused alumina, also called chromium fused alumina, is a kind of alumina with little Cr2O3. Compared with brown fused alumina, pink fused aluminium oxide has a higher hardness and lower toughness.
Glass Beads are made of hardened spherical soda lime glass and are a multi-faceted and commonly used media. Cost effective, ideal where metal contamination is not allowed, and often used to peen difficult to reach part areas
Tabular Alumina is a high purity alumina essentially processed by high quality alumina after sintering and fusing.
Made from high quality alumina and light-burned magnesia in electric arc furnace. The fused magnesia-alumina spinel has outstanding refractoriness, good erosion resistance, high anti-corrosion, high resistance against flaking, good thermal stability, high temperature resistance, high slag-resistance, good thermal shock resistance, etc. It also has high true density, low water absorption, low thermal expansion coefficient ,good thermal stability and good thermal shock resistance.
Mullite is a high-quality refractory raw material, and this type of mineral is relatively rare. Mullite is a mineral produced by aluminosilicates at high temperatures. Mullite is formed when aluminosilicates are artificially heated. Natural mullite crystals are slender, needle-like and radially clustered. Mullite is used to produce high temperature refractories. Mostly used as thermal barrier coatings in C / C composites, it is widely used. The mullite AI2O3-SiO2 elementary system is a stable binary solid solution under normal pressure. The natural mullite with the chemical formula of AI2O3-SiO2 is very few. It is usually artificially synthesized by sintering or electrofusion.
Black silicon carbide is black, brittle and sharp, and has good thermal conductivity and electrical conductivity. It takes petroleum coke and high quality silicon as raw materials, adds salt as additive, and is fused through the electric resistance furnace at more than 2200˚C temperature.
Green silicon carbide is a non-metallic mineral product produced by high quality quartz sand and petroleum coke at the high temperature over 1800℃ in the electric resistance furnace.
