Using synthetic abrasives (white fused alumina, chrome corundum, black silicon carbide, green silicon carbide) as raw materials, various ceramic products such as ceramic crucibles and ceramic membranes are made by adding different binders and processing them at high temperatures.
For example, ceramic membranes require white fused alumina micro-powders in various grits like 600#, 800#, 1000#, 1500#, 2000#, 3000#, 4000#, and 6000#. Different particle sizes result in different permeability rates, achieving the desired filtration effect. Additionally, the appearance of white fused alumina must meet high standards of purity, with no black spots, as these can cause pits when fired at high temperatures, affecting both aesthetics and functionality. Our white fused alumina is available in a full range of models, with high purity and no black spots, perfectly meeting customer needs.
White fused alumina is produced from high-quality aluminum oxide powder, refined and crystallized through electric arc smelting.
Pink aluminum oxide or ruby aluminum oxide is made by aluminum oxide powder, which is electrically fused at high-temperature by adding appropriate amount of chromium oxide, etc.
Black silicon carbide is produced by smelting quartz sand, petroleum coke (or coal coke), wood chips, and other raw materials in a resistance furnace.
Green silicon carbide is made from petroleum coke and high-quality silica, with salt added as an additive, and refined in a high-temperature resistance furnace.
Metallurgy refers to the process and techniques of extracting metals or metal compounds from minerals and processing them into metal materials with specific properties through various methods.
Investment casting involves melting solid metal into a liquid state and pouring it into a mold to form a specific shape, which then solidifies.
Refractory materials are inorganic, non-metallic materials that can withstand high temperatures and meet usage requirements in high-temperature environments.
Surface finishing is a process that treats the surface of a work piece using compressed air to create a high-speed jet that propels abrasives (such as white fused alumina, brown fused alumina, garnet, glass beads, etc.) At high speed onto the work piece.
Fused Alumina
Use in many different industries such as abrasives, refractories, sandblasting etc.
