Polycrystalline corundum

Polycrystalline corundum
Polycrystalline corundum is produced by adding new elements to the black corundum manufacturing process, thereby optimizing its primary crystal structure. It exhibits a brown‑black color and is characterized by high hardness, excellent toughness, and superior self‑sharpening properties. Polycrystalline corundum retains the advantageous features of black corundum—such as outstanding self‑sharpening, exceptional sharpness, low heat generation, and a highly polished surface—while significantly enhancing its durability.

Black Corundum

Black Corundum
Black corundum is an energy‑saving, environmentally friendly alternative wear‑resistant material produced by high‑temperature smelting in an electric arc furnace, using high‑iron alumina or high‑alumina bauxite combined with high‑alumina iron ore. After melting and subsequent cooling, it yields a gray‑black crystalline product whose principal mineral phases are α‑Al₂O₃ and ferrospinel.

Black silicon carbide

Black silicon carbide
Black silicon carbide is produced by high‑temperature smelting in an electric resistance furnace, using raw materials such as quartz sand and petroleum coke (or coal coke). Due to its stable chemical properties, high thermal conductivity, low coefficient of thermal expansion, and excellent wear resistance, silicon carbide is used not only as an abrasive but also as a refractory material.

Calcined Brown Corundum

Calcined Brown Corundum
Calcined brown corundum is produced by processing conventional brown corundum at high temperatures to remove or volatilize impurities. As a result, it becomes purer and develops a rougher surface, making it more hydrophilic. Moreover, microcracks formed during crushing further enhance its toughness and strength.

Plated White Corundum

Plated White Corundum
Plated‑coated white corundum is a new type of corundum material, formed by high‑temperature calcination of white corundum. It retains the sharpness of ordinary white corundum while enhancing toughness, exhibits no dark streaks internally, and offers improved compressive strength. Moreover, after coating with metal salts and ceramics, it becomes more adhesive. Cutting discs made from this material are sharper and more durable.
