White Fused Alumina History and Features
White fused alumina History and Features The traditional white fused aluminum powder is prepared by smelting the raw materials in an electric arc furnace at high temperature, processing, finely smashing, and then performing hydraulic classification and dividing them into white corundum powder of different particle sizes. Nowadays, white corundum powder is also called sintered white alumina powder. It is made by forming powdered raw materials and heating them at a temperature lower than their melting point to make them adhere to each other, bond, eutectic, and reheat under the action of additives. White corundum is one of artificial abrasive. It mainly contains aluminum oxide and a small amount of iron oxide, silicon oxide, and other components. The fused alumina produced by YuFa Group is dense, high in hardness, and shaped like sharp angles. It is suitable for manufacturing ceramics, resin-consolidated abrasive tools, grinding, polishing, sandblasting, precision high-grade refractory materials. White fused corundum crystal size is small and impact resistant. It is processed and broken by a self-grinding machine. The particles are mostly spherical particles. The surface is dry and clean. It is easy to combine with a binder. It is suitable for various high-end products, crafts, or hardware. The surface...
