从China供应商批发进口Brown Fused Alumina — FOB条款

The common name for a brown fused alumina is also called the emery, are made of alumina, carbon materials, scrap iron three kinds of raw materials in the electric furnace melting reduction brown alundum, made by reason of brown fused alumina. Brown fused alumina is mainly chemical composition is AL2O3, and its content in 94.5% 94.5%, the other contains a small amount of Fe, Si, Ti, etc. Brown fused alumina is mainly divided into three, brown fused alumina is one of the best level, followed by secondary and tertiary, and the quality standards of brown fused alumina is mainly to see the content of AL2O3 and content in more than 95% for brown fused alumina, which is often said 95 brown fused alumina. Secondary corundum and tertiary corundum content drops, quality also decreases. Brown fused alumina colour can see colors to distinguish, because of the brown fused alumina containing Fe elements (iron), Fe element is red-brown, so brown fused alumina appears as tan, can see color to identify the level and quality of brown fused alumina. Brown corundum sand with hydraulic careful screening, mechanical processing, screening and classifying the grinding materials, mainly used for grinding glass products, industrial cleaning and water cut, etc. On silicon chips, precision instrument, glass, ceramic, stone, leather, metal parts can improve smoothness and sandblasting cutting, is a manufacturer of grinding wheel, emery cloth, sand must be raw materials, can be used as building highway pavement, airport runway, wear-resisting rubber good wear resistant material. Brown fused alumina with high purity, good crystallization, strong liquidity, low linear expansion coefficient, enterprise production practice verification, the product in the process of application of blasting, powder, no crack characteristics, make it become the best in the brown just the quality of the jade of refractory aggregate and filling material .
