白刚玉是以**氧化铝粉为原料，在2050℃高温下熔炼而成，它具有纯度高、自锐性好、磨削时发热量小、耐酸碱、高温稳定性好、气孔率低等优点。
电熔白刚玉是生产中**不定型和定型耐火材料的主要原料，常用于钢包浇注料、铁沟料、耐火喷补料等不定型耐火制品；在定型耐材中，它主要用在刚玉砖、刚玉莫来石质匣钵、精炼用刚玉多孔塞砖、整体喷枪、炼钢连铸三大件、超高温工业窑炉内衬等刚玉制品。它又是磨料磨具行业**原料，主要用在砂轮磨具、抛光研磨行业，在军工、造船、玻璃、**、航天、光学仪器、核能等行业有广泛的前途。

Ashe mairaw material for producing middle/high-class moolithicrefractories orformedefractory products, white fused corundum isused primarily for ladle castable, irorunner castable gunningrefractory or other moolithicefractory products. As for formedrefractories, it’schiefly used iproducing corundum bricks,corundum-mullite saggers,efining-used corundum porous plugbricks, iegral blowing lance,hree-piece for steel makingcon-casting production, ultra-hightemperature industrial fuacelining, and other corundum products.
