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。
White fused alumina is made fromexcellent industrial alumina and melted in arc furnaces at hightemperature of 2050℃.It is featured by high purity, goodself-sharpening, low grinding heat output, acid-alkali andcorrosion resistance, good stability at high temperature, and lowporosity, etc.
As the main raw material for producing middle/high-class monolithicrefractories or formed refractory products, white fused corundum isused primarily for ladle castable, iron runner castable gunningrefractory or other monolithic refractory products. As for formedrefractories, it’s chiefly used in producing corundum bricks,corundum-mullite saggers, refining-used corundum porous plugbricks, integral blowing lance, three-piece for steel makingcon-casting production, ultra-high temperature industrial furnacelining, and other corundum products. It’s also the high-quality rawmaterial in abrasives industries, mainly used for producinggrinding wheel, grinding and polishing tools, as well as the mostpromising material with bound less prospects used in military, shipbuilding, glass making, aerospace,optical-instrument-manufacturing, nuclear power plants constructionand other industries. 白刚玉段砂是指1-0mm,3-1mm,5-3mm,8-5mm,5-10mm,10-20mm……主要用作耐火材料等行业，另外还有8-16mesh，16-30mesh……粒度砂又称为号砂，有F12~F220，如F12，F30，F54，F90，F100，F220等，主要用于磨料等行业。 16-30mesh 1-0mm 1-3mm 5-3mm 5-8mm
