白剛玉是以**氧化鋁粉為原料，在2050℃高溫下熔煉而成，它具有純度高、自銳性好、磨削時(shí)發(fā)熱量小、耐酸堿、高溫穩(wěn)定性好、氣孔率低等優(yōu)點(diǎn)。

電熔白剛玉是生產(chǎn)中**不定型和定型耐火材料的主要原料，常用于鋼包澆注料、鐵溝料、耐火噴補(bǔ)料等不定型耐火制品；在定型耐材中，它主要用在剛玉磚、剛玉莫來石質(zhì)匣缽、精煉用剛玉多孔塞磚、整體噴槍、煉鋼連鑄三大件、超高溫工業(yè)窯爐內(nèi)襯等剛玉制品。它又是磨料磨具行業(yè)**原料，主要用在砂輪磨具、拋光研磨行業(yè)，在軍工、造船、玻璃、**、航天、光學(xué)儀器、核能等行業(yè)有廣泛的前途。
