所謂組(zu)成(cheng)(cheng)耐火質(zhi)料，就是將兩種(zhong)或(huo)兩種(zhong)以(yi)上的(de)天(tian)然礦藏(zang)質(zhi)料或(huo)化工(gong)質(zhi)料或(huo)廢(fei)棄物(wu)，通過配料、粉碎，磨細，混(hun)合，成(cheng)(cheng)型，煅燒或(huo)電(dian)熔(rong)等工(gong)藝(yi)進程，合成(cheng)(cheng)鎂鐵鈣(gai)砂制取必定化學(xue)礦藏(zang)組(zu)成(cheng)(cheng)和物(wu)理性能的(de)耐火質(zhi)料。組(zu)成(cheng)(cheng)耐火質(zhi)料的(de)品種(zhong)繁復，組(zu)成(cheng)(cheng)辦(ban)法多種(zhong)多樣，大(da)體簡略(lve)介紹：

 純化(hua)工(gong)質料之(zhi)間組成(cheng)耐(nai)火質料，如用(yong)工(gong)業(ye)氧化(hua)鋁與(yu)(yu)鈦白粉(fen)組成(cheng)鈦酸鋁;鋁粉(fen)與(yu)(yu)氮(dan)氣化(hua)合組成(cheng)AIN(氮(dan)化(hua)鋁);工(gong)業(ye)氧化(hua)鋁與(yu)(yu)高純超細的氮(dan)化(hua)鋁粉(fen)組成(cheng)Alon(阿隆(long));用(yong)輕(qing)質碳酸鈣與(yu)(yu)工(gong)業(ye)氧化(hua)鋁，按CA6的CaO與(yu)(yu)Al?O?的化(hua)學計量比例配料，組成(cheng)六鋁酸鈣;用(yong)鈦白粉(fen)和(he)金屬鋁粉(fen)在流動氨氣效(xiao)果下，原位(wei)生成(cheng)Al?O?-TiN復相資料等。

所謂組成(cheng)耐火(huo)質料(liao)，就(jiu)是將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以上的天然礦藏(zang)質料(liao)或(huo)化工質料(liao)或(huo)廢棄物，通過配料(liao)、粉碎，磨細，混(hun)合，成(cheng)型，煅(duan)燒或(huo)電熔(rong)等工藝進(jin)程，合成(cheng)鎂鐵(tie)鈣砂制(zhi)取必定化學礦藏(zang)組成(cheng)和物理性能的耐火(huo)質料(liao)。
