所謂(wei)組成(cheng)耐(nai)火質(zhi)料(liao)，就是將兩種(zhong)或兩種(zhong)以上的(de)天然礦藏質(zhi)料(liao)或化工質(zhi)料(liao)或廢棄(qi)物，通過配(pei)料(liao)、粉碎，磨(mo)細，混合，成(cheng)型，煅燒(shao)或電(dian)熔(rong)等工藝(yi)進(jin)程，合成(cheng)鎂鐵鈣砂(sha)制取(qu)必定化學礦藏組成(cheng)和物理性能的(de)耐(nai)火質(zhi)料(liao)。組成(cheng)耐(nai)火質(zhi)料(liao)的(de)品(pin)種(zhong)繁復，組成(cheng)辦法(fa)多種(zhong)多樣，大體簡略介(jie)紹：

 純化(hua)(hua)(hua)(hua)工(gong)質料之間組成耐火質料，如(ru)用工(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)(lv)(lv)與(yu)鈦(tai)白粉組成鈦(tai)酸鋁(lv)(lv)(lv);鋁(lv)(lv)(lv)粉與(yu)氮(dan)氣化(hua)(hua)(hua)(hua)合組成AIN(氮(dan)化(hua)(hua)(hua)(hua)鋁(lv)(lv)(lv));工(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)(lv)(lv)與(yu)高(gao)純超細的氮(dan)化(hua)(hua)(hua)(hua)鋁(lv)(lv)(lv)粉組成Alon(阿隆);用輕質碳酸鈣與(yu)工(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)(hua)鋁(lv)(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)(hua)(hua)學計(ji)量比例配料，組成六鋁(lv)(lv)(lv)酸鈣;用鈦(tai)白粉和金(jin)屬鋁(lv)(lv)(lv)粉在流(liu)動(dong)氨(an)氣效果下，原位生成Al?O?-TiN復相資料等。
