所謂組成耐(nai)火(huo)(huo)質(zhi)料，就是(shi)將兩種(zhong)或兩種(zhong)以上的天然礦藏質(zhi)料或化工質(zhi)料或廢棄(qi)物(wu)，通(tong)過配料、粉碎(sui)，磨(mo)細(xi)，混(hun)合，成型，煅燒或電熔等(deng)工藝進程，合成鎂鐵(tie)鈣砂(sha)制取必定化學(xue)礦藏組成和物(wu)理性能的耐(nai)火(huo)(huo)質(zhi)料。組成耐(nai)火(huo)(huo)質(zhi)料的品種(zhong)繁復(fu)，組成辦法多種(zhong)多樣，大體簡略介紹(shao)：

 純化(hua)(hua)工(gong)質料(liao)之間(jian)組(zu)(zu)成耐火(huo)質料(liao)，如用(yong)(yong)工(gong)業氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)(lv)與(yu)(yu)鈦(tai)白粉組(zu)(zu)成鈦(tai)酸(suan)(suan)鋁(lv)(lv)(lv)(lv)(lv);鋁(lv)(lv)(lv)(lv)(lv)粉與(yu)(yu)氮(dan)(dan)氣(qi)化(hua)(hua)合組(zu)(zu)成AIN(氮(dan)(dan)化(hua)(hua)鋁(lv)(lv)(lv)(lv)(lv));工(gong)業氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)(lv)與(yu)(yu)高純超細的氮(dan)(dan)化(hua)(hua)鋁(lv)(lv)(lv)(lv)(lv)粉組(zu)(zu)成Alon(阿隆(long));用(yong)(yong)輕質碳酸(suan)(suan)鈣與(yu)(yu)工(gong)業氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)(lv)，按(an)CA6的CaO與(yu)(yu)Al?O?的化(hua)(hua)學計量(liang)比例配料(liao)，組(zu)(zu)成六(liu)鋁(lv)(lv)(lv)(lv)(lv)酸(suan)(suan)鈣;用(yong)(yong)鈦(tai)白粉和金(jin)屬(shu)鋁(lv)(lv)(lv)(lv)(lv)粉在流動氨氣(qi)效果(guo)下，原(yuan)位生成Al?O?-TiN復相資料(liao)等。
