所(suo)謂組成(cheng)耐火質(zhi)料，就是將兩(liang)種(zhong)或兩(liang)種(zhong)以上的天然礦(kuang)藏質(zhi)料或化(hua)工質(zhi)料或廢棄物，通過(guo)配料、粉(fen)碎，磨(mo)細，混合，成(cheng)型，煅燒或電(dian)熔等工藝進程，合成(cheng)鎂鐵(tie)鈣砂(sha)制取必定化(hua)學礦(kuang)藏組成(cheng)和物理性能的耐火質(zhi)料。組成(cheng)耐火質(zhi)料的品種(zhong)繁復(fu)，組成(cheng)辦法(fa)多種(zhong)多樣，大體簡略介紹：

 純(chun)化(hua)(hua)工(gong)(gong)(gong)質料(liao)之間組(zu)成(cheng)(cheng)耐火(huo)質料(liao)，如(ru)用(yong)工(gong)(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)與鈦白粉(fen)組(zu)成(cheng)(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)與氮氣化(hua)(hua)合組(zu)成(cheng)(cheng)AIN(氮化(hua)(hua)鋁(lv)(lv));工(gong)(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)與高純(chun)超細的(de)氮化(hua)(hua)鋁(lv)(lv)粉(fen)組(zu)成(cheng)(cheng)Alon(阿隆);用(yong)輕質碳酸鈣與工(gong)(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)，按(an)CA6的(de)CaO與Al?O?的(de)化(hua)(hua)學(xue)計量比(bi)例配料(liao)，組(zu)成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白粉(fen)和金屬鋁(lv)(lv)粉(fen)在流動氨氣效果下，原位生(sheng)成(cheng)(cheng)Al?O?-TiN復相資料(liao)等。

所謂組(zu)成耐(nai)火(huo)(huo)質(zhi)(zhi)料(liao)，就是(shi)將兩種或(huo)兩種以上的(de)(de)天然礦(kuang)藏質(zhi)(zhi)料(liao)或(huo)化(hua)工質(zhi)(zhi)料(liao)或(huo)廢棄物，通過配料(liao)、粉碎，磨細，混合，成型(xing)，煅燒或(huo)電熔等工藝(yi)進程，合成鎂鐵鈣砂制取(qu)必定化(hua)學礦(kuang)藏組(zu)成和物理性能的(de)(de)耐(nai)火(huo)(huo)質(zhi)(zhi)料(liao)。
