所謂組(zu)(zu)(zu)成(cheng)耐火(huo)(huo)質(zhi)料(liao)(liao)，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以上的天然礦(kuang)藏質(zhi)料(liao)(liao)或(huo)(huo)化(hua)工質(zhi)料(liao)(liao)或(huo)(huo)廢棄物，通過配料(liao)(liao)、粉碎，磨細，混合，成(cheng)型，煅燒或(huo)(huo)電熔等工藝進程，合成(cheng)鎂鐵鈣砂制(zhi)取必定化(hua)學礦(kuang)藏組(zu)(zu)(zu)成(cheng)和物理性能的耐火(huo)(huo)質(zhi)料(liao)(liao)。組(zu)(zu)(zu)成(cheng)耐火(huo)(huo)質(zhi)料(liao)(liao)的品種(zhong)繁復，組(zu)(zu)(zu)成(cheng)辦法多(duo)種(zhong)多(duo)樣，大體簡略介紹：

 純化(hua)(hua)工(gong)(gong)質(zhi)料之間組成(cheng)(cheng)耐火質(zhi)料，如用(yong)工(gong)(gong)業(ye)(ye)氧化(hua)(hua)鋁(lv)(lv)與(yu)鈦(tai)白粉(fen)組成(cheng)(cheng)鈦(tai)酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)與(yu)氮氣化(hua)(hua)合組成(cheng)(cheng)AIN(氮化(hua)(hua)鋁(lv)(lv));工(gong)(gong)業(ye)(ye)氧化(hua)(hua)鋁(lv)(lv)與(yu)高純超細的氮化(hua)(hua)鋁(lv)(lv)粉(fen)組成(cheng)(cheng)Alon(阿隆);用(yong)輕質(zhi)碳酸鈣與(yu)工(gong)(gong)業(ye)(ye)氧化(hua)(hua)鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)學計量比例配料，組成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦(tai)白粉(fen)和(he)金屬鋁(lv)(lv)粉(fen)在(zai)流動氨氣效果下，原位生成(cheng)(cheng)Al?O?-TiN復相資料等。

所謂組成耐(nai)火質(zhi)料(liao)，就是(shi)將兩種(zhong)或(huo)兩種(zhong)以上的天然礦(kuang)藏(zang)質(zhi)料(liao)或(huo)化工(gong)質(zhi)料(liao)或(huo)廢棄(qi)物，通過(guo)配料(liao)、粉碎，磨細(xi)，混合，成型，煅燒或(huo)電熔(rong)等(deng)工(gong)藝進程(cheng)，合成鎂鐵鈣砂制(zhi)取必定化學礦(kuang)藏(zang)組成和物理性(xing)能的耐(nai)火質(zhi)料(liao)。
