所謂組成(cheng)耐(nai)火(huo)質料，就是將兩種(zhong)(zhong)或兩種(zhong)(zhong)以上的天然礦藏質料或化(hua)工(gong)質料或廢棄物，通過配料、粉碎，磨細，混(hun)合(he)，成(cheng)型，煅(duan)燒或電熔等(deng)工(gong)藝進程，合(he)成(cheng)鎂鐵鈣砂制(zhi)取必定化(hua)學礦藏組成(cheng)和物理性能的耐(nai)火(huo)質料。組成(cheng)耐(nai)火(huo)質料的品種(zhong)(zhong)繁復，組成(cheng)辦法(fa)多種(zhong)(zhong)多樣，大體(ti)簡略介紹：

 純化(hua)(hua)(hua)工質料(liao)(liao)之間組成(cheng)耐(nai)火質料(liao)(liao)，如用工業(ye)(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)與(yu)(yu)鈦白粉(fen)組成(cheng)鈦酸鋁(lv);鋁(lv)粉(fen)與(yu)(yu)氮(dan)氣化(hua)(hua)(hua)合組成(cheng)AIN(氮(dan)化(hua)(hua)(hua)鋁(lv));工業(ye)(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)與(yu)(yu)高(gao)純超細(xi)的(de)氮(dan)化(hua)(hua)(hua)鋁(lv)粉(fen)組成(cheng)Alon(阿隆);用輕質碳酸鈣與(yu)(yu)工業(ye)(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)，按(an)CA6的(de)CaO與(yu)(yu)Al?O?的(de)化(hua)(hua)(hua)學(xue)計(ji)量比例配料(liao)(liao)，組成(cheng)六鋁(lv)酸鈣;用鈦白粉(fen)和金(jin)屬(shu)鋁(lv)粉(fen)在流動氨氣效果(guo)下(xia)，原位生成(cheng)Al?O?-TiN復相資料(liao)(liao)等(deng)。

所(suo)謂組成耐火質料(liao)(liao)，就是將兩種或(huo)兩種以上的(de)天(tian)然礦藏質料(liao)(liao)或(huo)化(hua)工(gong)質料(liao)(liao)或(huo)廢(fei)棄物，通(tong)過配料(liao)(liao)、粉碎，磨細，混(hun)合(he)，成型(xing)，煅燒或(huo)電熔等工(gong)藝進程，合(he)成鎂鐵鈣(gai)砂制取必定化(hua)學(xue)礦藏組成和(he)物理性能的(de)耐火質料(liao)(liao)。
