所謂組成(cheng)(cheng)耐火(huo)質(zhi)料，就是將兩種或(huo)兩種以上的(de)天然礦(kuang)藏質(zhi)料或(huo)化工(gong)質(zhi)料或(huo)廢棄物，通(tong)過配料、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅(duan)燒或(huo)電(dian)熔等工(gong)藝進(jin)程，合(he)成(cheng)(cheng)鎂鐵鈣砂制取必(bi)定化學礦(kuang)藏組成(cheng)(cheng)和物理性能的(de)耐火(huo)質(zhi)料。組成(cheng)(cheng)耐火(huo)質(zhi)料的(de)品種繁復(fu)，組成(cheng)(cheng)辦法多種多樣，大體簡略介紹：

 純化(hua)(hua)(hua)工(gong)質料(liao)(liao)(liao)之間組(zu)成(cheng)(cheng)耐火(huo)質料(liao)(liao)(liao)，如用工(gong)業氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)與鈦(tai)(tai)白粉組(zu)成(cheng)(cheng)鈦(tai)(tai)酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉與氮(dan)氣化(hua)(hua)(hua)合(he)組(zu)成(cheng)(cheng)AIN(氮(dan)化(hua)(hua)(hua)鋁(lv)(lv));工(gong)業氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)與高純超細(xi)的(de)(de)氮(dan)化(hua)(hua)(hua)鋁(lv)(lv)粉組(zu)成(cheng)(cheng)Alon(阿隆);用輕質碳酸(suan)鈣與工(gong)業氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)，按(an)CA6的(de)(de)CaO與Al?O?的(de)(de)化(hua)(hua)(hua)學(xue)計量比例配料(liao)(liao)(liao)，組(zu)成(cheng)(cheng)六鋁(lv)(lv)酸(suan)鈣;用鈦(tai)(tai)白粉和金屬(shu)鋁(lv)(lv)粉在流動(dong)氨(an)氣效果下，原位生成(cheng)(cheng)Al?O?-TiN復相資料(liao)(liao)(liao)等。

所(suo)謂組成(cheng)耐火質料(liao)，就是將兩(liang)種或兩(liang)種以上的天然礦藏質料(liao)或化(hua)(hua)工質料(liao)或廢(fei)棄物，通過配料(liao)、粉碎，磨細(xi)，混合，成(cheng)型，煅燒或電熔等工藝進程，合成(cheng)鎂鐵鈣砂制取必定化(hua)(hua)學礦藏組成(cheng)和物理性能的耐火質料(liao)。
