所謂組(zu)成(cheng)(cheng)耐(nai)火質料，就是將兩(liang)種(zhong)或兩(liang)種(zhong)以上的(de)天然礦(kuang)藏質料或化工(gong)質料或廢棄物，通過配料、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅燒或電熔等工(gong)藝進程，合(he)成(cheng)(cheng)鎂鐵鈣(gai)砂(sha)制(zhi)取必定(ding)化學礦(kuang)藏組(zu)成(cheng)(cheng)和(he)物理性能的(de)耐(nai)火質料。組(zu)成(cheng)(cheng)耐(nai)火質料的(de)品種(zhong)繁復(fu)，組(zu)成(cheng)(cheng)辦法(fa)多種(zhong)多樣，大(da)體簡略(lve)介紹：

 純化(hua)(hua)(hua)工(gong)(gong)(gong)質(zhi)料之間(jian)組成(cheng)耐(nai)火(huo)質(zhi)料，如用工(gong)(gong)(gong)業氧化(hua)(hua)(hua)鋁(lv)與(yu)(yu)鈦白(bai)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(gong)(gong)(gong)業氧化(hua)(hua)(hua)鋁(lv)與(yu)(yu)高(gao)純超(chao)細的(de)(de)(de)氮(dan)化(hua)(hua)(hua)鋁(lv)粉(fen)組成(cheng)Alon(阿(a)隆);用輕質(zhi)碳酸鈣(gai)與(yu)(yu)工(gong)(gong)(gong)業氧化(hua)(hua)(hua)鋁(lv)，按CA6的(de)(de)(de)CaO與(yu)(yu)Al?O?的(de)(de)(de)化(hua)(hua)(hua)學計量比例配料，組成(cheng)六鋁(lv)酸鈣(gai);用鈦白(bai)粉(fen)和金屬鋁(lv)粉(fen)在流動氨氣效果下，原位(wei)生成(cheng)Al?O?-TiN復相(xiang)資料等。

所謂(wei)組成耐(nai)火(huo)質(zhi)料(liao)(liao)，就(jiu)是將兩種或兩種以上的天(tian)然礦藏(zang)質(zhi)料(liao)(liao)或化工質(zhi)料(liao)(liao)或廢棄物，通(tong)過配料(liao)(liao)、粉碎，磨細，混合，成型，煅(duan)燒或電(dian)熔等工藝進程(cheng)，合成鎂鐵(tie)鈣砂制(zhi)取必定化學礦藏(zang)組成和(he)物理(li)性(xing)能(neng)的耐(nai)火(huo)質(zhi)料(liao)(liao)。
