所謂組(zu)成耐火(huo)質(zhi)(zhi)料，就(jiu)是將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以上的天然礦藏質(zhi)(zhi)料或(huo)化工質(zhi)(zhi)料或(huo)廢棄(qi)物(wu)(wu)，通(tong)過配料、粉碎，磨細，混合，成型，煅(duan)燒或(huo)電熔(rong)等工藝進程，合成鎂鐵鈣砂制取必定化學礦藏組(zu)成和物(wu)(wu)理性能的耐火(huo)質(zhi)(zhi)料。組(zu)成耐火(huo)質(zhi)(zhi)料的品種(zhong)繁(fan)復(fu)，組(zu)成辦法多(duo)種(zhong)多(duo)樣，大體簡略介紹：

 純化(hua)(hua)工(gong)質(zhi)(zhi)料之間組(zu)(zu)成耐(nai)火質(zhi)(zhi)料，如用工(gong)業氧化(hua)(hua)鋁(lv)(lv)(lv)與(yu)(yu)鈦白粉(fen)(fen)組(zu)(zu)成鈦酸(suan)鋁(lv)(lv)(lv);鋁(lv)(lv)(lv)粉(fen)(fen)與(yu)(yu)氮氣化(hua)(hua)合組(zu)(zu)成AIN(氮化(hua)(hua)鋁(lv)(lv)(lv));工(gong)業氧化(hua)(hua)鋁(lv)(lv)(lv)與(yu)(yu)高純超細的氮化(hua)(hua)鋁(lv)(lv)(lv)粉(fen)(fen)組(zu)(zu)成Alon(阿隆(long));用輕質(zhi)(zhi)碳(tan)酸(suan)鈣與(yu)(yu)工(gong)業氧化(hua)(hua)鋁(lv)(lv)(lv)，按CA6的CaO與(yu)(yu)Al?O?的化(hua)(hua)學計量比例配料，組(zu)(zu)成六鋁(lv)(lv)(lv)酸(suan)鈣;用鈦白粉(fen)(fen)和(he)金屬(shu)鋁(lv)(lv)(lv)粉(fen)(fen)在流動氨氣效果下，原位生成Al?O?-TiN復相(xiang)資料等。

所謂(wei)組(zu)成(cheng)耐火(huo)質(zhi)料(liao)，就是(shi)將兩種或(huo)兩種以上的(de)天然礦藏質(zhi)料(liao)或(huo)化工質(zhi)料(liao)或(huo)廢(fei)棄物，通過(guo)配料(liao)、粉碎(sui)，磨細，混合，成(cheng)型，煅燒或(huo)電熔等工藝進程(cheng)，合成(cheng)鎂鐵(tie)鈣砂(sha)制取(qu)必定(ding)化學礦藏組(zu)成(cheng)和(he)物理性能的(de)耐火(huo)質(zhi)料(liao)。
