所謂組成耐(nai)(nai)火質(zhi)(zhi)料，就是(shi)將兩種(zhong)或(huo)(huo)兩種(zhong)以上的天然(ran)礦(kuang)藏質(zhi)(zhi)料或(huo)(huo)化工質(zhi)(zhi)料或(huo)(huo)廢棄物，通過配料、粉碎，磨細，混(hun)合，成型(xing)，煅(duan)燒或(huo)(huo)電熔等工藝(yi)進程，合成鎂鐵鈣砂制取必定化學礦(kuang)藏組成和物理性能的耐(nai)(nai)火質(zhi)(zhi)料。組成耐(nai)(nai)火質(zhi)(zhi)料的品種(zhong)繁復(fu)，組成辦法多種(zhong)多樣，大體簡略介(jie)紹(shao)：

 純(chun)化(hua)(hua)(hua)工(gong)(gong)質(zhi)(zhi)料之間組(zu)成耐(nai)火(huo)質(zhi)(zhi)料，如用工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)與鈦(tai)白粉(fen)組(zu)成鈦(tai)酸(suan)鋁(lv);鋁(lv)粉(fen)與氮氣化(hua)(hua)(hua)合組(zu)成AIN(氮化(hua)(hua)(hua)鋁(lv));工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)與高純(chun)超細的氮化(hua)(hua)(hua)鋁(lv)粉(fen)組(zu)成Alon(阿(a)隆(long));用輕質(zhi)(zhi)碳酸(suan)鈣與工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)，按CA6的CaO與Al?O?的化(hua)(hua)(hua)學計量比例配(pei)料，組(zu)成六鋁(lv)酸(suan)鈣;用鈦(tai)白粉(fen)和金(jin)屬鋁(lv)粉(fen)在流動氨氣效果下，原位(wei)生(sheng)成Al?O?-TiN復(fu)相資料等。

所謂組成(cheng)耐火質料(liao)，就是將兩種或(huo)兩種以上(shang)的天(tian)然礦藏質料(liao)或(huo)化工質料(liao)或(huo)廢(fei)棄物，通過配料(liao)、粉碎(sui)，磨細，混合，成(cheng)型，煅(duan)燒或(huo)電(dian)熔等工藝(yi)進程(cheng)，合成(cheng)鎂(mei)鐵鈣砂制取必定化學礦藏組成(cheng)和物理性能的耐火質料(liao)。
