所(suo)謂組(zu)(zu)成(cheng)耐(nai)火質(zhi)(zhi)料，就(jiu)是(shi)將兩種(zhong)或兩種(zhong)以上的天然礦藏(zang)質(zhi)(zhi)料或化工(gong)質(zhi)(zhi)料或廢棄物，通過配料、粉(fen)碎，磨細，混合(he)，成(cheng)型，煅燒或電熔等工(gong)藝進程，合(he)成(cheng)鎂鐵鈣砂制取(qu)必定化學礦藏(zang)組(zu)(zu)成(cheng)和物理性能的耐(nai)火質(zhi)(zhi)料。組(zu)(zu)成(cheng)耐(nai)火質(zhi)(zhi)料的品種(zhong)繁(fan)復，組(zu)(zu)成(cheng)辦法多種(zhong)多樣(yang)，大體(ti)簡略介紹：

 純化工(gong)(gong)質料之間組(zu)成耐火質料，如用(yong)工(gong)(gong)業(ye)(ye)氧(yang)(yang)化鋁與(yu)鈦白(bai)粉(fen)(fen)組(zu)成鈦酸(suan)鋁;鋁粉(fen)(fen)與(yu)氮氣化合組(zu)成AIN(氮化鋁);工(gong)(gong)業(ye)(ye)氧(yang)(yang)化鋁與(yu)高純超細的氮化鋁粉(fen)(fen)組(zu)成Alon(阿隆);用(yong)輕質碳酸(suan)鈣與(yu)工(gong)(gong)業(ye)(ye)氧(yang)(yang)化鋁，按CA6的CaO與(yu)Al?O?的化學計量(liang)比例配料，組(zu)成六(liu)鋁酸(suan)鈣;用(yong)鈦白(bai)粉(fen)(fen)和(he)金(jin)屬(shu)鋁粉(fen)(fen)在流動氨氣效果下，原位(wei)生成Al?O?-TiN復(fu)相資料等。

所謂組成(cheng)(cheng)耐火質料(liao)，就是(shi)將兩種或(huo)兩種以上(shang)的(de)天然礦藏(zang)質料(liao)或(huo)化工質料(liao)或(huo)廢棄物(wu)，通過(guo)配料(liao)、粉碎，磨細，混(hun)合，成(cheng)(cheng)型，煅(duan)燒或(huo)電(dian)熔(rong)等(deng)工藝進程，合成(cheng)(cheng)鎂鐵鈣砂制取必(bi)定化學礦藏(zang)組成(cheng)(cheng)和(he)物(wu)理(li)性能的(de)耐火質料(liao)。
