所謂組(zu)(zu)成(cheng)(cheng)耐火質(zhi)料，就是將兩種或(huo)兩種以上的天然(ran)礦藏質(zhi)料或(huo)化工(gong)(gong)質(zhi)料或(huo)廢(fei)棄(qi)物(wu)，通(tong)過配料、粉(fen)碎，磨細(xi)，混(hun)合，成(cheng)(cheng)型，煅(duan)燒或(huo)電熔(rong)等(deng)工(gong)(gong)藝進程，合成(cheng)(cheng)鎂(mei)鐵(tie)鈣砂制取必(bi)定化學礦藏組(zu)(zu)成(cheng)(cheng)和物(wu)理性能的耐火質(zhi)料。組(zu)(zu)成(cheng)(cheng)耐火質(zhi)料的品種繁復，組(zu)(zu)成(cheng)(cheng)辦法多種多樣，大體簡(jian)略介(jie)紹：

 純(chun)化工(gong)質料之間組(zu)(zu)成(cheng)耐(nai)火質料，如用(yong)工(gong)業氧(yang)化鋁(lv)(lv)與鈦白粉(fen)組(zu)(zu)成(cheng)鈦酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉(fen)與氮(dan)氣化合組(zu)(zu)成(cheng)AIN(氮(dan)化鋁(lv)(lv));工(gong)業氧(yang)化鋁(lv)(lv)與高(gao)純(chun)超細的(de)氮(dan)化鋁(lv)(lv)粉(fen)組(zu)(zu)成(cheng)Alon(阿隆);用(yong)輕質碳(tan)酸(suan)鈣(gai)與工(gong)業氧(yang)化鋁(lv)(lv)，按CA6的(de)CaO與Al?O?的(de)化學(xue)計(ji)量(liang)比例配(pei)料，組(zu)(zu)成(cheng)六鋁(lv)(lv)酸(suan)鈣(gai);用(yong)鈦白粉(fen)和金(jin)屬鋁(lv)(lv)粉(fen)在流動氨氣效(xiao)果下，原位(wei)生成(cheng)Al?O?-TiN復(fu)相資料等。

所謂組成耐(nai)火質料(liao)，就是將(jiang)兩種(zhong)或(huo)(huo)(huo)(huo)兩種(zhong)以上的天(tian)然(ran)礦(kuang)藏質料(liao)或(huo)(huo)(huo)(huo)化工質料(liao)或(huo)(huo)(huo)(huo)廢棄物，通過配料(liao)、粉碎，磨細，混(hun)合，成型(xing)，煅燒(shao)或(huo)(huo)(huo)(huo)電熔等工藝進程，合成鎂鐵鈣(gai)砂制取(qu)必(bi)定化學(xue)礦(kuang)藏組成和(he)物理性能的耐(nai)火質料(liao)。
