 可用(yong)天然礦藏質料(liao)(liao)本身(shen)之間的檔次不同配料(liao)(liao)組成(cheng)(cheng)(cheng)，如莫來石(shi)，也可不同天然礦藏質料(liao)(liao)配料(liao)(liao)組成(cheng)(cheng)(cheng)，如用(yong)高(gao)(gao)鋁(lv)礬土與(yu)鋯(gao)(gao)(gao)(gao)英(ying)石(shi)精(jing)礦組成(cheng)(cheng)(cheng)鋯(gao)(gao)(gao)(gao)莫來石(shi);高(gao)(gao)鋁(lv)礬土與(yu)菱鎂礦組成(cheng)(cheng)(cheng)鋁(lv)鎂尖(jian)晶石(shi);菱鎂礦與(yu)白(bai)云(yun)石(shi)組成(cheng)(cheng)(cheng)鎂鈣砂(sha);用(yong)高(gao)(gao)鈣菱鎂礦與(yu)鐵(tie)精(jing)礦配料(liao)(liao)組成(cheng)(cheng)(cheng)鎂鐵(tie)鈣砂(sha);菱鎂礦與(yu)鋯(gao)(gao)(gao)(gao)英(ying)石(shi)組成(cheng)(cheng)(cheng)鎂鋯(gao)(gao)(gao)(gao)砂(sha);葉蠟(la)石(shi)與(yu)滑石(shi)組成(cheng)(cheng)(cheng)堇(jin)青(qing)石(shi);用(yong)菱鎂礦與(yu)二級高(gao)(gao)鋁(lv)礬土熟料(liao)(liao)配料(liao)(liao)，焦炭作(zuo)為還原劑，通過碳熱(re)還原氮化組成(cheng)(cheng)(cheng)Sialon—尖(jian)晶石(shi)復相(xiang)資料(liao)(liao);藍晶石(shi)與(yu)石(shi)墨配料(liao)(liao)，原位組成(cheng)(cheng)(cheng)AlN—SiC復相(xiang)資料(liao)(liao)等。

所謂組成(cheng)耐火(huo)質料(liao)，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以上的(de)天然礦藏(zang)質料(liao)或(huo)(huo)化(hua)(hua)工質料(liao)或(huo)(huo)廢(fei)棄(qi)物，通過(guo)配(pei)料(liao)、粉(fen)碎，磨(mo)細，混合(he)，成(cheng)型，煅燒(shao)或(huo)(huo)電熔等工藝進程，合(he)成(cheng)鎂鐵(tie)鈣砂制取必(bi)定化(hua)(hua)學礦藏(zang)組成(cheng)和物理性能的(de)耐火(huo)質料(liao)。組成(cheng)耐火(huo)質料(liao)的(de)品種(zhong)繁復，組成(cheng)辦法(fa)多種(zhong)多樣，大體簡略介紹：

 純化工(gong)質(zhi)料之間組(zu)成(cheng)(cheng)耐火質(zhi)料，如用(yong)工(gong)業(ye)(ye)氧化鋁與鈦白粉(fen)組(zu)成(cheng)(cheng)鈦酸(suan)鋁;鋁粉(fen)與氮(dan)氣化合組(zu)成(cheng)(cheng)AIN(氮(dan)化鋁);工(gong)業(ye)(ye)氧化鋁與高純超細的氮(dan)化鋁粉(fen)組(zu)成(cheng)(cheng)Alon(阿隆);用(yong)輕(qing)質(zhi)碳酸(suan)鈣與工(gong)業(ye)(ye)氧化鋁，按(an)CA6的CaO與Al?O?的化學計量比例配料，組(zu)成(cheng)(cheng)六鋁酸(suan)鈣;用(yong)鈦白粉(fen)和金屬鋁粉(fen)在流動氨氣效果下，原(yuan)位(wei)生成(cheng)(cheng)Al?O?-TiN復相資料等。

所謂(wei)組成(cheng)耐火質(zhi)料，就是將(jiang)兩(liang)種或(huo)兩(liang)種以(yi)上的(de)天(tian)然(ran)礦藏質(zhi)料或(huo)化工(gong)質(zhi)料或(huo)廢棄物，通過配料、粉碎，磨細(xi)，混合(he)，成(cheng)型，煅燒或(huo)電熔等(deng)工(gong)藝進程，合(he)成(cheng)鎂鐵鈣砂制(zhi)取(qu)必(bi)定化學礦藏組成(cheng)和物理性(xing)能(neng)的(de)耐火質(zhi)料。
