 可用天(tian)然礦藏質(zhi)料本身之間(jian)的檔次(ci)不(bu)同配料組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)，如(ru)莫(mo)來(lai)石(shi)(shi)(shi)(shi)，也可不(bu)同天(tian)然礦藏質(zhi)料配料組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)，如(ru)用高(gao)鋁礬(fan)土(tu)與鋯英(ying)石(shi)(shi)(shi)(shi)精礦組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鋯莫(mo)來(lai)石(shi)(shi)(shi)(shi);高(gao)鋁礬(fan)土(tu)與菱鎂(mei)(mei)(mei)礦組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鋁鎂(mei)(mei)(mei)尖晶石(shi)(shi)(shi)(shi);菱鎂(mei)(mei)(mei)礦與白云石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鎂(mei)(mei)(mei)鈣(gai)砂(sha);用高(gao)鈣(gai)菱鎂(mei)(mei)(mei)礦與鐵精礦配料組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鎂(mei)(mei)(mei)鐵鈣(gai)砂(sha);菱鎂(mei)(mei)(mei)礦與鋯英(ying)石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鎂(mei)(mei)(mei)鋯砂(sha);葉蠟石(shi)(shi)(shi)(shi)與滑石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)堇青石(shi)(shi)(shi)(shi);用菱鎂(mei)(mei)(mei)礦與二級高(gao)鋁礬(fan)土(tu)熟料配料，焦炭(tan)作為還原劑，通過碳(tan)熱還原氮化組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)Sialon—尖晶石(shi)(shi)(shi)(shi)復相資料;藍晶石(shi)(shi)(shi)(shi)與石(shi)(shi)(shi)(shi)墨配料，原位組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)AlN—SiC復相資料等。

所謂組成耐(nai)火質(zhi)(zhi)料(liao)(liao)，就是將兩(liang)種或兩(liang)種以上的(de)(de)天然礦藏質(zhi)(zhi)料(liao)(liao)或化工質(zhi)(zhi)料(liao)(liao)或廢棄物(wu)，通過配料(liao)(liao)、粉碎，磨細(xi)，混合，成型(xing)，煅燒或電熔等(deng)工藝進程(cheng)，合成鎂(mei)鐵鈣(gai)砂制(zhi)取必(bi)定化學(xue)礦藏組成和物(wu)理性能的(de)(de)耐(nai)火質(zhi)(zhi)料(liao)(liao)。組成耐(nai)火質(zhi)(zhi)料(liao)(liao)的(de)(de)品種繁復，組成辦法多種多樣，大體簡(jian)略介紹：

 純化(hua)(hua)工(gong)(gong)質(zhi)(zhi)料之間組(zu)成(cheng)耐火質(zhi)(zhi)料，如用工(gong)(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)鈦(tai)白粉組(zu)成(cheng)鈦(tai)酸鋁(lv)(lv);鋁(lv)(lv)粉與(yu)氮氣(qi)化(hua)(hua)合(he)組(zu)成(cheng)AIN(氮化(hua)(hua)鋁(lv)(lv));工(gong)(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)高純超細的氮化(hua)(hua)鋁(lv)(lv)粉組(zu)成(cheng)Alon(阿(a)隆);用輕質(zhi)(zhi)碳酸鈣與(yu)工(gong)(gong)業氧化(hua)(hua)鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)學(xue)計量比(bi)例配(pei)料，組(zu)成(cheng)六鋁(lv)(lv)酸鈣;用鈦(tai)白粉和金(jin)屬(shu)鋁(lv)(lv)粉在流動氨氣(qi)效果下，原(yuan)位生成(cheng)Al?O?-TiN復相(xiang)資料等。

所謂組(zu)成耐(nai)火(huo)質(zhi)料(liao)(liao)，就是(shi)將兩種或兩種以上的(de)天然礦藏質(zhi)料(liao)(liao)或化工質(zhi)料(liao)(liao)或廢(fei)棄物，通過(guo)配料(liao)(liao)、粉碎(sui)，磨細，混合，成型(xing)，煅燒或電熔(rong)等工藝進程，合成鎂鐵鈣砂制取必定化學礦藏組(zu)成和物理性(xing)能的(de)耐(nai)火(huo)質(zhi)料(liao)(liao)。
