 可用天然礦(kuang)藏質料本身之間的檔(dang)次不同配(pei)(pei)料組(zu)成(cheng)(cheng)(cheng)(cheng)，如莫(mo)來(lai)石(shi)(shi)，也可不同天然礦(kuang)藏質料配(pei)(pei)料組(zu)成(cheng)(cheng)(cheng)(cheng)，如用高(gao)(gao)鋁(lv)礬(fan)土與鋯英石(shi)(shi)精(jing)礦(kuang)組(zu)成(cheng)(cheng)(cheng)(cheng)鋯莫(mo)來(lai)石(shi)(shi);高(gao)(gao)鋁(lv)礬(fan)土與菱(ling)鎂礦(kuang)組(zu)成(cheng)(cheng)(cheng)(cheng)鋁(lv)鎂尖(jian)(jian)晶石(shi)(shi);菱(ling)鎂礦(kuang)與白云石(shi)(shi)組(zu)成(cheng)(cheng)(cheng)(cheng)鎂鈣砂(sha)(sha);用高(gao)(gao)鈣菱(ling)鎂礦(kuang)與鐵(tie)(tie)精(jing)礦(kuang)配(pei)(pei)料組(zu)成(cheng)(cheng)(cheng)(cheng)鎂鐵(tie)(tie)鈣砂(sha)(sha);菱(ling)鎂礦(kuang)與鋯英石(shi)(shi)組(zu)成(cheng)(cheng)(cheng)(cheng)鎂鋯砂(sha)(sha);葉(xie)蠟石(shi)(shi)與滑石(shi)(shi)組(zu)成(cheng)(cheng)(cheng)(cheng)堇(jin)青石(shi)(shi);用菱(ling)鎂礦(kuang)與二(er)級(ji)高(gao)(gao)鋁(lv)礬(fan)土熟料配(pei)(pei)料，焦炭作為還原(yuan)劑，通過碳(tan)熱還原(yuan)氮化(hua)組(zu)成(cheng)(cheng)(cheng)(cheng)Sialon—尖(jian)(jian)晶石(shi)(shi)復(fu)相(xiang)資(zi)料;藍晶石(shi)(shi)與石(shi)(shi)墨配(pei)(pei)料，原(yuan)位組(zu)成(cheng)(cheng)(cheng)(cheng)AlN—SiC復(fu)相(xiang)資(zi)料等。

所謂組(zu)(zu)成(cheng)耐火質料(liao)，就是將兩(liang)種或兩(liang)種以上(shang)的天然礦(kuang)(kuang)藏質料(liao)或化工(gong)質料(liao)或廢棄物，通(tong)過配(pei)料(liao)、粉碎(sui)，磨細(xi)，混合(he)，成(cheng)型，煅燒或電(dian)熔等工(gong)藝進程，合(he)成(cheng)鎂鐵鈣砂制取必定化學(xue)礦(kuang)(kuang)藏組(zu)(zu)成(cheng)和(he)物理性能的耐火質料(liao)。組(zu)(zu)成(cheng)耐火質料(liao)的品種繁(fan)復，組(zu)(zu)成(cheng)辦法多種多樣，大體簡略介紹：

 純化(hua)(hua)工質料之間組成(cheng)耐火質料，如用工業(ye)(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)與(yu)(yu)(yu)(yu)鈦白粉(fen)組成(cheng)鈦酸(suan)鋁(lv)(lv)(lv);鋁(lv)(lv)(lv)粉(fen)與(yu)(yu)(yu)(yu)氮氣(qi)化(hua)(hua)合組成(cheng)AIN(氮化(hua)(hua)鋁(lv)(lv)(lv));工業(ye)(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)與(yu)(yu)(yu)(yu)高純超細的(de)氮化(hua)(hua)鋁(lv)(lv)(lv)粉(fen)組成(cheng)Alon(阿隆);用輕質碳酸(suan)鈣(gai)與(yu)(yu)(yu)(yu)工業(ye)(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)(lv)，按CA6的(de)CaO與(yu)(yu)(yu)(yu)Al?O?的(de)化(hua)(hua)學計量(liang)比例配(pei)料，組成(cheng)六鋁(lv)(lv)(lv)酸(suan)鈣(gai);用鈦白粉(fen)和金屬(shu)鋁(lv)(lv)(lv)粉(fen)在流動氨(an)氣(qi)效果下，原位生成(cheng)Al?O?-TiN復相資料等(deng)。

所謂(wei)組(zu)成(cheng)(cheng)(cheng)耐火質(zhi)(zhi)(zhi)料(liao)，就是將兩種或兩種以上的天然礦藏(zang)質(zhi)(zhi)(zhi)料(liao)或化工質(zhi)(zhi)(zhi)料(liao)或廢棄物(wu)，通過配料(liao)、粉碎，磨(mo)細，混(hun)合，成(cheng)(cheng)(cheng)型，煅(duan)燒或電熔等工藝進程，合成(cheng)(cheng)(cheng)鎂鐵(tie)鈣砂制取必定(ding)化學礦藏(zang)組(zu)成(cheng)(cheng)(cheng)和(he)物(wu)理(li)性能的耐火質(zhi)(zhi)(zhi)料(liao)。
