所謂組成(cheng)耐(nai)火(huo)質料，就是將兩種(zhong)或(huo)兩種(zhong)以上的天然(ran)礦藏(zang)質料或(huo)化工(gong)質料或(huo)廢棄(qi)物(wu)，通過配料、粉碎，磨(mo)細(xi)，混合，成(cheng)型，煅燒或(huo)電(dian)熔等(deng)工(gong)藝進程，合成(cheng)鎂鐵鈣砂制(zhi)取(qu)必定化學礦藏(zang)組成(cheng)和物(wu)理(li)性(xing)能的耐(nai)火(huo)質料。組成(cheng)耐(nai)火(huo)質料的品種(zhong)繁復，組成(cheng)辦法(fa)多(duo)種(zhong)多(duo)樣，大(da)體簡略介紹：

 純化(hua)(hua)工(gong)質(zhi)料之間組(zu)成(cheng)(cheng)耐火質(zhi)料，如用工(gong)業氧化(hua)(hua)鋁(lv)與(yu)(yu)鈦白粉(fen)組(zu)成(cheng)(cheng)鈦酸鋁(lv);鋁(lv)粉(fen)與(yu)(yu)氮(dan)氣(qi)化(hua)(hua)合組(zu)成(cheng)(cheng)AIN(氮(dan)化(hua)(hua)鋁(lv));工(gong)業氧化(hua)(hua)鋁(lv)與(yu)(yu)高純超細的(de)氮(dan)化(hua)(hua)鋁(lv)粉(fen)組(zu)成(cheng)(cheng)Alon(阿(a)隆);用輕質(zhi)碳酸鈣與(yu)(yu)工(gong)業氧化(hua)(hua)鋁(lv)，按CA6的(de)CaO與(yu)(yu)Al?O?的(de)化(hua)(hua)學計量比例配料，組(zu)成(cheng)(cheng)六鋁(lv)酸鈣;用鈦白粉(fen)和金(jin)屬(shu)鋁(lv)粉(fen)在流動氨(an)氣(qi)效(xiao)果下，原(yuan)位生成(cheng)(cheng)Al?O?-TiN復相(xiang)資料等。

所謂(wei)組(zu)(zu)成耐火質料(liao)(liao)，就是(shi)將兩種或(huo)(huo)兩種以上的(de)天(tian)然(ran)礦藏質料(liao)(liao)或(huo)(huo)化(hua)工質料(liao)(liao)或(huo)(huo)廢棄(qi)物(wu)(wu)，通過配(pei)料(liao)(liao)、粉碎，磨(mo)細，混合，成型(xing)，煅燒或(huo)(huo)電熔等工藝進(jin)程，合成鎂鐵(tie)鈣砂制取必定化(hua)學(xue)礦藏組(zu)(zu)成和(he)物(wu)(wu)理性能的(de)耐火質料(liao)(liao)。
