所謂組成耐(nai)火質(zhi)(zhi)料(liao)，就是(shi)將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以上的天然礦藏質(zhi)(zhi)料(liao)或(huo)化(hua)工質(zhi)(zhi)料(liao)或(huo)廢棄物(wu)(wu)，通過配料(liao)、粉碎，磨(mo)細，混合，成型，煅(duan)燒或(huo)電(dian)熔(rong)等工藝(yi)進程，合成鎂鐵鈣砂制取(qu)必定化(hua)學礦藏組成和物(wu)(wu)理性能的耐(nai)火質(zhi)(zhi)料(liao)。組成耐(nai)火質(zhi)(zhi)料(liao)的品種(zhong)繁復，組成辦法多(duo)種(zhong)多(duo)樣，大體簡略介紹(shao)：

 純化(hua)工(gong)質料(liao)之間組成(cheng)(cheng)耐火質料(liao)，如(ru)用(yong)工(gong)業氧(yang)化(hua)鋁(lv)(lv)與鈦白(bai)粉(fen)(fen)組成(cheng)(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)(fen)與氮(dan)(dan)氣化(hua)合組成(cheng)(cheng)AIN(氮(dan)(dan)化(hua)鋁(lv)(lv));工(gong)業氧(yang)化(hua)鋁(lv)(lv)與高純超(chao)細的氮(dan)(dan)化(hua)鋁(lv)(lv)粉(fen)(fen)組成(cheng)(cheng)Alon(阿(a)隆);用(yong)輕質碳酸鈣與工(gong)業氧(yang)化(hua)鋁(lv)(lv)，按CA6的CaO與Al?O?的化(hua)學計量比(bi)例(li)配料(liao)，組成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白(bai)粉(fen)(fen)和金(jin)屬鋁(lv)(lv)粉(fen)(fen)在流(liu)動氨氣效果下(xia)，原位生成(cheng)(cheng)Al?O?-TiN復相資料(liao)等(deng)。

所謂(wei)組(zu)成耐(nai)火質(zhi)料，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以(yi)上的(de)天(tian)然礦藏質(zhi)料或(huo)(huo)化(hua)工質(zhi)料或(huo)(huo)廢(fei)棄物(wu)(wu)，通過配料、粉碎，磨細，混合，成型，煅燒或(huo)(huo)電熔等工藝(yi)進程，合成鎂鐵鈣砂制取必定化(hua)學(xue)礦藏組(zu)成和物(wu)(wu)理性(xing)能的(de)耐(nai)火質(zhi)料。
