所謂(wei)組成耐火質料，就(jiu)是(shi)將兩(liang)(liang)種(zhong)或(huo)兩(liang)(liang)種(zhong)以上的天(tian)然礦藏(zang)質料或(huo)化工質料或(huo)廢棄物，通過配料、粉(fen)碎，磨細，混合(he)，成型，煅燒或(huo)電熔等(deng)工藝(yi)進(jin)程，合(he)成鎂鐵鈣砂(sha)制取必(bi)定化學礦藏(zang)組成和物理性能的耐火質料。組成耐火質料的品種(zhong)繁復，組成辦法多種(zhong)多樣，大(da)體簡略(lve)介紹：

 純化工(gong)質料之(zhi)間組(zu)成(cheng)(cheng)耐(nai)火質料，如用(yong)工(gong)業(ye)氧(yang)化鋁(lv)(lv)(lv)(lv)與鈦(tai)白粉(fen)(fen)(fen)組(zu)成(cheng)(cheng)鈦(tai)酸鋁(lv)(lv)(lv)(lv);鋁(lv)(lv)(lv)(lv)粉(fen)(fen)(fen)與氮氣(qi)(qi)化合組(zu)成(cheng)(cheng)AIN(氮化鋁(lv)(lv)(lv)(lv));工(gong)業(ye)氧(yang)化鋁(lv)(lv)(lv)(lv)與高純超(chao)細的氮化鋁(lv)(lv)(lv)(lv)粉(fen)(fen)(fen)組(zu)成(cheng)(cheng)Alon(阿隆);用(yong)輕質碳(tan)酸鈣與工(gong)業(ye)氧(yang)化鋁(lv)(lv)(lv)(lv)，按CA6的CaO與Al?O?的化學計量比例配料，組(zu)成(cheng)(cheng)六鋁(lv)(lv)(lv)(lv)酸鈣;用(yong)鈦(tai)白粉(fen)(fen)(fen)和金屬(shu)鋁(lv)(lv)(lv)(lv)粉(fen)(fen)(fen)在流動氨氣(qi)(qi)效果(guo)下，原位生(sheng)成(cheng)(cheng)Al?O?-TiN復相資料等。

所謂組(zu)成耐火質(zhi)(zhi)(zhi)料(liao)，就是將兩種或兩種以(yi)上的天然礦藏質(zhi)(zhi)(zhi)料(liao)或化(hua)工質(zhi)(zhi)(zhi)料(liao)或廢棄物，通過配(pei)料(liao)、粉碎，磨細，混合，成型，煅燒或電熔等工藝進程，合成鎂鐵(tie)鈣砂制取必(bi)定化(hua)學礦藏組(zu)成和物理(li)性能的耐火質(zhi)(zhi)(zhi)料(liao)。
