所謂組(zu)成(cheng)(cheng)耐火(huo)(huo)質(zhi)料(liao)，就是(shi)將兩(liang)種(zhong)或兩(liang)種(zhong)以上的(de)天然礦藏質(zhi)料(liao)或化工(gong)質(zhi)料(liao)或廢棄物，通過配料(liao)、粉碎，磨細，混合(he)，成(cheng)(cheng)型(xing)，煅燒(shao)或電(dian)熔等工(gong)藝進程，合(he)成(cheng)(cheng)鎂鐵鈣砂制取必(bi)定化學礦藏組(zu)成(cheng)(cheng)和物理性(xing)能的(de)耐火(huo)(huo)質(zhi)料(liao)。組(zu)成(cheng)(cheng)耐火(huo)(huo)質(zhi)料(liao)的(de)品種(zhong)繁復，組(zu)成(cheng)(cheng)辦法多種(zhong)多樣，大體簡略介(jie)紹：

 純化工(gong)質(zhi)料(liao)之間組成耐火質(zhi)料(liao)，如(ru)用(yong)工(gong)業氧(yang)化鋁(lv)(lv)與(yu)鈦(tai)白粉(fen)組成鈦(tai)酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)與(yu)氮氣化合組成AIN(氮化鋁(lv)(lv));工(gong)業氧(yang)化鋁(lv)(lv)與(yu)高純超細的氮化鋁(lv)(lv)粉(fen)組成Alon(阿隆);用(yong)輕(qing)質(zhi)碳酸鈣(gai)與(yu)工(gong)業氧(yang)化鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化學計量比(bi)例(li)配(pei)料(liao)，組成六鋁(lv)(lv)酸鈣(gai);用(yong)鈦(tai)白粉(fen)和金屬鋁(lv)(lv)粉(fen)在流動(dong)氨氣效果下(xia)，原位生成Al?O?-TiN復相資料(liao)等。

所謂組(zu)成(cheng)(cheng)耐火質(zhi)(zhi)料，就是將兩(liang)種或(huo)(huo)兩(liang)種以上的天然礦藏(zang)質(zhi)(zhi)料或(huo)(huo)化(hua)(hua)工(gong)質(zhi)(zhi)料或(huo)(huo)廢棄物，通過(guo)配料、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅燒或(huo)(huo)電熔等工(gong)藝進(jin)程(cheng)，合(he)成(cheng)(cheng)鎂鐵鈣砂(sha)制取(qu)必(bi)定化(hua)(hua)學礦藏(zang)組(zu)成(cheng)(cheng)和(he)物理性能的耐火質(zhi)(zhi)料。
