所謂組(zu)成耐火質(zhi)料(liao)，就(jiu)是(shi)將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以上的(de)天然礦(kuang)藏質(zhi)料(liao)或(huo)化工質(zhi)料(liao)或(huo)廢棄(qi)物(wu)，通過配料(liao)、粉碎(sui)，磨細(xi)，混(hun)合，成型，煅燒或(huo)電(dian)熔等工藝進程，合成鎂鐵鈣砂制取(qu)必定化學礦(kuang)藏組(zu)成和(he)物(wu)理性能(neng)的(de)耐火質(zhi)料(liao)。組(zu)成耐火質(zhi)料(liao)的(de)品種(zhong)繁復，組(zu)成辦法多種(zhong)多樣(yang)，大體簡略介紹：

 純化(hua)(hua)(hua)工(gong)(gong)質料之間組(zu)成(cheng)(cheng)耐火質料，如用工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)(lv)與(yu)鈦(tai)白(bai)粉(fen)組(zu)成(cheng)(cheng)鈦(tai)酸鋁(lv)(lv)(lv);鋁(lv)(lv)(lv)粉(fen)與(yu)氮(dan)(dan)氣(qi)化(hua)(hua)(hua)合組(zu)成(cheng)(cheng)AIN(氮(dan)(dan)化(hua)(hua)(hua)鋁(lv)(lv)(lv));工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)(lv)與(yu)高純超細的氮(dan)(dan)化(hua)(hua)(hua)鋁(lv)(lv)(lv)粉(fen)組(zu)成(cheng)(cheng)Alon(阿(a)隆);用輕質碳酸鈣與(yu)工(gong)(gong)業(ye)氧(yang)化(hua)(hua)(hua)鋁(lv)(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)(hua)學計量比例配(pei)料，組(zu)成(cheng)(cheng)六鋁(lv)(lv)(lv)酸鈣;用鈦(tai)白(bai)粉(fen)和金屬鋁(lv)(lv)(lv)粉(fen)在(zai)流動氨氣(qi)效果下，原位生成(cheng)(cheng)Al?O?-TiN復相(xiang)資(zi)料等。

所謂組成(cheng)耐火質料(liao)(liao)，就是將(jiang)兩種(zhong)或(huo)(huo)兩種(zhong)以上的天然(ran)礦藏(zang)質料(liao)(liao)或(huo)(huo)化工質料(liao)(liao)或(huo)(huo)廢棄(qi)物，通過配(pei)料(liao)(liao)、粉碎，磨細，混合(he)，成(cheng)型(xing)，煅燒或(huo)(huo)電(dian)熔等工藝進程，合(he)成(cheng)鎂鐵鈣砂制取必定化學礦藏(zang)組成(cheng)和物理性能的耐火質料(liao)(liao)。
