所謂組(zu)成耐火(huo)質料(liao)，就是(shi)將兩種(zhong)(zhong)(zhong)或(huo)兩種(zhong)(zhong)(zhong)以上的(de)天然礦藏(zang)質料(liao)或(huo)化工(gong)質料(liao)或(huo)廢(fei)棄物(wu)，通過配料(liao)、粉碎，磨細，混合，成型(xing)，煅燒或(huo)電熔等工(gong)藝進程，合成鎂鐵鈣砂制取必定化學礦藏(zang)組(zu)成和物(wu)理(li)性能的(de)耐火(huo)質料(liao)。組(zu)成耐火(huo)質料(liao)的(de)品種(zhong)(zhong)(zhong)繁復，組(zu)成辦法(fa)多(duo)種(zhong)(zhong)(zhong)多(duo)樣，大體簡略介紹：

 純化(hua)(hua)(hua)工(gong)(gong)質料之(zhi)間組(zu)(zu)成(cheng)(cheng)耐火質料，如(ru)用(yong)工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv)與(yu)(yu)鈦白粉組(zu)(zu)成(cheng)(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉與(yu)(yu)氮氣化(hua)(hua)(hua)合組(zu)(zu)成(cheng)(cheng)AIN(氮化(hua)(hua)(hua)鋁(lv)(lv));工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv)與(yu)(yu)高純超細的(de)(de)氮化(hua)(hua)(hua)鋁(lv)(lv)粉組(zu)(zu)成(cheng)(cheng)Alon(阿隆(long));用(yong)輕質碳(tan)酸鈣與(yu)(yu)工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv)，按CA6的(de)(de)CaO與(yu)(yu)Al?O?的(de)(de)化(hua)(hua)(hua)學計量(liang)比例配料，組(zu)(zu)成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白粉和金屬鋁(lv)(lv)粉在流動氨氣效果下，原位生成(cheng)(cheng)Al?O?-TiN復相資料等。

所謂組成(cheng)耐火質(zhi)料(liao)(liao)(liao)，就(jiu)是將兩種(zhong)或兩種(zhong)以上的天然(ran)礦(kuang)藏(zang)質(zhi)料(liao)(liao)(liao)或化(hua)(hua)工質(zhi)料(liao)(liao)(liao)或廢棄物，通過配料(liao)(liao)(liao)、粉碎，磨細，混(hun)合，成(cheng)型，煅燒或電熔等工藝進(jin)程，合成(cheng)鎂鐵鈣砂制取必(bi)定(ding)化(hua)(hua)學礦(kuang)藏(zang)組成(cheng)和物理性能(neng)的耐火質(zhi)料(liao)(liao)(liao)。
