所謂組成(cheng)耐(nai)火(huo)質(zhi)料(liao)(liao)，就是將兩種(zhong)(zhong)(zhong)或兩種(zhong)(zhong)(zhong)以(yi)上的(de)天(tian)然礦藏質(zhi)料(liao)(liao)或化(hua)(hua)工質(zhi)料(liao)(liao)或廢棄物(wu)，通過配料(liao)(liao)、粉(fen)碎，磨(mo)細(xi)，混合，成(cheng)型(xing)，煅燒(shao)或電(dian)熔等工藝進程，合成(cheng)鎂鐵鈣砂制(zhi)取必定化(hua)(hua)學(xue)礦藏組成(cheng)和物(wu)理性能(neng)的(de)耐(nai)火(huo)質(zhi)料(liao)(liao)。組成(cheng)耐(nai)火(huo)質(zhi)料(liao)(liao)的(de)品(pin)種(zhong)(zhong)(zhong)繁復，組成(cheng)辦法(fa)多種(zhong)(zhong)(zhong)多樣，大體(ti)簡略介紹：

 純(chun)化工(gong)質料(liao)之間組(zu)成(cheng)耐火質料(liao)，如用(yong)工(gong)業(ye)氧化鋁(lv)與鈦(tai)(tai)白粉(fen)組(zu)成(cheng)鈦(tai)(tai)酸鋁(lv);鋁(lv)粉(fen)與氮(dan)氣化合(he)組(zu)成(cheng)AIN(氮(dan)化鋁(lv));工(gong)業(ye)氧化鋁(lv)與高純(chun)超(chao)細的氮(dan)化鋁(lv)粉(fen)組(zu)成(cheng)Alon(阿隆);用(yong)輕(qing)質碳酸鈣(gai)與工(gong)業(ye)氧化鋁(lv)，按(an)CA6的CaO與Al?O?的化學計量(liang)比例配料(liao)，組(zu)成(cheng)六鋁(lv)酸鈣(gai);用(yong)鈦(tai)(tai)白粉(fen)和(he)金(jin)屬鋁(lv)粉(fen)在(zai)流動氨氣效果下，原位生成(cheng)Al?O?-TiN復相(xiang)資料(liao)等。

所謂組成(cheng)耐火質(zhi)料(liao)(liao)，就(jiu)是(shi)將兩種或(huo)兩種以上的天然礦藏質(zhi)料(liao)(liao)或(huo)化(hua)(hua)工質(zhi)料(liao)(liao)或(huo)廢棄物，通過(guo)配料(liao)(liao)、粉碎(sui)，磨細，混合，成(cheng)型(xing)，煅燒(shao)或(huo)電(dian)熔等工藝進(jin)程(cheng)，合成(cheng)鎂鐵(tie)鈣(gai)砂制(zhi)取必定化(hua)(hua)學(xue)礦藏組成(cheng)和物理性(xing)能的耐火質(zhi)料(liao)(liao)。
