所(suo)謂組成耐(nai)(nai)火質(zhi)料，就是將兩種或兩種以上的天(tian)然礦藏(zang)(zang)質(zhi)料或化工質(zhi)料或廢棄物(wu)，通過配料、粉碎，磨細，混合，成型，煅燒(shao)或電熔等工藝進程，合成鎂鐵鈣砂制取(qu)必定化學(xue)礦藏(zang)(zang)組成和物(wu)理性能的耐(nai)(nai)火質(zhi)料。組成耐(nai)(nai)火質(zhi)料的品種繁(fan)復，組成辦法多種多樣(yang)，大體簡略介紹(shao)：

 純化(hua)(hua)工質(zhi)料之間組(zu)(zu)成(cheng)耐火質(zhi)料，如用(yong)工業(ye)氧化(hua)(hua)鋁(lv)(lv)與鈦白(bai)粉(fen)組(zu)(zu)成(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)與氮(dan)氣(qi)化(hua)(hua)合組(zu)(zu)成(cheng)AIN(氮(dan)化(hua)(hua)鋁(lv)(lv));工業(ye)氧化(hua)(hua)鋁(lv)(lv)與高純超(chao)細的氮(dan)化(hua)(hua)鋁(lv)(lv)粉(fen)組(zu)(zu)成(cheng)Alon(阿隆(long));用(yong)輕質(zhi)碳酸鈣與工業(ye)氧化(hua)(hua)鋁(lv)(lv)，按CA6的CaO與Al?O?的化(hua)(hua)學計量比(bi)例配(pei)料，組(zu)(zu)成(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白(bai)粉(fen)和金屬鋁(lv)(lv)粉(fen)在流動(dong)氨氣(qi)效果下，原位(wei)生成(cheng)Al?O?-TiN復相資料等(deng)。

所(suo)謂(wei)組成(cheng)耐(nai)火(huo)質料(liao)(liao)，就是(shi)將兩種(zhong)或(huo)(huo)(huo)兩種(zhong)以上的天(tian)然(ran)礦(kuang)(kuang)藏質料(liao)(liao)或(huo)(huo)(huo)化(hua)工質料(liao)(liao)或(huo)(huo)(huo)廢棄物(wu)，通過配(pei)料(liao)(liao)、粉碎，磨細(xi)，混合，成(cheng)型，煅燒或(huo)(huo)(huo)電熔等(deng)工藝進程(cheng)，合成(cheng)鎂鐵(tie)鈣砂制取(qu)必定化(hua)學礦(kuang)(kuang)藏組成(cheng)和物(wu)理性(xing)能(neng)的耐(nai)火(huo)質料(liao)(liao)。
