所謂組(zu)成(cheng)(cheng)(cheng)耐(nai)火(huo)質(zhi)料(liao)(liao)，就是將(jiang)兩種(zhong)(zhong)或(huo)(huo)兩種(zhong)(zhong)以上(shang)的天然礦(kuang)藏質(zhi)料(liao)(liao)或(huo)(huo)化工(gong)質(zhi)料(liao)(liao)或(huo)(huo)廢(fei)棄物(wu)，通(tong)過(guo)配料(liao)(liao)、粉碎(sui)，磨細(xi)，混合，成(cheng)(cheng)(cheng)型，煅燒或(huo)(huo)電熔(rong)等工(gong)藝進(jin)程，合成(cheng)(cheng)(cheng)鎂(mei)鐵鈣(gai)砂制取必(bi)定(ding)化學礦(kuang)藏組(zu)成(cheng)(cheng)(cheng)和物(wu)理性能(neng)的耐(nai)火(huo)質(zhi)料(liao)(liao)。組(zu)成(cheng)(cheng)(cheng)耐(nai)火(huo)質(zhi)料(liao)(liao)的品種(zhong)(zhong)繁復(fu)，組(zu)成(cheng)(cheng)(cheng)辦法多種(zhong)(zhong)多樣，大體(ti)簡略(lve)介紹：

 純化工質料(liao)之間組成耐火質料(liao)，如用(yong)工業氧(yang)化鋁與鈦白(bai)粉(fen)(fen)組成鈦酸鋁;鋁粉(fen)(fen)與氮(dan)氣化合組成AIN(氮(dan)化鋁);工業氧(yang)化鋁與高純超細的(de)氮(dan)化鋁粉(fen)(fen)組成Alon(阿隆(long));用(yong)輕質碳酸鈣與工業氧(yang)化鋁，按CA6的(de)CaO與Al?O?的(de)化學計量(liang)比(bi)例配料(liao)，組成六鋁酸鈣;用(yong)鈦白(bai)粉(fen)(fen)和金屬鋁粉(fen)(fen)在(zai)流(liu)動(dong)氨氣效果下，原位生成Al?O?-TiN復相資料(liao)等。

所(suo)謂組成(cheng)耐火質料(liao)，就(jiu)是(shi)將兩種(zhong)(zhong)或(huo)兩種(zhong)(zhong)以上(shang)的天然(ran)礦藏質料(liao)或(huo)化(hua)工質料(liao)或(huo)廢棄物，通過配料(liao)、粉碎(sui)，磨細(xi)，混合(he)，成(cheng)型，煅燒(shao)或(huo)電熔(rong)等工藝進程，合(he)成(cheng)鎂鐵鈣砂制取必(bi)定化(hua)學礦藏組成(cheng)和(he)物理性能的耐火質料(liao)。
