所謂(wei)組(zu)成(cheng)(cheng)耐(nai)火質料(liao)，就是(shi)將(jiang)兩(liang)種(zhong)(zhong)或兩(liang)種(zhong)(zhong)以上的(de)天然(ran)礦藏質料(liao)或化(hua)(hua)工(gong)質料(liao)或廢棄物，通(tong)過配料(liao)、粉碎，磨細，混合(he)(he)，成(cheng)(cheng)型，煅燒或電熔等工(gong)藝進程(cheng)，合(he)(he)成(cheng)(cheng)鎂鐵(tie)鈣砂制(zhi)取必定化(hua)(hua)學礦藏組(zu)成(cheng)(cheng)和物理性能的(de)耐(nai)火質料(liao)。組(zu)成(cheng)(cheng)耐(nai)火質料(liao)的(de)品(pin)種(zhong)(zhong)繁(fan)復(fu)，組(zu)成(cheng)(cheng)辦(ban)法多種(zhong)(zhong)多樣，大體簡(jian)略介紹：

 純化(hua)(hua)工質料(liao)(liao)之間組成(cheng)(cheng)耐(nai)火質料(liao)(liao)，如用工業氧(yang)化(hua)(hua)鋁(lv)與鈦白粉(fen)(fen)組成(cheng)(cheng)鈦酸(suan)(suan)鋁(lv);鋁(lv)粉(fen)(fen)與氮(dan)氣化(hua)(hua)合組成(cheng)(cheng)AIN(氮(dan)化(hua)(hua)鋁(lv));工業氧(yang)化(hua)(hua)鋁(lv)與高純超細的(de)氮(dan)化(hua)(hua)鋁(lv)粉(fen)(fen)組成(cheng)(cheng)Alon(阿(a)隆);用輕質碳酸(suan)(suan)鈣與工業氧(yang)化(hua)(hua)鋁(lv)，按CA6的(de)CaO與Al?O?的(de)化(hua)(hua)學計量比(bi)例配料(liao)(liao)，組成(cheng)(cheng)六鋁(lv)酸(suan)(suan)鈣;用鈦白粉(fen)(fen)和金屬鋁(lv)粉(fen)(fen)在(zai)流動氨氣效果下，原位生成(cheng)(cheng)Al?O?-TiN復相資料(liao)(liao)等。

所謂組(zu)(zu)成耐火質料(liao)(liao)，就(jiu)是(shi)將兩(liang)種或兩(liang)種以上的天然礦藏質料(liao)(liao)或化工質料(liao)(liao)或廢棄(qi)物，通過配(pei)料(liao)(liao)、粉碎，磨細，混合，成型，煅燒或電熔(rong)等工藝進程，合成鎂鐵鈣砂制取(qu)必定(ding)化學礦藏組(zu)(zu)成和物理性能(neng)的耐火質料(liao)(liao)。
