所謂組(zu)成(cheng)(cheng)(cheng)(cheng)耐火質(zhi)料，就是將兩種或兩種以上的(de)天然礦藏質(zhi)料或化(hua)工質(zhi)料或廢棄物，通(tong)過配料、粉碎，磨細，混合，成(cheng)(cheng)(cheng)(cheng)型，煅燒或電熔等工藝(yi)進程，合成(cheng)(cheng)(cheng)(cheng)鎂(mei)鐵鈣砂制取(qu)必定化(hua)學礦藏組(zu)成(cheng)(cheng)(cheng)(cheng)和物理性能的(de)耐火質(zhi)料。組(zu)成(cheng)(cheng)(cheng)(cheng)耐火質(zhi)料的(de)品種繁復，組(zu)成(cheng)(cheng)(cheng)(cheng)辦法多種多樣(yang)，大體簡略介紹：

 純化(hua)工(gong)質(zhi)料(liao)(liao)之間組(zu)(zu)(zu)成(cheng)耐火質(zhi)料(liao)(liao)，如(ru)用(yong)工(gong)業(ye)氧(yang)化(hua)鋁(lv)與鈦白(bai)粉(fen)(fen)組(zu)(zu)(zu)成(cheng)鈦酸(suan)鋁(lv);鋁(lv)粉(fen)(fen)與氮氣(qi)化(hua)合(he)組(zu)(zu)(zu)成(cheng)AIN(氮化(hua)鋁(lv));工(gong)業(ye)氧(yang)化(hua)鋁(lv)與高純超細的氮化(hua)鋁(lv)粉(fen)(fen)組(zu)(zu)(zu)成(cheng)Alon(阿隆);用(yong)輕(qing)質(zhi)碳酸(suan)鈣(gai)與工(gong)業(ye)氧(yang)化(hua)鋁(lv)，按CA6的CaO與Al?O?的化(hua)學(xue)計量比例(li)配料(liao)(liao)，組(zu)(zu)(zu)成(cheng)六鋁(lv)酸(suan)鈣(gai);用(yong)鈦白(bai)粉(fen)(fen)和金屬鋁(lv)粉(fen)(fen)在流動氨(an)氣(qi)效果下(xia)，原位生(sheng)成(cheng)Al?O?-TiN復(fu)相資料(liao)(liao)等(deng)。

所(suo)謂(wei)組成耐火(huo)質(zhi)料，就是將兩種或兩種以上(shang)的(de)天然(ran)礦(kuang)藏質(zhi)料或化工質(zhi)料或廢棄(qi)物，通過配料、粉碎，磨細，混合，成型，煅燒或電熔等工藝進(jin)程(cheng)，合成鎂鐵(tie)鈣砂制取必定化學礦(kuang)藏組成和物理性能的(de)耐火(huo)質(zhi)料。
