所謂(wei)組(zu)成耐火質料，就是將兩種或(huo)(huo)兩種以(yi)上的(de)天然(ran)礦(kuang)藏質料或(huo)(huo)化工質料或(huo)(huo)廢(fei)棄(qi)物(wu)，通(tong)過配料、粉碎，磨細(xi)，混合，成型，煅燒或(huo)(huo)電熔等工藝進程，合成鎂(mei)鐵鈣砂制(zhi)取必定化學(xue)礦(kuang)藏組(zu)成和物(wu)理性(xing)能(neng)的(de)耐火質料。組(zu)成耐火質料的(de)品(pin)種繁復，組(zu)成辦法多種多樣，大體簡略介紹(shao)：

 純(chun)化工(gong)質料(liao)(liao)(liao)之間組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)耐火質料(liao)(liao)(liao)，如用(yong)(yong)工(gong)業(ye)氧(yang)化鋁(lv)與鈦白粉(fen)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)鈦酸鋁(lv);鋁(lv)粉(fen)與氮氣化合(he)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)AIN(氮化鋁(lv));工(gong)業(ye)氧(yang)化鋁(lv)與高純(chun)超(chao)細的氮化鋁(lv)粉(fen)組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)Alon(阿隆);用(yong)(yong)輕(qing)質碳酸鈣與工(gong)業(ye)氧(yang)化鋁(lv)，按CA6的CaO與Al?O?的化學(xue)計量比例配料(liao)(liao)(liao)，組(zu)(zu)成(cheng)(cheng)(cheng)(cheng)六鋁(lv)酸鈣;用(yong)(yong)鈦白粉(fen)和金屬鋁(lv)粉(fen)在流動氨氣效果下(xia)，原位生(sheng)成(cheng)(cheng)(cheng)(cheng)Al?O?-TiN復(fu)相資料(liao)(liao)(liao)等。

所謂組成(cheng)耐火(huo)質料(liao)，就(jiu)是將兩種或兩種以上的天(tian)然礦藏(zang)質料(liao)或化(hua)工質料(liao)或廢(fei)棄物(wu)，通(tong)過配料(liao)、粉碎，磨細(xi)，混合，成(cheng)型，煅(duan)燒或電熔等(deng)工藝進程，合成(cheng)鎂鐵鈣(gai)砂制取(qu)必定化(hua)學礦藏(zang)組成(cheng)和物(wu)理(li)性能的耐火(huo)質料(liao)。
