所謂組(zu)(zu)成(cheng)(cheng)耐火(huo)質(zhi)料(liao)，就是將(jiang)兩(liang)種(zhong)(zhong)或(huo)兩(liang)種(zhong)(zhong)以(yi)上(shang)的天(tian)然礦(kuang)藏(zang)質(zhi)料(liao)或(huo)化(hua)(hua)工質(zhi)料(liao)或(huo)廢(fei)棄物(wu)，通過配料(liao)、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅(duan)燒或(huo)電熔等工藝(yi)進程，合(he)成(cheng)(cheng)鎂鐵鈣砂制(zhi)取必定(ding)化(hua)(hua)學礦(kuang)藏(zang)組(zu)(zu)成(cheng)(cheng)和物(wu)理性能的耐火(huo)質(zhi)料(liao)。組(zu)(zu)成(cheng)(cheng)耐火(huo)質(zhi)料(liao)的品(pin)種(zhong)(zhong)繁復，組(zu)(zu)成(cheng)(cheng)辦法(fa)多(duo)種(zhong)(zhong)多(duo)樣(yang)，大體簡略介(jie)紹：

 純化(hua)(hua)工(gong)質料(liao)(liao)之間(jian)組成耐火質料(liao)(liao)，如用工(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)(yu)鈦白粉(fen)組成鈦酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)與(yu)(yu)氮氣(qi)化(hua)(hua)合(he)組成AIN(氮化(hua)(hua)鋁(lv)(lv));工(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)(yu)高純超細的氮化(hua)(hua)鋁(lv)(lv)粉(fen)組成Alon(阿隆);用輕質碳酸鈣與(yu)(yu)工(gong)業氧化(hua)(hua)鋁(lv)(lv)，按CA6的CaO與(yu)(yu)Al?O?的化(hua)(hua)學計量比例(li)配(pei)料(liao)(liao)，組成六鋁(lv)(lv)酸鈣;用鈦白粉(fen)和金屬鋁(lv)(lv)粉(fen)在流動氨氣(qi)效果下(xia)，原(yuan)位(wei)生成Al?O?-TiN復相資料(liao)(liao)等(deng)。

所(suo)謂組成耐火(huo)(huo)質(zhi)(zhi)料(liao)，就是將兩種或兩種以上的天然礦藏質(zhi)(zhi)料(liao)或化工質(zhi)(zhi)料(liao)或廢棄(qi)物，通過(guo)配料(liao)、粉碎，磨細，混合，成型(xing)，煅燒或電熔等工藝進程，合成鎂鐵(tie)鈣砂制取(qu)必定化學礦藏組成和(he)物理(li)性(xing)能(neng)的耐火(huo)(huo)質(zhi)(zhi)料(liao)。
