所謂(wei)組成耐(nai)火質(zhi)料，就是將(jiang)兩種(zhong)(zhong)或(huo)兩種(zhong)(zhong)以(yi)上的天(tian)然(ran)礦(kuang)藏質(zhi)料或(huo)化工(gong)質(zhi)料或(huo)廢(fei)棄物，通過配料、粉碎，磨細，混(hun)合(he)，成型，煅(duan)燒或(huo)電(dian)熔等(deng)工(gong)藝進程，合(he)成鎂鐵鈣砂制取必定化學礦(kuang)藏組成和物理性(xing)能的耐(nai)火質(zhi)料。組成耐(nai)火質(zhi)料的品(pin)種(zhong)(zhong)繁復(fu)，組成辦法多種(zhong)(zhong)多樣，大體簡(jian)略介紹：

 純化(hua)工(gong)質(zhi)料(liao)之間組成(cheng)耐火質(zhi)料(liao)，如(ru)用(yong)工(gong)業(ye)氧(yang)化(hua)鋁(lv)與鈦(tai)白(bai)粉組成(cheng)鈦(tai)酸鋁(lv);鋁(lv)粉與氮(dan)氣(qi)化(hua)合組成(cheng)AIN(氮(dan)化(hua)鋁(lv));工(gong)業(ye)氧(yang)化(hua)鋁(lv)與高純超細的氮(dan)化(hua)鋁(lv)粉組成(cheng)Alon(阿(a)隆);用(yong)輕質(zhi)碳酸鈣與工(gong)業(ye)氧(yang)化(hua)鋁(lv)，按CA6的CaO與Al?O?的化(hua)學計量(liang)比例配料(liao)，組成(cheng)六鋁(lv)酸鈣;用(yong)鈦(tai)白(bai)粉和金屬(shu)鋁(lv)粉在流動氨氣(qi)效(xiao)果下，原(yuan)位生成(cheng)Al?O?-TiN復(fu)相資料(liao)等。

所謂組成(cheng)耐(nai)火質料(liao)(liao)，就是將兩種(zhong)或(huo)兩種(zhong)以上的天然礦藏質料(liao)(liao)或(huo)化(hua)工(gong)質料(liao)(liao)或(huo)廢棄物，通(tong)過配料(liao)(liao)、粉碎，磨細，混合，成(cheng)型，煅(duan)燒或(huo)電熔(rong)等工(gong)藝(yi)進程，合成(cheng)鎂鐵(tie)鈣砂制取必定(ding)化(hua)學礦藏組成(cheng)和物理性(xing)能的耐(nai)火質料(liao)(liao)。
