所謂(wei)組(zu)成(cheng)耐火(huo)質料，就是將兩種或兩種以上的天然礦藏質料或化工質料或廢棄物，通過配料、粉碎，磨細，混合，成(cheng)型(xing)，煅燒或電熔等工藝進程，合成(cheng)鎂(mei)鐵(tie)鈣砂制取必(bi)定化學礦藏組(zu)成(cheng)和(he)物理性能的耐火(huo)質料。組(zu)成(cheng)耐火(huo)質料的品(pin)種繁(fan)復，組(zu)成(cheng)辦法多種多樣，大(da)體簡略介(jie)紹：

 純化工(gong)質(zhi)料之間組(zu)成(cheng)耐火質(zhi)料，如用(yong)工(gong)業氧(yang)化鋁(lv)與(yu)鈦(tai)白粉組(zu)成(cheng)鈦(tai)酸(suan)(suan)鋁(lv);鋁(lv)粉與(yu)氮氣化合組(zu)成(cheng)AIN(氮化鋁(lv));工(gong)業氧(yang)化鋁(lv)與(yu)高純超細(xi)的氮化鋁(lv)粉組(zu)成(cheng)Alon(阿(a)隆);用(yong)輕質(zhi)碳酸(suan)(suan)鈣與(yu)工(gong)業氧(yang)化鋁(lv)，按CA6的CaO與(yu)Al?O?的化學計量比例配料，組(zu)成(cheng)六鋁(lv)酸(suan)(suan)鈣;用(yong)鈦(tai)白粉和金屬鋁(lv)粉在流動(dong)氨(an)氣效(xiao)果下，原位生成(cheng)Al?O?-TiN復(fu)相資料等。

所謂組成耐火質(zhi)(zhi)(zhi)料(liao)，就是將兩種(zhong)或兩種(zhong)以上的(de)(de)天然礦(kuang)藏質(zhi)(zhi)(zhi)料(liao)或化工質(zhi)(zhi)(zhi)料(liao)或廢棄物(wu)，通過配(pei)料(liao)、粉碎，磨(mo)細，混合(he)，成型，煅燒或電熔(rong)等(deng)工藝(yi)進程，合(he)成鎂鐵鈣砂制取必定化學礦(kuang)藏組成和物(wu)理性能的(de)(de)耐火質(zhi)(zhi)(zhi)料(liao)。
