所(suo)謂組成耐(nai)火質(zhi)(zhi)料，就是將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以上的天然礦藏質(zhi)(zhi)料或(huo)化工(gong)質(zhi)(zhi)料或(huo)廢棄物，通過配(pei)料、粉(fen)碎，磨細(xi)，混合(he)，成型，煅燒或(huo)電熔等工(gong)藝(yi)進程，合(he)成鎂鐵鈣(gai)砂制取必定(ding)化學礦藏組成和物理性能的耐(nai)火質(zhi)(zhi)料。組成耐(nai)火質(zhi)(zhi)料的品種(zhong)繁(fan)復，組成辦法(fa)多種(zhong)多樣，大(da)體(ti)簡略介紹：

 純化(hua)工(gong)質料之間(jian)組成(cheng)耐火質料，如用(yong)工(gong)業(ye)(ye)氧(yang)化(hua)鋁(lv)(lv)與鈦白粉(fen)組成(cheng)鈦酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉(fen)與氮氣(qi)(qi)化(hua)合組成(cheng)AIN(氮化(hua)鋁(lv)(lv));工(gong)業(ye)(ye)氧(yang)化(hua)鋁(lv)(lv)與高純超細(xi)的氮化(hua)鋁(lv)(lv)粉(fen)組成(cheng)Alon(阿(a)隆(long));用(yong)輕(qing)質碳酸(suan)鈣與工(gong)業(ye)(ye)氧(yang)化(hua)鋁(lv)(lv)，按(an)CA6的CaO與Al?O?的化(hua)學(xue)計量比例配料，組成(cheng)六鋁(lv)(lv)酸(suan)鈣;用(yong)鈦白粉(fen)和金屬鋁(lv)(lv)粉(fen)在流動氨氣(qi)(qi)效果下(xia)，原位生成(cheng)Al?O?-TiN復相資料等。

所謂組(zu)成(cheng)耐火質料，就是將(jiang)兩(liang)種或兩(liang)種以上的天然礦藏(zang)質料或化工質料或廢棄物，通(tong)過(guo)配料、粉(fen)碎，磨(mo)細(xi)，混合，成(cheng)型，煅燒或電熔等(deng)工藝進程，合成(cheng)鎂鐵鈣(gai)砂制(zhi)取必定化學礦藏(zang)組(zu)成(cheng)和物理性能的耐火質料。
