所(suo)謂組成(cheng)(cheng)耐(nai)火(huo)質(zhi)料(liao)，就是將兩種或(huo)兩種以上的(de)天然(ran)礦藏(zang)質(zhi)料(liao)或(huo)化工(gong)質(zhi)料(liao)或(huo)廢棄(qi)物(wu)，通過配(pei)料(liao)、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅燒或(huo)電熔等工(gong)藝進程，合(he)成(cheng)(cheng)鎂鐵鈣砂制(zhi)取必定(ding)化學礦藏(zang)組成(cheng)(cheng)和(he)物(wu)理性能的(de)耐(nai)火(huo)質(zhi)料(liao)。組成(cheng)(cheng)耐(nai)火(huo)質(zhi)料(liao)的(de)品種繁復(fu)，組成(cheng)(cheng)辦法(fa)多(duo)種多(duo)樣(yang)，大體簡略介(jie)紹(shao)：

 純化(hua)工(gong)質(zhi)(zhi)料(liao)之間組成(cheng)耐火質(zhi)(zhi)料(liao)，如(ru)用工(gong)業氧化(hua)鋁(lv)(lv)與(yu)鈦白粉(fen)組成(cheng)鈦酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉(fen)與(yu)氮(dan)氣化(hua)合組成(cheng)AIN(氮(dan)化(hua)鋁(lv)(lv));工(gong)業氧化(hua)鋁(lv)(lv)與(yu)高純超細的氮(dan)化(hua)鋁(lv)(lv)粉(fen)組成(cheng)Alon(阿隆);用輕質(zhi)(zhi)碳酸(suan)鈣(gai)與(yu)工(gong)業氧化(hua)鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)學(xue)計量比例配料(liao)，組成(cheng)六(liu)鋁(lv)(lv)酸(suan)鈣(gai);用鈦白粉(fen)和(he)金屬鋁(lv)(lv)粉(fen)在流動氨氣效果下，原位生成(cheng)Al?O?-TiN復相資(zi)料(liao)等。

所謂(wei)組成(cheng)(cheng)耐火質料，就是將(jiang)兩種或兩種以上的(de)(de)天然(ran)礦(kuang)藏質料或化工質料或廢棄物，通過配料、粉碎，磨細，混合，成(cheng)(cheng)型，煅燒或電熔等(deng)工藝進程(cheng)，合成(cheng)(cheng)鎂鐵鈣砂制取必定(ding)化學礦(kuang)藏組成(cheng)(cheng)和物理性能(neng)的(de)(de)耐火質料。
