所(suo)謂組成耐火質(zhi)料(liao)，就是將兩種(zhong)或(huo)(huo)(huo)兩種(zhong)以(yi)上(shang)的天然(ran)礦(kuang)藏質(zhi)料(liao)或(huo)(huo)(huo)化(hua)工(gong)質(zhi)料(liao)或(huo)(huo)(huo)廢棄物(wu)，通過配料(liao)、粉碎，磨細，混(hun)合(he)，成型，煅燒或(huo)(huo)(huo)電(dian)熔等工(gong)藝進(jin)程，合(he)成鎂鐵鈣砂制取(qu)必定化(hua)學礦(kuang)藏組成和(he)物(wu)理性能(neng)的耐火質(zhi)料(liao)。組成耐火質(zhi)料(liao)的品(pin)種(zhong)繁復(fu)，組成辦法多(duo)(duo)種(zhong)多(duo)(duo)樣，大體簡(jian)略介紹：

 純化工(gong)(gong)質(zhi)料(liao)(liao)之間組成耐火(huo)質(zhi)料(liao)(liao)，如用(yong)工(gong)(gong)業氧化鋁與鈦(tai)白粉(fen)(fen)組成鈦(tai)酸(suan)鋁;鋁粉(fen)(fen)與氮氣化合組成AIN(氮化鋁);工(gong)(gong)業氧化鋁與高純超細的氮化鋁粉(fen)(fen)組成Alon(阿隆);用(yong)輕質(zhi)碳酸(suan)鈣(gai)與工(gong)(gong)業氧化鋁，按CA6的CaO與Al?O?的化學(xue)計量(liang)比例配(pei)料(liao)(liao)，組成六(liu)鋁酸(suan)鈣(gai);用(yong)鈦(tai)白粉(fen)(fen)和(he)金屬鋁粉(fen)(fen)在流動(dong)氨氣效果下(xia)，原位(wei)生成Al?O?-TiN復相資料(liao)(liao)等。

所謂(wei)組成(cheng)耐火質(zhi)料，就是將兩種或(huo)兩種以上(shang)的天然(ran)礦(kuang)藏(zang)質(zhi)料或(huo)化工質(zhi)料或(huo)廢棄物，通過配料、粉碎，磨細(xi)，混合(he)，成(cheng)型，煅燒(shao)或(huo)電熔等工藝進程，合(he)成(cheng)鎂鐵鈣(gai)砂制取必(bi)定化學(xue)礦(kuang)藏(zang)組成(cheng)和物理(li)性能的耐火質(zhi)料。
