所謂組(zu)成(cheng)(cheng)(cheng)(cheng)耐火質料(liao)，就是將兩種(zhong)(zhong)或(huo)(huo)兩種(zhong)(zhong)以上的天然礦藏質料(liao)或(huo)(huo)化工質料(liao)或(huo)(huo)廢(fei)棄(qi)物(wu)，通過配料(liao)、粉碎(sui)，磨細，混合(he)(he)，成(cheng)(cheng)(cheng)(cheng)型(xing)，煅燒(shao)或(huo)(huo)電熔(rong)等工藝進(jin)程，合(he)(he)成(cheng)(cheng)(cheng)(cheng)鎂鐵鈣砂制取必定化學礦藏組(zu)成(cheng)(cheng)(cheng)(cheng)和物(wu)理性(xing)能的耐火質料(liao)。組(zu)成(cheng)(cheng)(cheng)(cheng)耐火質料(liao)的品種(zhong)(zhong)繁復，組(zu)成(cheng)(cheng)(cheng)(cheng)辦法(fa)多種(zhong)(zhong)多樣，大(da)體簡(jian)略(lve)介紹：

 純化(hua)工質料(liao)之間組成(cheng)(cheng)耐火質料(liao)，如(ru)用(yong)(yong)工業(ye)氧化(hua)鋁(lv)與(yu)鈦(tai)白粉(fen)組成(cheng)(cheng)鈦(tai)酸(suan)鋁(lv);鋁(lv)粉(fen)與(yu)氮(dan)氣化(hua)合組成(cheng)(cheng)AIN(氮(dan)化(hua)鋁(lv));工業(ye)氧化(hua)鋁(lv)與(yu)高(gao)純超(chao)細的氮(dan)化(hua)鋁(lv)粉(fen)組成(cheng)(cheng)Alon(阿隆);用(yong)(yong)輕質碳酸(suan)鈣與(yu)工業(ye)氧化(hua)鋁(lv)，按(an)CA6的CaO與(yu)Al?O?的化(hua)學計(ji)量比(bi)例配料(liao)，組成(cheng)(cheng)六鋁(lv)酸(suan)鈣;用(yong)(yong)鈦(tai)白粉(fen)和金屬鋁(lv)粉(fen)在流動氨氣效果下，原位生成(cheng)(cheng)Al?O?-TiN復相資料(liao)等。

所謂組成耐火(huo)質料，就是將兩種或(huo)兩種以(yi)上的天然礦(kuang)藏質料或(huo)化(hua)工質料或(huo)廢棄物，通過配料、粉碎，磨細，混(hun)合(he)(he)，成型，煅燒(shao)或(huo)電熔等工藝進程，合(he)(he)成鎂鐵鈣砂制(zhi)取必(bi)定化(hua)學礦(kuang)藏組成和物理性能的耐火(huo)質料。
