所謂組(zu)成(cheng)耐(nai)火質(zhi)料，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以(yi)上的(de)天然礦(kuang)藏質(zhi)料或(huo)(huo)化工(gong)質(zhi)料或(huo)(huo)廢(fei)棄(qi)物，通過(guo)配料、粉碎(sui)，磨細，混合，成(cheng)型，煅燒或(huo)(huo)電熔等工(gong)藝進程，合成(cheng)鎂鐵鈣砂制取必定化學(xue)礦(kuang)藏組(zu)成(cheng)和物理性能(neng)的(de)耐(nai)火質(zhi)料。組(zu)成(cheng)耐(nai)火質(zhi)料的(de)品(pin)種(zhong)繁復，組(zu)成(cheng)辦法多(duo)種(zhong)多(duo)樣，大體簡略介紹：

 純化(hua)(hua)工質料(liao)之間組(zu)成(cheng)(cheng)耐火質料(liao)，如用(yong)工業氧化(hua)(hua)鋁(lv)(lv)與(yu)鈦(tai)(tai)白粉(fen)(fen)組(zu)成(cheng)(cheng)鈦(tai)(tai)酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)(fen)與(yu)氮(dan)氣(qi)化(hua)(hua)合組(zu)成(cheng)(cheng)AIN(氮(dan)化(hua)(hua)鋁(lv)(lv));工業氧化(hua)(hua)鋁(lv)(lv)與(yu)高(gao)純超細(xi)的氮(dan)化(hua)(hua)鋁(lv)(lv)粉(fen)(fen)組(zu)成(cheng)(cheng)Alon(阿隆(long));用(yong)輕質碳酸鈣與(yu)工業氧化(hua)(hua)鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)學計(ji)量比例(li)配料(liao)，組(zu)成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦(tai)(tai)白粉(fen)(fen)和金屬(shu)鋁(lv)(lv)粉(fen)(fen)在流動氨氣(qi)效果(guo)下，原(yuan)位生成(cheng)(cheng)Al?O?-TiN復相資料(liao)等。

所謂組成(cheng)耐火質料，就(jiu)是將兩(liang)種(zhong)或(huo)兩(liang)種(zhong)以(yi)上的(de)天然礦藏質料或(huo)化工質料或(huo)廢棄物(wu)，通過配料、粉碎，磨細，混合(he)，成(cheng)型，煅燒或(huo)電熔等工藝進程(cheng)，合(he)成(cheng)鎂鐵(tie)鈣砂制(zhi)取必定化學礦藏組成(cheng)和物(wu)理性能的(de)耐火質料。
