所謂組(zu)成耐火質(zhi)料，就是(shi)將兩種或兩種以(yi)上的天然礦藏(zang)質(zhi)料或化工(gong)質(zhi)料或廢棄物，通過配(pei)料、粉(fen)碎，磨細，混(hun)合(he)，成型，煅燒或電熔等工(gong)藝進程，合(he)成鎂鐵鈣砂制取必定化學礦藏(zang)組(zu)成和物理性能的耐火質(zhi)料。組(zu)成耐火質(zhi)料的品種繁復，組(zu)成辦法多種多樣，大(da)體簡(jian)略介紹：

 純化(hua)(hua)(hua)工(gong)質(zhi)(zhi)料之間組(zu)成(cheng)耐火質(zhi)(zhi)料，如(ru)用(yong)工(gong)業氧化(hua)(hua)(hua)鋁(lv)(lv)與(yu)鈦(tai)(tai)白粉(fen)(fen)(fen)組(zu)成(cheng)鈦(tai)(tai)酸鋁(lv)(lv);鋁(lv)(lv)粉(fen)(fen)(fen)與(yu)氮氣(qi)化(hua)(hua)(hua)合組(zu)成(cheng)AIN(氮化(hua)(hua)(hua)鋁(lv)(lv));工(gong)業氧化(hua)(hua)(hua)鋁(lv)(lv)與(yu)高純超(chao)細的氮化(hua)(hua)(hua)鋁(lv)(lv)粉(fen)(fen)(fen)組(zu)成(cheng)Alon(阿隆(long));用(yong)輕(qing)質(zhi)(zhi)碳酸鈣(gai)與(yu)工(gong)業氧化(hua)(hua)(hua)鋁(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)(hua)學計量比例配料，組(zu)成(cheng)六鋁(lv)(lv)酸鈣(gai);用(yong)鈦(tai)(tai)白粉(fen)(fen)(fen)和金屬鋁(lv)(lv)粉(fen)(fen)(fen)在流動氨氣(qi)效果下，原(yuan)位生(sheng)成(cheng)Al?O?-TiN復相資(zi)料等(deng)。

所謂組(zu)成(cheng)(cheng)耐(nai)火(huo)質(zhi)(zhi)料，就是將兩種(zhong)或(huo)兩種(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(wu)，通過(guo)配(pei)料、粉(fen)碎，磨細，混(hun)合，成(cheng)(cheng)型，煅燒或(huo)電(dian)熔等工(gong)藝進程，合成(cheng)(cheng)鎂(mei)鐵鈣砂制取必定化學(xue)礦藏組(zu)成(cheng)(cheng)和物(wu)理(li)性能(neng)的耐(nai)火(huo)質(zhi)(zhi)料。
