所(suo)謂組(zu)成(cheng)耐(nai)火質(zhi)(zhi)料(liao)(liao)，就是將兩(liang)種或兩(liang)種以上(shang)的天然礦藏質(zhi)(zhi)料(liao)(liao)或化(hua)工質(zhi)(zhi)料(liao)(liao)或廢棄物，通過配料(liao)(liao)、粉碎，磨細，混合，成(cheng)型，煅(duan)燒或電熔等工藝進程，合成(cheng)鎂鐵鈣砂制取必(bi)定化(hua)學(xue)礦藏組(zu)成(cheng)和物理性能的耐(nai)火質(zhi)(zhi)料(liao)(liao)。組(zu)成(cheng)耐(nai)火質(zhi)(zhi)料(liao)(liao)的品(pin)種繁(fan)復，組(zu)成(cheng)辦(ban)法(fa)多種多樣，大體簡略介紹：

 純化(hua)(hua)工(gong)質(zhi)料(liao)(liao)之間組(zu)成耐(nai)火質(zhi)料(liao)(liao)，如用(yong)工(gong)業(ye)氧(yang)(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)與(yu)鈦(tai)白(bai)(bai)粉組(zu)成鈦(tai)酸鋁(lv)(lv)(lv)(lv);鋁(lv)(lv)(lv)(lv)粉與(yu)氮氣化(hua)(hua)合組(zu)成AIN(氮化(hua)(hua)鋁(lv)(lv)(lv)(lv));工(gong)業(ye)氧(yang)(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)與(yu)高(gao)純超(chao)細的氮化(hua)(hua)鋁(lv)(lv)(lv)(lv)粉組(zu)成Alon(阿隆);用(yong)輕質(zhi)碳(tan)酸鈣與(yu)工(gong)業(ye)氧(yang)(yang)化(hua)(hua)鋁(lv)(lv)(lv)(lv)，按CA6的CaO與(yu)Al?O?的化(hua)(hua)學(xue)計量(liang)比(bi)例配料(liao)(liao)，組(zu)成六鋁(lv)(lv)(lv)(lv)酸鈣;用(yong)鈦(tai)白(bai)(bai)粉和金(jin)屬鋁(lv)(lv)(lv)(lv)粉在流動氨氣效果下，原位(wei)生成Al?O?-TiN復(fu)相資料(liao)(liao)等。

所(suo)謂組成耐(nai)火質(zhi)料，就(jiu)是將兩(liang)種(zhong)或(huo)(huo)兩(liang)種(zhong)以上的天然礦(kuang)藏(zang)(zang)質(zhi)料或(huo)(huo)化工(gong)(gong)質(zhi)料或(huo)(huo)廢棄物(wu)(wu)，通(tong)過配料、粉碎，磨(mo)細(xi)，混合，成型，煅燒(shao)或(huo)(huo)電熔等(deng)工(gong)(gong)藝進程(cheng)，合成鎂鐵鈣(gai)砂(sha)制取必定(ding)化學礦(kuang)藏(zang)(zang)組成和物(wu)(wu)理性能的耐(nai)火質(zhi)料。
