所謂組成(cheng)耐(nai)火(huo)質料，就是將兩種或兩種以(yi)上的天(tian)然礦(kuang)藏質料或化(hua)工質料或廢棄物，通過配料、粉碎(sui)，磨細，混(hun)合(he)，成(cheng)型，煅燒或電熔等工藝進程，合(he)成(cheng)鎂鐵鈣(gai)砂制取必定化(hua)學礦(kuang)藏組成(cheng)和物理性(xing)能的耐(nai)火(huo)質料。組成(cheng)耐(nai)火(huo)質料的品種繁復，組成(cheng)辦(ban)法多(duo)種多(duo)樣(yang)，大體簡略介紹(shao)：

 純(chun)化(hua)工(gong)質(zhi)料(liao)(liao)之間組(zu)成耐火質(zhi)料(liao)(liao)，如用工(gong)業氧(yang)化(hua)鋁與鈦白粉組(zu)成鈦酸鋁;鋁粉與氮氣化(hua)合組(zu)成AIN(氮化(hua)鋁);工(gong)業氧(yang)化(hua)鋁與高純(chun)超細的氮化(hua)鋁粉組(zu)成Alon(阿隆);用輕質(zhi)碳酸鈣(gai)與工(gong)業氧(yang)化(hua)鋁，按CA6的CaO與Al?O?的化(hua)學計量比例配(pei)料(liao)(liao)，組(zu)成六(liu)鋁酸鈣(gai);用鈦白粉和金屬鋁粉在(zai)流動氨氣效果下，原位生(sheng)成Al?O?-TiN復相資(zi)料(liao)(liao)等(deng)。

所謂(wei)組成耐火質(zhi)(zhi)料(liao)(liao)(liao)(liao)，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以上的天然礦藏質(zhi)(zhi)料(liao)(liao)(liao)(liao)或(huo)(huo)化工(gong)質(zhi)(zhi)料(liao)(liao)(liao)(liao)或(huo)(huo)廢棄(qi)物(wu)，通過(guo)配(pei)料(liao)(liao)(liao)(liao)、粉碎，磨(mo)細，混合(he)，成型，煅燒或(huo)(huo)電熔等工(gong)藝(yi)進程，合(he)成鎂鐵鈣砂制取必定化學礦藏組成和物(wu)理性能的耐火質(zhi)(zhi)料(liao)(liao)(liao)(liao)。
