所謂組(zu)成(cheng)(cheng)耐火質料，就是將兩種(zhong)或(huo)(huo)兩種(zhong)以上(shang)的(de)天然礦藏(zang)(zang)質料或(huo)(huo)化(hua)(hua)工(gong)(gong)質料或(huo)(huo)廢棄物，通(tong)過配料、粉碎，磨細，混合(he)，成(cheng)(cheng)型，煅燒或(huo)(huo)電熔等工(gong)(gong)藝進程，合(he)成(cheng)(cheng)鎂鐵鈣砂制取必定化(hua)(hua)學(xue)礦藏(zang)(zang)組(zu)成(cheng)(cheng)和物理性能的(de)耐火質料。組(zu)成(cheng)(cheng)耐火質料的(de)品種(zhong)繁復，組(zu)成(cheng)(cheng)辦法多(duo)(duo)種(zhong)多(duo)(duo)樣，大體簡略介紹：

 純化(hua)(hua)工(gong)質(zhi)料(liao)之間組成耐火質(zhi)料(liao)，如用工(gong)業(ye)氧(yang)化(hua)(hua)鋁與(yu)(yu)鈦白粉組成鈦酸(suan)鋁;鋁粉與(yu)(yu)氮氣化(hua)(hua)合組成AIN(氮化(hua)(hua)鋁);工(gong)業(ye)氧(yang)化(hua)(hua)鋁與(yu)(yu)高純超細(xi)的(de)氮化(hua)(hua)鋁粉組成Alon(阿隆);用輕質(zhi)碳酸(suan)鈣(gai)(gai)與(yu)(yu)工(gong)業(ye)氧(yang)化(hua)(hua)鋁，按CA6的(de)CaO與(yu)(yu)Al?O?的(de)化(hua)(hua)學計量比例(li)配料(liao)，組成六鋁酸(suan)鈣(gai)(gai);用鈦白粉和金屬鋁粉在流動氨氣效(xiao)果下，原位生成Al?O?-TiN復相資(zi)料(liao)等。

所謂組(zu)成(cheng)耐火質(zhi)(zhi)料，就是將兩種(zhong)或(huo)兩種(zhong)以上的天然(ran)礦(kuang)(kuang)藏(zang)質(zhi)(zhi)料或(huo)化工(gong)(gong)質(zhi)(zhi)料或(huo)廢棄(qi)物，通(tong)過配料、粉碎，磨細，混(hun)合(he)，成(cheng)型(xing)，煅燒(shao)或(huo)電(dian)熔等工(gong)(gong)藝進程，合(he)成(cheng)鎂鐵鈣砂制取必定化學礦(kuang)(kuang)藏(zang)組(zu)成(cheng)和物理性能的耐火質(zhi)(zhi)料。
