 可用(yong)(yong)(yong)天然(ran)礦藏質料本身之間(jian)的檔次不同(tong)配料組(zu)(zu)(zu)成，如莫(mo)來石(shi)(shi)(shi)，也可不同(tong)天然(ran)礦藏質料配料組(zu)(zu)(zu)成，如用(yong)(yong)(yong)高鋁礬土(tu)(tu)與(yu)鋯(gao)英石(shi)(shi)(shi)精礦組(zu)(zu)(zu)成鋯(gao)莫(mo)來石(shi)(shi)(shi);高鋁礬土(tu)(tu)與(yu)菱鎂(mei)(mei)(mei)(mei)礦組(zu)(zu)(zu)成鋁鎂(mei)(mei)(mei)(mei)尖(jian)晶石(shi)(shi)(shi);菱鎂(mei)(mei)(mei)(mei)礦與(yu)白云石(shi)(shi)(shi)組(zu)(zu)(zu)成鎂(mei)(mei)(mei)(mei)鈣砂(sha);用(yong)(yong)(yong)高鈣菱鎂(mei)(mei)(mei)(mei)礦與(yu)鐵精礦配料組(zu)(zu)(zu)成鎂(mei)(mei)(mei)(mei)鐵鈣砂(sha);菱鎂(mei)(mei)(mei)(mei)礦與(yu)鋯(gao)英石(shi)(shi)(shi)組(zu)(zu)(zu)成鎂(mei)(mei)(mei)(mei)鋯(gao)砂(sha);葉蠟石(shi)(shi)(shi)與(yu)滑(hua)石(shi)(shi)(shi)組(zu)(zu)(zu)成堇青石(shi)(shi)(shi);用(yong)(yong)(yong)菱鎂(mei)(mei)(mei)(mei)礦與(yu)二(er)級高鋁礬土(tu)(tu)熟料配料，焦炭作(zuo)為(wei)還(huan)原劑，通過碳熱還(huan)原氮(dan)化(hua)組(zu)(zu)(zu)成Sialon—尖(jian)晶石(shi)(shi)(shi)復(fu)相資料;藍晶石(shi)(shi)(shi)與(yu)石(shi)(shi)(shi)墨配料，原位組(zu)(zu)(zu)成AlN—SiC復(fu)相資料等。

所謂組成耐(nai)(nai)火質(zhi)料(liao)(liao)，就是將兩(liang)種(zhong)(zhong)或兩(liang)種(zhong)(zhong)以上的(de)天然(ran)礦藏質(zhi)料(liao)(liao)或化(hua)工質(zhi)料(liao)(liao)或廢棄(qi)物(wu)，通過配(pei)料(liao)(liao)、粉碎(sui)，磨(mo)細(xi)，混合(he)，成型，煅燒(shao)或電熔等工藝進程，合(he)成鎂(mei)鐵鈣砂制取必(bi)定化(hua)學(xue)礦藏組成和物(wu)理性(xing)能的(de)耐(nai)(nai)火質(zhi)料(liao)(liao)。組成耐(nai)(nai)火質(zhi)料(liao)(liao)的(de)品種(zhong)(zhong)繁復，組成辦法多(duo)種(zhong)(zhong)多(duo)樣，大體簡略介紹(shao)：

 純化(hua)(hua)工(gong)質(zhi)料(liao)之間組(zu)成(cheng)耐火質(zhi)料(liao)，如用(yong)工(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)(yu)鈦白粉組(zu)成(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉與(yu)(yu)氮(dan)氣(qi)化(hua)(hua)合組(zu)成(cheng)AIN(氮(dan)化(hua)(hua)鋁(lv)(lv));工(gong)業氧化(hua)(hua)鋁(lv)(lv)與(yu)(yu)高純超(chao)細的(de)氮(dan)化(hua)(hua)鋁(lv)(lv)粉組(zu)成(cheng)Alon(阿隆(long));用(yong)輕質(zhi)碳酸鈣與(yu)(yu)工(gong)業氧化(hua)(hua)鋁(lv)(lv)，按CA6的(de)CaO與(yu)(yu)Al?O?的(de)化(hua)(hua)學計量(liang)比例配料(liao)，組(zu)成(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白粉和金(jin)屬鋁(lv)(lv)粉在(zai)流動氨氣(qi)效果下，原位生(sheng)成(cheng)Al?O?-TiN復(fu)相資(zi)料(liao)等。

所謂組成耐(nai)火質料(liao)，就(jiu)是將兩(liang)種或(huo)兩(liang)種以上(shang)的天然礦藏質料(liao)或(huo)化(hua)工質料(liao)或(huo)廢棄物(wu)，通過配(pei)料(liao)、粉碎，磨細，混合，成型(xing)，煅燒(shao)或(huo)電(dian)熔(rong)等工藝進程(cheng)，合成鎂鐵鈣砂(sha)制取(qu)必定化(hua)學礦藏組成和物(wu)理性能的耐(nai)火質料(liao)。
