 可(ke)用天(tian)(tian)然礦(kuang)藏(zang)質料(liao)(liao)(liao)(liao)本身之間(jian)的檔次(ci)不(bu)同(tong)配料(liao)(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng),如莫來(lai)石(shi)(shi)(shi),也可(ke)不(bu)同(tong)天(tian)(tian)然礦(kuang)藏(zang)質料(liao)(liao)(liao)(liao)配料(liao)(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng),如用高(gao)(gao)鋁礬(fan)土與(yu)(yu)(yu)鋯(gao)(gao)英石(shi)(shi)(shi)精礦(kuang)組(zu)(zu)成(cheng)(cheng)(cheng)鋯(gao)(gao)莫來(lai)石(shi)(shi)(shi);高(gao)(gao)鋁礬(fan)土與(yu)(yu)(yu)菱鎂礦(kuang)組(zu)(zu)成(cheng)(cheng)(cheng)鋁鎂尖晶(jing)石(shi)(shi)(shi);菱鎂礦(kuang)與(yu)(yu)(yu)白(bai)云石(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鈣砂;用高(gao)(gao)鈣菱鎂礦(kuang)與(yu)(yu)(yu)鐵精礦(kuang)配料(liao)(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鐵鈣砂;菱鎂礦(kuang)與(yu)(yu)(yu)鋯(gao)(gao)英石(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鋯(gao)(gao)砂;葉蠟石(shi)(shi)(shi)與(yu)(yu)(yu)滑石(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)堇青石(shi)(shi)(shi);用菱鎂礦(kuang)與(yu)(yu)(yu)二級高(gao)(gao)鋁礬(fan)土熟(shu)料(liao)(liao)(liao)(liao)配料(liao)(liao)(liao)(liao),焦炭作為還(huan)原劑(ji),通過碳熱還(huan)原氮(dan)化組(zu)(zu)成(cheng)(cheng)(cheng)Sialon—尖晶(jing)石(shi)(shi)(shi)復相(xiang)資料(liao)(liao)(liao)(liao);藍晶(jing)石(shi)(shi)(shi)與(yu)(yu)(yu)石(shi)(shi)(shi)墨(mo)配料(liao)(liao)(liao)(liao),原位組(zu)(zu)成(cheng)(cheng)(cheng)AlN—SiC復相(xiang)資料(liao)(liao)(liao)(liao)等。

所謂(wei)組(zu)成耐火(huo)質料(liao),就是將兩種(zhong)或兩種(zhong)以上的天然礦(kuang)藏質料(liao)或化工(gong)(gong)質料(liao)或廢棄物,通過配料(liao)、粉(fen)碎,磨(mo)細,混合,成型,煅燒或電熔(rong)等工(gong)(gong)藝進程,合成鎂(mei)鐵鈣砂制(zhi)取必定化學礦(kuang)藏組(zu)成和物理性(xing)能的耐火(huo)質料(liao)。組(zu)成耐火(huo)質料(liao)的品種(zhong)繁復(fu),組(zu)成辦法多(duo)種(zhong)多(duo)樣,大體(ti)簡略介紹:

 純化(hua)工(gong)質料(liao)之間組成耐火質料(liao),如(ru)用工(gong)業(ye)氧化(hua)鋁(lv)(lv)(lv)(lv)(lv)與鈦(tai)白粉組成鈦(tai)酸(suan)鋁(lv)(lv)(lv)(lv)(lv);鋁(lv)(lv)(lv)(lv)(lv)粉與氮氣(qi)化(hua)合組成AIN(氮化(hua)鋁(lv)(lv)(lv)(lv)(lv));工(gong)業(ye)氧化(hua)鋁(lv)(lv)(lv)(lv)(lv)與高純超細(xi)的氮化(hua)鋁(lv)(lv)(lv)(lv)(lv)粉組成Alon(阿隆);用輕(qing)質碳酸(suan)鈣與工(gong)業(ye)氧化(hua)鋁(lv)(lv)(lv)(lv)(lv),按CA6的CaO與Al?O?的化(hua)學計(ji)量比例配(pei)料(liao),組成六鋁(lv)(lv)(lv)(lv)(lv)酸(suan)鈣;用鈦(tai)白粉和(he)金屬(shu)鋁(lv)(lv)(lv)(lv)(lv)粉在流(liu)動氨氣(qi)效果下(xia),原位(wei)生成Al?O?-TiN復相資(zi)料(liao)等。

所謂(wei)組(zu)成(cheng)耐火質料(liao),就是(shi)將兩種或(huo)(huo)兩種以(yi)上的(de)天然礦(kuang)藏質料(liao)或(huo)(huo)化工質料(liao)或(huo)(huo)廢棄物,通過(guo)配料(liao)、粉碎,磨細,混合,成(cheng)型,煅燒或(huo)(huo)電熔等工藝進(jin)程,合成(cheng)鎂鐵鈣砂制取必(bi)定化學礦(kuang)藏組(zu)成(cheng)和物理性能的(de)耐火質料(liao)。
