 鎂鈣砂

 可用天(tian)然(ran)礦(kuang)藏質料(liao)(liao)本身之間的檔次不同配(pei)(pei)料(liao)(liao)組(zu)成(cheng)(cheng),如莫(mo)來(lai)石(shi)(shi)(shi)(shi),也可不同天(tian)然(ran)礦(kuang)藏質料(liao)(liao)配(pei)(pei)料(liao)(liao)組(zu)成(cheng)(cheng),如用高(gao)(gao)鋁(lv)(lv)礬土(tu)與(yu)(yu)(yu)鋯(gao)(gao)英(ying)石(shi)(shi)(shi)(shi)精礦(kuang)組(zu)成(cheng)(cheng)鋯(gao)(gao)莫(mo)來(lai)石(shi)(shi)(shi)(shi);高(gao)(gao)鋁(lv)(lv)礬土(tu)與(yu)(yu)(yu)菱鎂(mei)(mei)礦(kuang)組(zu)成(cheng)(cheng)鋁(lv)(lv)鎂(mei)(mei)尖晶(jing)石(shi)(shi)(shi)(shi);菱鎂(mei)(mei)礦(kuang)與(yu)(yu)(yu)白云石(shi)(shi)(shi)(shi)組(zu)成(cheng)(cheng)鎂(mei)(mei)鈣砂;用高(gao)(gao)鈣菱鎂(mei)(mei)礦(kuang)與(yu)(yu)(yu)鐵精礦(kuang)配(pei)(pei)料(liao)(liao)組(zu)成(cheng)(cheng)鎂(mei)(mei)鐵鈣砂;菱鎂(mei)(mei)礦(kuang)與(yu)(yu)(yu)鋯(gao)(gao)英(ying)石(shi)(shi)(shi)(shi)組(zu)成(cheng)(cheng)鎂(mei)(mei)鋯(gao)(gao)砂;葉蠟石(shi)(shi)(shi)(shi)與(yu)(yu)(yu)滑(hua)石(shi)(shi)(shi)(shi)組(zu)成(cheng)(cheng)堇青石(shi)(shi)(shi)(shi);用菱鎂(mei)(mei)礦(kuang)與(yu)(yu)(yu)二級(ji)高(gao)(gao)鋁(lv)(lv)礬土(tu)熟料(liao)(liao)配(pei)(pei)料(liao)(liao),焦(jiao)炭作為還原劑,通過碳熱還原氮化組(zu)成(cheng)(cheng)Sialon—尖晶(jing)石(shi)(shi)(shi)(shi)復相(xiang)資料(liao)(liao);藍(lan)晶(jing)石(shi)(shi)(shi)(shi)與(yu)(yu)(yu)石(shi)(shi)(shi)(shi)墨配(pei)(pei)料(liao)(liao),原位組(zu)成(cheng)(cheng)AlN—SiC復相(xiang)資料(liao)(liao)等(deng)。

所(suo)謂組(zu)成(cheng)(cheng)(cheng)耐火質料(liao)(liao),就是(shi)將兩種(zhong)或兩種(zhong)以上(shang)的(de)(de)天然礦藏質料(liao)(liao)或化工(gong)質料(liao)(liao)或廢棄物,通過配料(liao)(liao)、粉碎,磨細,混合,成(cheng)(cheng)(cheng)型,煅燒或電熔等(deng)工(gong)藝進程,合成(cheng)(cheng)(cheng)鎂鐵鈣砂制取必定(ding)化學(xue)礦藏組(zu)成(cheng)(cheng)(cheng)和物理性能的(de)(de)耐火質料(liao)(liao)。組(zu)成(cheng)(cheng)(cheng)耐火質料(liao)(liao)的(de)(de)品種(zhong)繁復,組(zu)成(cheng)(cheng)(cheng)辦法多種(zhong)多樣,大體簡(jian)略介紹:

 純(chun)化(hua)(hua)(hua)工(gong)質(zhi)料(liao)之間(jian)組(zu)成(cheng)耐火質(zhi)料(liao),如用工(gong)業(ye)氧化(hua)(hua)(hua)鋁(lv)與(yu)鈦白粉(fen)組(zu)成(cheng)鈦酸鋁(lv);鋁(lv)粉(fen)與(yu)氮(dan)(dan)氣化(hua)(hua)(hua)合組(zu)成(cheng)AIN(氮(dan)(dan)化(hua)(hua)(hua)鋁(lv));工(gong)業(ye)氧化(hua)(hua)(hua)鋁(lv)與(yu)高純(chun)超細的氮(dan)(dan)化(hua)(hua)(hua)鋁(lv)粉(fen)組(zu)成(cheng)Alon(阿隆);用輕質(zhi)碳(tan)酸鈣與(yu)工(gong)業(ye)氧化(hua)(hua)(hua)鋁(lv),按CA6的CaO與(yu)Al?O?的化(hua)(hua)(hua)學計量比例配料(liao),組(zu)成(cheng)六鋁(lv)酸鈣;用鈦白粉(fen)和(he)金(jin)屬鋁(lv)粉(fen)在流動氨氣效果(guo)下,原位生成(cheng)Al?O?-TiN復相(xiang)資料(liao)等。

所謂組成(cheng)耐火質料,就是將兩(liang)種或兩(liang)種以(yi)上(shang)的(de)天然礦藏質料或化工質料或廢棄物,通過配料、粉碎,磨細,混合,成(cheng)型(xing),煅燒或電熔等工藝進(jin)程,合成(cheng)鎂(mei)鐵(tie)鈣砂制取必定化學(xue)礦藏組成(cheng)和(he)物理性能的(de)耐火質料。
