 鎂鈣砂

 可用(yong)天然礦(kuang)(kuang)藏質(zhi)料(liao)(liao)(liao)本身(shen)之間的檔次不同配(pei)料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng),如莫(mo)來石(shi)(shi)(shi)(shi),也(ye)可不同天然礦(kuang)(kuang)藏質(zhi)料(liao)(liao)(liao)配(pei)料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng),如用(yong)高鋁礬(fan)土與鋯英石(shi)(shi)(shi)(shi)精(jing)礦(kuang)(kuang)組(zu)(zu)成(cheng)(cheng)鋯莫(mo)來石(shi)(shi)(shi)(shi);高鋁礬(fan)土與菱鎂(mei)(mei)礦(kuang)(kuang)組(zu)(zu)成(cheng)(cheng)鋁鎂(mei)(mei)尖晶(jing)(jing)石(shi)(shi)(shi)(shi);菱鎂(mei)(mei)礦(kuang)(kuang)與白云石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)鎂(mei)(mei)鈣砂;用(yong)高鈣菱鎂(mei)(mei)礦(kuang)(kuang)與鐵(tie)(tie)精(jing)礦(kuang)(kuang)配(pei)料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)鎂(mei)(mei)鐵(tie)(tie)鈣砂;菱鎂(mei)(mei)礦(kuang)(kuang)與鋯英石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)鎂(mei)(mei)鋯砂;葉蠟石(shi)(shi)(shi)(shi)與滑(hua)石(shi)(shi)(shi)(shi)組(zu)(zu)成(cheng)(cheng)堇(jin)青(qing)石(shi)(shi)(shi)(shi);用(yong)菱鎂(mei)(mei)礦(kuang)(kuang)與二級高鋁礬(fan)土熟料(liao)(liao)(liao)配(pei)料(liao)(liao)(liao),焦炭作為還原劑,通過碳熱(re)還原氮化組(zu)(zu)成(cheng)(cheng)Sialon—尖晶(jing)(jing)石(shi)(shi)(shi)(shi)復(fu)相資(zi)料(liao)(liao)(liao);藍晶(jing)(jing)石(shi)(shi)(shi)(shi)與石(shi)(shi)(shi)(shi)墨配(pei)料(liao)(liao)(liao),原位組(zu)(zu)成(cheng)(cheng)AlN—SiC復(fu)相資(zi)料(liao)(liao)(liao)等。

所謂組成(cheng)耐火(huo)質料,就是(shi)將兩種(zhong)(zhong)或(huo)(huo)兩種(zhong)(zhong)以上(shang)的天然礦(kuang)藏質料或(huo)(huo)化工質料或(huo)(huo)廢棄物,通過配料、粉碎,磨(mo)細,混合,成(cheng)型,煅燒或(huo)(huo)電熔等(deng)工藝進程(cheng),合成(cheng)鎂鐵鈣(gai)砂制(zhi)取必定化學(xue)礦(kuang)藏組成(cheng)和物理性能的耐火(huo)質料。組成(cheng)耐火(huo)質料的品種(zhong)(zhong)繁復,組成(cheng)辦法多(duo)種(zhong)(zhong)多(duo)樣,大體簡略(lve)介(jie)紹:

 純化(hua)工質(zhi)料(liao)之(zhi)間組(zu)成(cheng)耐火質(zhi)料(liao),如用工業氧(yang)化(hua)鋁(lv)(lv)與(yu)鈦白(bai)粉組(zu)成(cheng)鈦酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉與(yu)氮(dan)(dan)氣化(hua)合組(zu)成(cheng)AIN(氮(dan)(dan)化(hua)鋁(lv)(lv));工業氧(yang)化(hua)鋁(lv)(lv)與(yu)高純超細的氮(dan)(dan)化(hua)鋁(lv)(lv)粉組(zu)成(cheng)Alon(阿隆);用輕質(zhi)碳酸(suan)鈣(gai)與(yu)工業氧(yang)化(hua)鋁(lv)(lv),按CA6的CaO與(yu)Al?O?的化(hua)學計量比(bi)例配(pei)料(liao),組(zu)成(cheng)六鋁(lv)(lv)酸(suan)鈣(gai);用鈦白(bai)粉和金屬鋁(lv)(lv)粉在流(liu)動氨氣效果(guo)下,原位生成(cheng)Al?O?-TiN復相資料(liao)等(deng)。

所謂組成(cheng)(cheng)耐火質料(liao),就是將(jiang)兩種(zhong)或(huo)(huo)兩種(zhong)以(yi)上的天然礦藏質料(liao)或(huo)(huo)化(hua)工(gong)質料(liao)或(huo)(huo)廢棄物(wu),通過配料(liao)、粉碎(sui),磨細,混合,成(cheng)(cheng)型,煅燒或(huo)(huo)電熔等工(gong)藝進程(cheng),合成(cheng)(cheng)鎂(mei)鐵鈣砂(sha)制取必定化(hua)學礦藏組成(cheng)(cheng)和(he)物(wu)理性能的耐火質料(liao)。
