 鎂鈣砂

 可用天然礦藏質料(liao)本身之間的檔(dang)次(ci)不(bu)同配(pei)料(liao)組(zu)成(cheng),如莫(mo)來石(shi)(shi)(shi)(shi),也可不(bu)同天然礦藏質料(liao)配(pei)料(liao)組(zu)成(cheng),如用高鋁礬土與鋯(gao)英石(shi)(shi)(shi)(shi)精(jing)礦組(zu)成(cheng)鋯(gao)莫(mo)來石(shi)(shi)(shi)(shi);高鋁礬土與菱(ling)鎂(mei)(mei)礦組(zu)成(cheng)鋁鎂(mei)(mei)尖晶石(shi)(shi)(shi)(shi);菱(ling)鎂(mei)(mei)礦與白云石(shi)(shi)(shi)(shi)組(zu)成(cheng)鎂(mei)(mei)鈣砂;用高鈣菱(ling)鎂(mei)(mei)礦與鐵精(jing)礦配(pei)料(liao)組(zu)成(cheng)鎂(mei)(mei)鐵鈣砂;菱(ling)鎂(mei)(mei)礦與鋯(gao)英石(shi)(shi)(shi)(shi)組(zu)成(cheng)鎂(mei)(mei)鋯(gao)砂;葉(xie)蠟石(shi)(shi)(shi)(shi)與滑石(shi)(shi)(shi)(shi)組(zu)成(cheng)堇青(qing)石(shi)(shi)(shi)(shi);用菱(ling)鎂(mei)(mei)礦與二級高鋁礬土熟料(liao)配(pei)料(liao),焦炭作為還原劑,通過(guo)碳熱(re)還原氮化組(zu)成(cheng)Sialon—尖晶石(shi)(shi)(shi)(shi)復相資料(liao);藍晶石(shi)(shi)(shi)(shi)與石(shi)(shi)(shi)(shi)墨(mo)配(pei)料(liao),原位組(zu)成(cheng)AlN—SiC復相資料(liao)等。

所謂組(zu)(zu)成(cheng)耐(nai)火質(zhi)(zhi)料(liao)(liao),就是(shi)將兩種或兩種以上的天然(ran)礦藏質(zhi)(zhi)料(liao)(liao)或化工(gong)質(zhi)(zhi)料(liao)(liao)或廢棄物(wu),通過配料(liao)(liao)、粉碎,磨細,混合(he),成(cheng)型(xing),煅燒或電熔等工(gong)藝進程,合(he)成(cheng)鎂鐵鈣(gai)砂(sha)制(zhi)取(qu)必定化學礦藏組(zu)(zu)成(cheng)和物(wu)理性能的耐(nai)火質(zhi)(zhi)料(liao)(liao)。組(zu)(zu)成(cheng)耐(nai)火質(zhi)(zhi)料(liao)(liao)的品種繁復,組(zu)(zu)成(cheng)辦法(fa)多(duo)種多(duo)樣,大體簡(jian)略介紹:

 純(chun)化(hua)(hua)工質料(liao)之間組成(cheng)耐火質料(liao),如用(yong)工業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)與(yu)鈦白(bai)粉(fen)組成(cheng)鈦酸(suan)鋁(lv)(lv);鋁(lv)(lv)粉(fen)與(yu)氮(dan)(dan)氣化(hua)(hua)合組成(cheng)AIN(氮(dan)(dan)化(hua)(hua)鋁(lv)(lv));工業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv)與(yu)高純(chun)超(chao)細(xi)的氮(dan)(dan)化(hua)(hua)鋁(lv)(lv)粉(fen)組成(cheng)Alon(阿隆(long));用(yong)輕質碳酸(suan)鈣(gai)與(yu)工業(ye)氧(yang)化(hua)(hua)鋁(lv)(lv),按CA6的CaO與(yu)Al?O?的化(hua)(hua)學計量(liang)比例(li)配(pei)料(liao),組成(cheng)六鋁(lv)(lv)酸(suan)鈣(gai);用(yong)鈦白(bai)粉(fen)和金屬鋁(lv)(lv)粉(fen)在流(liu)動(dong)氨氣效果(guo)下,原位生(sheng)成(cheng)Al?O?-TiN復(fu)相資料(liao)等。

所(suo)謂組成耐火質(zhi)料(liao),就(jiu)是將兩種(zhong)或(huo)(huo)兩種(zhong)以上的天然礦藏(zang)質(zhi)料(liao)或(huo)(huo)化工(gong)質(zhi)料(liao)或(huo)(huo)廢棄物(wu),通過配料(liao)、粉碎,磨細,混合,成型,煅燒或(huo)(huo)電(dian)熔等(deng)工(gong)藝(yi)進程,合成鎂鐵鈣砂制取必定化學礦藏(zang)組成和物(wu)理(li)性能的耐火質(zhi)料(liao)。
