 鎂鈣砂

 可用(yong)天然(ran)礦藏質料(liao)(liao)(liao)本(ben)身之間的檔次(ci)不同(tong)配料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng),如莫(mo)來石(shi)(shi),也可不同(tong)天然(ran)礦藏質料(liao)(liao)(liao)配料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng),如用(yong)高鋁礬(fan)土與(yu)(yu)(yu)鋯(gao)(gao)英石(shi)(shi)精礦組(zu)(zu)成(cheng)(cheng)(cheng)鋯(gao)(gao)莫(mo)來石(shi)(shi);高鋁礬(fan)土與(yu)(yu)(yu)菱鎂礦組(zu)(zu)成(cheng)(cheng)(cheng)鋁鎂尖晶石(shi)(shi);菱鎂礦與(yu)(yu)(yu)白(bai)云(yun)石(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鈣(gai)(gai)砂;用(yong)高鈣(gai)(gai)菱鎂礦與(yu)(yu)(yu)鐵精礦配料(liao)(liao)(liao)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鐵鈣(gai)(gai)砂;菱鎂礦與(yu)(yu)(yu)鋯(gao)(gao)英石(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)鎂鋯(gao)(gao)砂;葉蠟石(shi)(shi)與(yu)(yu)(yu)滑石(shi)(shi)組(zu)(zu)成(cheng)(cheng)(cheng)堇青石(shi)(shi);用(yong)菱鎂礦與(yu)(yu)(yu)二級高鋁礬(fan)土熟料(liao)(liao)(liao)配料(liao)(liao)(liao),焦炭作為(wei)還(huan)原(yuan)劑(ji),通(tong)過碳熱(re)還(huan)原(yuan)氮化組(zu)(zu)成(cheng)(cheng)(cheng)Sialon—尖晶石(shi)(shi)復(fu)相資(zi)料(liao)(liao)(liao);藍晶石(shi)(shi)與(yu)(yu)(yu)石(shi)(shi)墨配料(liao)(liao)(liao),原(yuan)位組(zu)(zu)成(cheng)(cheng)(cheng)AlN—SiC復(fu)相資(zi)料(liao)(liao)(liao)等。

所謂組(zu)成(cheng)(cheng)(cheng)耐(nai)火(huo)質(zhi)(zhi)料(liao),就是將兩種(zhong)或兩種(zhong)以上的(de)天然礦藏質(zhi)(zhi)料(liao)或化工質(zhi)(zhi)料(liao)或廢棄(qi)物,通過配料(liao)、粉碎,磨細,混合(he),成(cheng)(cheng)(cheng)型,煅燒或電(dian)熔等(deng)工藝進(jin)程,合(he)成(cheng)(cheng)(cheng)鎂鐵鈣(gai)砂制取(qu)必定化學礦藏組(zu)成(cheng)(cheng)(cheng)和(he)物理性能的(de)耐(nai)火(huo)質(zhi)(zhi)料(liao)。組(zu)成(cheng)(cheng)(cheng)耐(nai)火(huo)質(zhi)(zhi)料(liao)的(de)品種(zhong)繁復,組(zu)成(cheng)(cheng)(cheng)辦法(fa)多種(zhong)多樣,大體簡略介紹:

 純化(hua)(hua)工質料(liao)之間組成耐火質料(liao),如用(yong)工業(ye)氧化(hua)(hua)鋁(lv)(lv)(lv)與(yu)鈦(tai)白粉組成鈦(tai)酸(suan)鋁(lv)(lv)(lv);鋁(lv)(lv)(lv)粉與(yu)氮(dan)氣化(hua)(hua)合組成AIN(氮(dan)化(hua)(hua)鋁(lv)(lv)(lv));工業(ye)氧化(hua)(hua)鋁(lv)(lv)(lv)與(yu)高純超細的(de)氮(dan)化(hua)(hua)鋁(lv)(lv)(lv)粉組成Alon(阿隆);用(yong)輕(qing)質碳酸(suan)鈣與(yu)工業(ye)氧化(hua)(hua)鋁(lv)(lv)(lv),按(an)CA6的(de)CaO與(yu)Al?O?的(de)化(hua)(hua)學計量比(bi)例配料(liao),組成六鋁(lv)(lv)(lv)酸(suan)鈣;用(yong)鈦(tai)白粉和金屬鋁(lv)(lv)(lv)粉在流動(dong)氨氣效果下(xia),原位生成Al?O?-TiN復(fu)相(xiang)資料(liao)等。

所謂組成(cheng)(cheng)耐火(huo)質(zhi)(zhi)(zhi)料(liao)(liao),就是(shi)將兩(liang)種或(huo)兩(liang)種以(yi)上的天(tian)然礦藏(zang)質(zhi)(zhi)(zhi)料(liao)(liao)或(huo)化工(gong)質(zhi)(zhi)(zhi)料(liao)(liao)或(huo)廢棄物,通過配(pei)料(liao)(liao)、粉碎(sui),磨細,混合,成(cheng)(cheng)型(xing),煅燒或(huo)電熔(rong)等(deng)工(gong)藝進(jin)程,合成(cheng)(cheng)鎂鐵鈣砂(sha)制取必(bi)定化學礦藏(zang)組成(cheng)(cheng)和物理(li)性能的耐火(huo)質(zhi)(zhi)(zhi)料(liao)(liao)。
