 鎂鈣砂

 可用(yong)天然礦(kuang)(kuang)藏質料(liao)(liao)(liao)本身之間的檔次不同(tong)配(pei)(pei)料(liao)(liao)(liao)組(zu)(zu)(zu)成(cheng),如(ru)莫(mo)來石(shi)(shi),也(ye)可不同(tong)天然礦(kuang)(kuang)藏質料(liao)(liao)(liao)配(pei)(pei)料(liao)(liao)(liao)組(zu)(zu)(zu)成(cheng),如(ru)用(yong)高鋁(lv)(lv)(lv)礬土(tu)與(yu)鋯(gao)(gao)英(ying)石(shi)(shi)精礦(kuang)(kuang)組(zu)(zu)(zu)成(cheng)鋯(gao)(gao)莫(mo)來石(shi)(shi);高鋁(lv)(lv)(lv)礬土(tu)與(yu)菱鎂礦(kuang)(kuang)組(zu)(zu)(zu)成(cheng)鋁(lv)(lv)(lv)鎂尖(jian)晶(jing)石(shi)(shi);菱鎂礦(kuang)(kuang)與(yu)白云石(shi)(shi)組(zu)(zu)(zu)成(cheng)鎂鈣砂;用(yong)高鈣菱鎂礦(kuang)(kuang)與(yu)鐵精礦(kuang)(kuang)配(pei)(pei)料(liao)(liao)(liao)組(zu)(zu)(zu)成(cheng)鎂鐵鈣砂;菱鎂礦(kuang)(kuang)與(yu)鋯(gao)(gao)英(ying)石(shi)(shi)組(zu)(zu)(zu)成(cheng)鎂鋯(gao)(gao)砂;葉蠟石(shi)(shi)與(yu)滑石(shi)(shi)組(zu)(zu)(zu)成(cheng)堇青(qing)石(shi)(shi);用(yong)菱鎂礦(kuang)(kuang)與(yu)二級(ji)高鋁(lv)(lv)(lv)礬土(tu)熟料(liao)(liao)(liao)配(pei)(pei)料(liao)(liao)(liao),焦炭作為還(huan)原(yuan)劑,通(tong)過碳熱還(huan)原(yuan)氮化(hua)組(zu)(zu)(zu)成(cheng)Sialon—尖(jian)晶(jing)石(shi)(shi)復相資(zi)料(liao)(liao)(liao);藍晶(jing)石(shi)(shi)與(yu)石(shi)(shi)墨配(pei)(pei)料(liao)(liao)(liao),原(yuan)位(wei)組(zu)(zu)(zu)成(cheng)AlN—SiC復相資(zi)料(liao)(liao)(liao)等。

所謂組(zu)成耐火(huo)質料(liao),就是(shi)將兩種(zhong)(zhong)(zhong)或(huo)兩種(zhong)(zhong)(zhong)以上的(de)天然礦藏(zang)質料(liao)或(huo)化工(gong)質料(liao)或(huo)廢(fei)棄物(wu),通過配料(liao)、粉碎,磨細,混合,成型(xing),煅燒或(huo)電熔等工(gong)藝進程,合成鎂鐵鈣砂制取必定化學礦藏(zang)組(zu)成和物(wu)理(li)性能的(de)耐火(huo)質料(liao)。組(zu)成耐火(huo)質料(liao)的(de)品種(zhong)(zhong)(zhong)繁復,組(zu)成辦法(fa)多(duo)種(zhong)(zhong)(zhong)多(duo)樣,大體簡略介紹:

 純化(hua)(hua)(hua)工(gong)(gong)質料之(zhi)間組(zu)(zu)成(cheng)(cheng)耐火質料,如(ru)用(yong)工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv)與(yu)(yu)鈦白粉組(zu)(zu)成(cheng)(cheng)鈦酸鋁(lv)(lv);鋁(lv)(lv)粉與(yu)(yu)氮氣化(hua)(hua)(hua)合組(zu)(zu)成(cheng)(cheng)AIN(氮化(hua)(hua)(hua)鋁(lv)(lv));工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv)與(yu)(yu)高純超細的(de)(de)氮化(hua)(hua)(hua)鋁(lv)(lv)粉組(zu)(zu)成(cheng)(cheng)Alon(阿隆(long));用(yong)輕質碳(tan)酸鈣與(yu)(yu)工(gong)(gong)業(ye)氧(yang)(yang)化(hua)(hua)(hua)鋁(lv)(lv),按CA6的(de)(de)CaO與(yu)(yu)Al?O?的(de)(de)化(hua)(hua)(hua)學計量(liang)比例配料,組(zu)(zu)成(cheng)(cheng)六鋁(lv)(lv)酸鈣;用(yong)鈦白粉和金屬鋁(lv)(lv)粉在流動氨氣效果下,原位生成(cheng)(cheng)Al?O?-TiN復相資料等。

所謂組成(cheng)耐火質(zhi)料(liao)(liao)(liao),就(jiu)是將兩種(zhong)或兩種(zhong)以上的天然(ran)礦(kuang)藏(zang)質(zhi)料(liao)(liao)(liao)或化(hua)(hua)工質(zhi)料(liao)(liao)(liao)或廢棄物,通過配料(liao)(liao)(liao)、粉碎,磨細,混(hun)合,成(cheng)型,煅燒或電熔等工藝進(jin)程,合成(cheng)鎂鐵鈣砂制取必(bi)定(ding)化(hua)(hua)學礦(kuang)藏(zang)組成(cheng)和物理性能(neng)的耐火質(zhi)料(liao)(liao)(liao)。
