 鎂鈣砂

 可(ke)用天然礦藏質(zhi)(zhi)料本(ben)身之間的檔次不(bu)(bu)同配(pei)料組(zu)成(cheng),如莫來石(shi)(shi),也可(ke)不(bu)(bu)同天然礦藏質(zhi)(zhi)料配(pei)料組(zu)成(cheng),如用高(gao)鋁礬(fan)土與(yu)鋯英石(shi)(shi)精(jing)礦組(zu)成(cheng)鋯莫來石(shi)(shi);高(gao)鋁礬(fan)土與(yu)菱鎂(mei)礦組(zu)成(cheng)鋁鎂(mei)尖(jian)晶(jing)石(shi)(shi);菱鎂(mei)礦與(yu)白(bai)云石(shi)(shi)組(zu)成(cheng)鎂(mei)鈣(gai)砂(sha)(sha);用高(gao)鈣(gai)菱鎂(mei)礦與(yu)鐵(tie)精(jing)礦配(pei)料組(zu)成(cheng)鎂(mei)鐵(tie)鈣(gai)砂(sha)(sha);菱鎂(mei)礦與(yu)鋯英石(shi)(shi)組(zu)成(cheng)鎂(mei)鋯砂(sha)(sha);葉(xie)蠟(la)石(shi)(shi)與(yu)滑(hua)石(shi)(shi)組(zu)成(cheng)堇青石(shi)(shi);用菱鎂(mei)礦與(yu)二級(ji)高(gao)鋁礬(fan)土熟料配(pei)料,焦炭作(zuo)為還(huan)原劑,通過碳熱還(huan)原氮化組(zu)成(cheng)Sialon—尖(jian)晶(jing)石(shi)(shi)復相資(zi)料;藍晶(jing)石(shi)(shi)與(yu)石(shi)(shi)墨配(pei)料,原位(wei)組(zu)成(cheng)AlN—SiC復相資(zi)料等。

所謂組成耐火(huo)質(zhi)料(liao)(liao)(liao)(liao),就是將兩種(zhong)或(huo)兩種(zhong)以上的天(tian)然(ran)礦藏(zang)(zang)質(zhi)料(liao)(liao)(liao)(liao)或(huo)化工(gong)質(zhi)料(liao)(liao)(liao)(liao)或(huo)廢棄物,通(tong)過配料(liao)(liao)(liao)(liao)、粉碎,磨細,混合(he),成型,煅(duan)燒或(huo)電熔(rong)等工(gong)藝進程(cheng),合(he)成鎂鐵鈣砂制(zhi)取必定化學礦藏(zang)(zang)組成和物理性能的耐火(huo)質(zhi)料(liao)(liao)(liao)(liao)。組成耐火(huo)質(zhi)料(liao)(liao)(liao)(liao)的品種(zhong)繁復,組成辦法多(duo)種(zhong)多(duo)樣(yang),大(da)體簡略介紹:

 純化(hua)(hua)工(gong)(gong)質料之(zhi)間組(zu)(zu)成(cheng)耐火質料,如用(yong)工(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv)與(yu)鈦(tai)白(bai)粉(fen)(fen)組(zu)(zu)成(cheng)鈦(tai)酸(suan)(suan)鋁(lv);鋁(lv)粉(fen)(fen)與(yu)氮(dan)(dan)氣(qi)化(hua)(hua)合組(zu)(zu)成(cheng)AIN(氮(dan)(dan)化(hua)(hua)鋁(lv));工(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv)與(yu)高(gao)純超細的(de)(de)氮(dan)(dan)化(hua)(hua)鋁(lv)粉(fen)(fen)組(zu)(zu)成(cheng)Alon(阿隆(long));用(yong)輕質碳酸(suan)(suan)鈣與(yu)工(gong)(gong)業(ye)氧(yang)化(hua)(hua)鋁(lv),按CA6的(de)(de)CaO與(yu)Al?O?的(de)(de)化(hua)(hua)學(xue)計量比例配料,組(zu)(zu)成(cheng)六鋁(lv)酸(suan)(suan)鈣;用(yong)鈦(tai)白(bai)粉(fen)(fen)和(he)金屬鋁(lv)粉(fen)(fen)在流動氨(an)氣(qi)效(xiao)果下,原(yuan)位生(sheng)成(cheng)Al?O?-TiN復相資料等。

所(suo)謂組成(cheng)耐火(huo)質(zhi)料(liao),就是(shi)將兩(liang)種或(huo)兩(liang)種以(yi)上的天然礦藏質(zhi)料(liao)或(huo)化(hua)工(gong)質(zhi)料(liao)或(huo)廢(fei)棄物(wu)(wu),通過配料(liao)、粉碎,磨(mo)細,混合(he),成(cheng)型(xing),煅(duan)燒或(huo)電熔等工(gong)藝進程,合(he)成(cheng)鎂鐵(tie)鈣(gai)砂(sha)制(zhi)取必定化(hua)學礦藏組成(cheng)和物(wu)(wu)理性能(neng)的耐火(huo)質(zhi)料(liao)。
