 鎂鈣砂

 可(ke)用天(tian)然礦藏質料(liao)(liao)本身之(zhi)間的檔次不同配(pei)料(liao)(liao)組成(cheng)(cheng),如莫來石(shi)(shi)(shi)(shi),也(ye)可(ke)不同天(tian)然礦藏質料(liao)(liao)配(pei)料(liao)(liao)組成(cheng)(cheng),如用高鋁(lv)礬土與(yu)鋯英石(shi)(shi)(shi)(shi)精礦組成(cheng)(cheng)鋯莫來石(shi)(shi)(shi)(shi);高鋁(lv)礬土與(yu)菱鎂(mei)(mei)礦組成(cheng)(cheng)鋁(lv)鎂(mei)(mei)尖(jian)晶石(shi)(shi)(shi)(shi);菱鎂(mei)(mei)礦與(yu)白云石(shi)(shi)(shi)(shi)組成(cheng)(cheng)鎂(mei)(mei)鈣(gai)砂;用高鈣(gai)菱鎂(mei)(mei)礦與(yu)鐵精礦配(pei)料(liao)(liao)組成(cheng)(cheng)鎂(mei)(mei)鐵鈣(gai)砂;菱鎂(mei)(mei)礦與(yu)鋯英石(shi)(shi)(shi)(shi)組成(cheng)(cheng)鎂(mei)(mei)鋯砂;葉蠟石(shi)(shi)(shi)(shi)與(yu)滑石(shi)(shi)(shi)(shi)組成(cheng)(cheng)堇(jin)青石(shi)(shi)(shi)(shi);用菱鎂(mei)(mei)礦與(yu)二級高鋁(lv)礬土熟(shu)料(liao)(liao)配(pei)料(liao)(liao),焦炭作(zuo)為還原(yuan)劑,通過碳熱(re)還原(yuan)氮化(hua)組成(cheng)(cheng)Sialon—尖(jian)晶石(shi)(shi)(shi)(shi)復(fu)相(xiang)資料(liao)(liao);藍晶石(shi)(shi)(shi)(shi)與(yu)石(shi)(shi)(shi)(shi)墨配(pei)料(liao)(liao),原(yuan)位組成(cheng)(cheng)AlN—SiC復(fu)相(xiang)資料(liao)(liao)等。

所謂組(zu)成耐(nai)火(huo)(huo)質料(liao),就是(shi)將兩種(zhong)或(huo)兩種(zhong)以上的天然(ran)礦藏(zang)(zang)質料(liao)或(huo)化(hua)工質料(liao)或(huo)廢棄(qi)物(wu),通過配料(liao)、粉碎,磨細,混合,成型,煅燒或(huo)電熔等工藝進程,合成鎂鐵鈣砂制取必定化(hua)學礦藏(zang)(zang)組(zu)成和物(wu)理性能的耐(nai)火(huo)(huo)質料(liao)。組(zu)成耐(nai)火(huo)(huo)質料(liao)的品(pin)種(zhong)繁復,組(zu)成辦法(fa)多(duo)種(zhong)多(duo)樣,大(da)體簡(jian)略(lve)介(jie)紹:

 純(chun)化(hua)工(gong)(gong)質料(liao)(liao)之間組(zu)(zu)成(cheng)耐(nai)火質料(liao)(liao),如用工(gong)(gong)業氧化(hua)鋁(lv)與鈦白(bai)粉(fen)組(zu)(zu)成(cheng)鈦酸(suan)鋁(lv);鋁(lv)粉(fen)與氮氣化(hua)合組(zu)(zu)成(cheng)AIN(氮化(hua)鋁(lv));工(gong)(gong)業氧化(hua)鋁(lv)與高純(chun)超細(xi)的氮化(hua)鋁(lv)粉(fen)組(zu)(zu)成(cheng)Alon(阿(a)隆);用輕(qing)質碳酸(suan)鈣與工(gong)(gong)業氧化(hua)鋁(lv),按CA6的CaO與Al?O?的化(hua)學計量比例配(pei)料(liao)(liao),組(zu)(zu)成(cheng)六(liu)鋁(lv)酸(suan)鈣;用鈦白(bai)粉(fen)和金屬鋁(lv)粉(fen)在流動氨氣效果下(xia),原(yuan)位生成(cheng)Al?O?-TiN復相(xiang)資料(liao)(liao)等(deng)。

所謂組成(cheng)耐火質(zhi)料,就是將兩(liang)(liang)種或(huo)兩(liang)(liang)種以(yi)上的(de)天然礦藏(zang)質(zhi)料或(huo)化工質(zhi)料或(huo)廢棄物,通過配料、粉碎,磨細(xi),混合(he),成(cheng)型(xing),煅燒或(huo)電(dian)熔等工藝進(jin)程,合(he)成(cheng)鎂鐵鈣砂制取必(bi)定(ding)化學礦藏(zang)組成(cheng)和物理性能(neng)的(de)耐火質(zhi)料。
