鎂鈣砂

 可用(yong)天然礦(kuang)藏(zang)質料本身之間的檔(dang)次不同配(pei)料組成，如莫來石(shi)(shi)，也可不同天然礦(kuang)藏(zang)質料配(pei)料組成，如用(yong)高鋁礬(fan)土與(yu)(yu)鋯英石(shi)(shi)精(jing)礦(kuang)組成鋯莫來石(shi)(shi);高鋁礬(fan)土與(yu)(yu)菱鎂(mei)礦(kuang)組成鋁鎂(mei)尖晶(jing)石(shi)(shi);菱鎂(mei)礦(kuang)與(yu)(yu)白云石(shi)(shi)組成鎂(mei)鈣(gai)砂;用(yong)高鈣(gai)菱鎂(mei)礦(kuang)與(yu)(yu)鐵精(jing)礦(kuang)配(pei)料組成鎂(mei)鐵鈣(gai)砂;菱鎂(mei)礦(kuang)與(yu)(yu)鋯英石(shi)(shi)組成鎂(mei)鋯砂;葉(xie)蠟石(shi)(shi)與(yu)(yu)滑石(shi)(shi)組成堇青石(shi)(shi);用(yong)菱鎂(mei)礦(kuang)與(yu)(yu)二級高鋁礬(fan)土熟料配(pei)料，焦炭作為還原(yuan)劑，通(tong)過(guo)碳熱還原(yuan)氮化組成Sialon—尖晶(jing)石(shi)(shi)復相(xiang)資(zi)料;藍(lan)晶(jing)石(shi)(shi)與(yu)(yu)石(shi)(shi)墨(mo)配(pei)料，原(yuan)位組成AlN—SiC復相(xiang)資(zi)料等。

所謂組(zu)成耐(nai)火質(zhi)料，就是將(jiang)兩(liang)種(zhong)或兩(liang)種(zhong)以(yi)上的(de)天然礦藏質(zhi)料或化(hua)工(gong)質(zhi)料或廢(fei)棄物，通過配(pei)料、粉碎，磨細，混合，成型(xing)，煅燒或電熔(rong)等(deng)工(gong)藝(yi)進程，合成鎂鐵(tie)鈣砂(sha)制(zhi)取(qu)必定化(hua)學(xue)礦藏組(zu)成和物理性能的(de)耐(nai)火質(zhi)料。組(zu)成耐(nai)火質(zhi)料的(de)品種(zhong)繁復，組(zu)成辦法多種(zhong)多樣，大體簡略介紹：

 純化(hua)工(gong)(gong)質料之間組成(cheng)(cheng)(cheng)(cheng)耐(nai)火質料，如用工(gong)(gong)業(ye)氧(yang)(yang)化(hua)鋁(lv)與鈦白粉(fen)組成(cheng)(cheng)(cheng)(cheng)鈦酸鋁(lv);鋁(lv)粉(fen)與氮(dan)氣化(hua)合組成(cheng)(cheng)(cheng)(cheng)AIN(氮(dan)化(hua)鋁(lv));工(gong)(gong)業(ye)氧(yang)(yang)化(hua)鋁(lv)與高純超細的氮(dan)化(hua)鋁(lv)粉(fen)組成(cheng)(cheng)(cheng)(cheng)Alon(阿隆);用輕質碳酸鈣(gai)與工(gong)(gong)業(ye)氧(yang)(yang)化(hua)鋁(lv)，按CA6的CaO與Al?O?的化(hua)學(xue)計量比例(li)配(pei)料，組成(cheng)(cheng)(cheng)(cheng)六鋁(lv)酸鈣(gai);用鈦白粉(fen)和金屬鋁(lv)粉(fen)在流動氨(an)氣效果下，原(yuan)位生成(cheng)(cheng)(cheng)(cheng)Al?O?-TiN復相資料等。

所(suo)謂組成(cheng)(cheng)耐火(huo)質(zhi)料，就是將兩(liang)種(zhong)或兩(liang)種(zhong)以上的(de)天然礦(kuang)藏質(zhi)料或化(hua)(hua)工質(zhi)料或廢棄(qi)物，通過(guo)配料、粉碎，磨細，混(hun)合，成(cheng)(cheng)型，煅(duan)燒或電熔等(deng)工藝進程，合成(cheng)(cheng)鎂鐵鈣砂制取(qu)必定(ding)化(hua)(hua)學礦(kuang)藏組成(cheng)(cheng)和物理性能的(de)耐火(huo)質(zhi)料。
