所(suo)謂組(zu)成(cheng)耐火質料,就是將兩種(zhong)或(huo)兩種(zhong)以上(shang)的天(tian)然礦藏質料或(huo)化(hua)工質料或(huo)廢(fei)棄物,通過配料、粉碎,磨細(xi),混合,成(cheng)型(xing),煅燒或(huo)電熔等工藝(yi)進程(cheng),合成(cheng)鎂鐵鈣砂制(zhi)取必(bi)定化(hua)學礦藏組(zu)成(cheng)和物理(li)性能的耐火質料。組(zu)成(cheng)耐火質料的品種(zhong)繁復,組(zu)成(cheng)辦法(fa)多種(zhong)多樣,大(da)體簡略介紹:
純化(hua)(hua)工(gong)質料(liao)(liao)(liao)之(zhi)間組(zu)成(cheng)耐火質料(liao)(liao)(liao),如用(yong)工(gong)業(ye)(ye)氧化(hua)(hua)鋁與(yu)鈦白粉(fen)組(zu)成(cheng)鈦酸鋁;鋁粉(fen)與(yu)氮(dan)氣化(hua)(hua)合組(zu)成(cheng)AIN(氮(dan)化(hua)(hua)鋁);工(gong)業(ye)(ye)氧化(hua)(hua)鋁與(yu)高純超細(xi)的氮(dan)化(hua)(hua)鋁粉(fen)組(zu)成(cheng)Alon(阿隆(long));用(yong)輕質碳酸鈣與(yu)工(gong)業(ye)(ye)氧化(hua)(hua)鋁,按(an)CA6的CaO與(yu)Al?O?的化(hua)(hua)學計量比例配(pei)料(liao)(liao)(liao),組(zu)成(cheng)六鋁酸鈣;用(yong)鈦白粉(fen)和金屬鋁粉(fen)在流動氨氣效果下,原(yuan)位生(sheng)成(cheng)Al?O?-TiN復相資料(liao)(liao)(liao)等(deng)。
所謂組成(cheng)耐火質(zhi)料(liao),就(jiu)是將兩種(zhong)(zhong)或兩種(zhong)(zhong)以上的(de)(de)天(tian)然(ran)礦藏(zang)質(zhi)料(liao)或化工質(zhi)料(liao)或廢棄物,通過配料(liao)、粉碎,磨細,混合,成(cheng)型,煅(duan)燒(shao)或電(dian)熔等工藝(yi)進(jin)程,合成(cheng)鎂(mei)鐵(tie)鈣砂制取必定化學礦藏(zang)組成(cheng)和物理性能的(de)(de)耐火質(zhi)料(liao)。
