摘要
采用原位合成技术合成莫来石-钛酸铝复相材料(ATM),并以复相材料和烧结莫来石(M60)为主要原料制备莫来石-钛酸铝窑具,借助于XRD、SEM和热态模拟试验等手段研究了烧成温度、复相材料添加量对莫来石-钛酸铝高温窑具性能和显微结构的影响。结果表明:合成的莫来石-钛酸铝复相材料适于制备高温窑具;在1600℃烧成的窑具试样具有较高的高温抗折强度和良好的抗热震性;合成复相材料的添加量为45%时可获得综合性能好的窑具材料;热态模拟试验表明研制的莫来石-钛酸铝高温窑具适合在低于1400℃,承重小于8kg的条件下使用。
Mullite -aluminum titanate composite （ATM） was prepared by in-situ synthesis. Mullite -aluminum titanate kiln furniture was prepared using ATM and sintered mullite （M60） as main starting materials. Effects of firing temperature and ATM content on properties and microstructure of mullite -aluminium titanate high temperature kiln furniture were investigated by means of XRD,SEM and hot simulation test. The results showed that. ATM was suitable for preparing high temperature kiln furniture. The kiln furniture specimens fired at 1600℃ had higher high temperature bending strength and excellent thermal shock resistance. The prepared kiln furniture had good comprehensive properties when ATM content was 45%. Hot simulation test showed that the prepared mullite -aluminium titanate high temperature kiln furniture was suitable used below 1 400 ℃ and lower than 8 kg load bearing.
