【摘要】 选取了三种不同组成的优良陶瓷辊棒对其化学-矿物组成和显微结构特征进行了研究,发现以莫来石为基质结合的刚玉复相材料,具有较高耐高温性能和抗热震性能。刚玉莫来石复相中分别引入适量的MgO,K2O,ZrO2可以更好的改善陶瓷辊棒的显微结构及性能。更多还原

【Abstract】 This paper studies the chemical- mineral composition and microstructure of three kinds of well- selected fine ceramics roll bar and finds that the fused alumina composition inlays in mullite substrate has high performance in resistance to high temperature and thermal shock. If proper amount of MgO,K2O,ZrO2 are added to the composition of mullite and fused alumina, the microstructure of ceramics roll bar will be improved.更多还原
