堇青石陶瓷烧结工艺及机理研究
Sintering Process and Mechanism of Cordierite Ceramic
【摘要】 本文利用DSC、XRD技术,研究了MgO、AlO3和SiO2反应烧结制备堇青石陶瓷的机理。结果表明MgO和Al2O3在1155℃反应合成镁铝尖晶石(MgAl2O4),进而在1317℃长时间保温与SiO2反应生成堇青石。
【Abstract】 Cordierile ceramic was prepared by reaction sintering of MgO, Al2O3 and SiO2, and the corresponding sintering mechanism was investigated using DSC and XRD. It is shown that spinelle ( MgAl2O4 ) was firstly synthesized by reaction of MgO and Al2O3 at 1155° C, further, which reacted with SiO2 under long time sintering at 1317℃and formed cordierite ceramic.
