【Abstract】 To improve the sinterability of cordierite-based MgO-Al 2O 3-SiO 2 system glass, leadsilicate glass was adopted as a sintering aid. The effect of various leadsilicate glass content on the microstructure and density of sintered glass ceramics was investigated.It was found out that leadsilicate glass can promote the densification of cordierite glass powders, and sintered sample’s density increased with increasing of the leadsilicate glass content.更多还原
