The sintering of a non-spherical aluminosilicate glass powder was investigated using a heating microscope. The samples showed shrinkage anisotropy. The densification rate shows a stronger dependence on density than the prediction of Scherer's theory. The ratio of the creep rate due to anisotropic shrinkage to the densification rate shows no significant variation with density but it depends on the degree of shrinkage anisotropy.
