Isothermal Sintering of Spheroidized Cordierite‐Type Glass Powders
Abstract
Jagged (ball–milled) glass particles were spheroidized and pressed into compacts which were isothermally sintered in air. Both jagged‐ and spheroidized‐particle compacts showed about the same 0.7 anisotropy of the ratio of axial to diametral shrinkage, but spheroidizing reduced the shrinkage rate. Thus, shrinkage anisotropy is not a simple particle shape effect; it may relate to differences in the axial and radial distributions of particle sizes present in these compacts.
