Abstract

Powder compacts of synthetic mica (fluorphlogopite) encapsulated in a borosilicate glass tube were isostatically hot-pressed in a Roy-Tuttle-type pressure vessel. Synthetic mica was sintered to a density of 2.60 g /cm3 (91.2% of theoretical density) without additives under 98 MPa of water at 800° C for 45 min.
