High-Pressure Hot Isostatic Pressing of Synthetic Mica

Abstract

Powder compacts of synthetic mica CfZuorphlogopite) encapsulated in a borosilicate glass tube were isostatically hot-pressed using high-pressure-hightemperature hot isostatic pressing equipment with Ar gas and a M o heater. Synthetic mica was isostatically hot-pressed, while retaining the composition and structure of the starting material, to 96.8% of theoretical density without additives at 500 MPa and 700 O? for 3 11.
