Abstract

Lithium metasilicate pellets fabricated by cold compaction and sintering have been characterized in order to see how fabrication parameters control their density, structure and porosity. Milling conditions, drying technique, calcination and sintering temperatures, precompaction pressure as well as the kind of raw materials and stoichiometry are some of the factors investigated. A proper combination of the fabrication parameters allows to control the final density from 60 to 96% T.D. The porosity distribution depends mostly on the density of the sintered products: up to 77% T.D. all pores are open and above 89-90% T.D. usually closed. Nevertheless, it is possible to fabricate 91-96% T.D. pellets with a very extended open porosity by recrystallization above 925°C.
