Properties of Porcelain Supported by Addition of Beryllium Oxide

Abstract

Due to its specific characteristic of porcelain, specific recipes have been prepared. The basic materials and quantities were selected carefully because it possesses particular specifications. In this work, porcelain containing 32 wt.% feldspar, 24 wt.% quartz and 44 wt.% clay was synthesized. Different  melting temperature (1300°C, 1375 °C and 1450°C)  and  insertion of beryllium oxide (BeO) (1, 3, 5 and 7 wt.%) were done. The effects of temperatures and beryllium oxide content on mechanical, electrical and structural properties on the prepared porcelain were studied. The increasing of heat treatment for the basic porcelain leads to an enhancement in bulk density and compressive strength. Basic porcelain which suffering lower annealing temperature (1300°C) introduces higher dielectric constant values in contrast with that suffering higher temperature (1450°C).  The addition of BeO to the basic porcelain leads to decrease the bulk density and compressive strength. Porcelain with lower annealing temperature introduces higher έ values in contrast with higher temperature.
