AN IMPROVED ENVIRONMENT FRIENDLY, ENERGY SAVING MICROWAVE PROCESS FOR FAST SINTERING OF SHAPED PORCELAIN COMPONENTS IN AIR

摘要

: This invention relates to an improved environ-friendly,energy saving microwave process for fast sintering of shaped porcelain components in air from quartz based raw materials consisting of feldspar,washed clay,raw clay, quartz, pyrophyllite and felcite comprising:firing shaped component in a microwave furnace using a suitable casket and susceptor arrangement in air at peak sintering temperature of 1200°C to 1260° C with soaking period of 30 minutes; maintaining heating cycle from 6 to 10 hour during sintering; resulting densified porcelain product with reduced porosity, higher bending strength and electrical properties through phase formation comprising of Quartz,Mullite and amorphous.
