Application of oil shale mining by-products as raw materials in the determination of the vitrification curve of red porcelain stoneware tiles by dilatometric method

Sintering behaviour of a clay containing pyrophyllite, sericite and kaolinite as ceramic raw materials: Looking for the optimum firing conditions

“…The variation of linear shrinkage and determination of the vitrification curve of stoneware tiles (red porcelain) have been studied by Melnick et al [13]. They used a dilatometric method with a dwell time of 1 h at the final temperature (1100 • C).…”
