Terracotta clay is a natural resource that has the potential as raw material in ceramic field. This study investigates effects of color glaze using terracotta powder an alternative substance for colorants formulation. proportionately added to formulations determine at temperatures ranging from 1140 °C 1200 °C. The content bounded with potash feldspar, silica, zinc oxide, and calcium carbonate. ...

OBJECTIVE To investigate the two-body wear performance of monolithic dental ceramics with different surface treatments. METHOD AND MATERIALS Standardized specimens (n = 8/ series) were fabricated from three monolithic dental ceramics (experimental translucent zirconia, experimental shaded zirconia, lithium disilicate). Four groups of each material were defined according to clinically relevant...

This study provides a baseline from which changes in the chemistry of the atmosphere over Antarctica can be monitored under expected warming scenarios and continued intensification of industrial activities in the Southern Hemisphere. It is the first study to measure more than 25 chemical constituents in the surface snow and firn across extensive regions of Antarctica. We present major ion, trac...
