The influence of incorporation of ZnO-containing glazes on the properties of hard porcelains


New ZnO-containing glazes were developed, characterized and incorporated (5-8 wt.%) in conventional hard porcelain formulation for producing tableware porcelains. The experimental results showed that glaze additives enhancement the densification of porcelains. Maturing temperature range was widened due to the dissolution of quartz crystals. The modified porcelains featured better mechanical properties and whiteness and lower shrinkage than conventional hard porcelains. Good matching of thermal properties between porcelain body and glaze resulted in successful glazing. (c) 2006 Elsevier Ltd. All rights reserved.
