School of Materials Science and Engineering, Shaanxi University of Science and Technology, Xi’an 710021; 2. Shanghai Institute of Ceramics, Chinese Academy of Sciences, Shanghai 200050, China) Abstract: The separative-phase characteristics for bination of droplets with primary colors of the basic glaze of ceramic glazes were investigated by the separative-phase colored glaze method in a R2O–RO–Al2O3–SiO2–P2O5(R2O: Na2O, K2O and L2O and RO: CaO, MgO etc.) system with the addition of different contents of Ca3 (PO3)2, talc, quartz and calcite. The effects of the physical optics principle of separative-phase coloring, position and sintering temperature for glaze coloring on the coloring mechanism were studied with the quartering batching method, scanning ele
