of ceramic were studied by testing the surface tension and contact angle of water, latex stability inside of ceramic product. Results that the ceramic doped enamel slurry with rare earth phosphate composite materials can reduce obviously the surface tension and contact angle of water, and make latex more stable, and so the ceramics possess excellent cleanout oil-dirty property. Key words:ceramics......
