Preparation of Humidity Control Ceramics from Selectively Leached Kaolin

Abstract:

The humidity control ceramics were prepared by selective leaching and sintering of Suzhou kaolin clay. Effects of sintering temperature and solid/liquid ratio of selecting leaching of the kaolin clay on the humidity controlling properties of ceramics were analyzed. It was found that the ceramic had the best properties when the kaolin clay was sintered at 1000oC for 2 hours and leached with the solid/liquid ratio being 1:50. Water vapor adsorption isotherms of the ceramic possessed a sharp increase in the relative humidity between 45 and 85%.
