To investigate the possibility of developing a humidity self-control material, mesoporous-powder prepared by selective leaching method was pressed and fired with adding organic binders. A comparison was carried out with a material fired with clay binder. The specific surface area, total pore volume, pore size distribution, and water vapor adsorption of the fired bodies were measured for samples prepared at various firing temperatures, to evaluate the humidity controlling properties. The amount of water vapor adsorbed by the fired bodies decreased with increasing the firing temperature of the bodies. The amount of water adsorption on the body fired at 900℃ (GK33-900) at a relative humidity between 30 and 60%, and between 60 and 90% was, however, similar to that of the original powder. It was found that the dry pressing process with organic binders was more suitable than that with clay binders and it was possible to manufacture the fired body preserving the humidity self-control property.
