To investigate the possibility of developing a humidity self-control material, the shaping and firing of mesoporous-powder (mainly y-alumina phase), made by selective leaching method, were investigated adding 10 mass% of coal kaolin. The specific surface area, total pore volume, pore size distribution and water vapor adsorption of fired bodies were measured for samples prepared with various calcination and firing temperatures to evaluate the humidity controlling properties. The amount of water vapor adsorbed on the fired bodies decreased compared with that of the powder. However, this decrease was larger at relative humidities between 0 and 60% than that between 60 and 90%, namely, an increase in water vapor adsorption at around the relative humidity of 50-70% was found. The present mesoporous y-alumina fired body is thought to be a promising candidate as humidity self-control material.
