<p>A humidity-controlling tile can be produced by mixing 70 wt.% of porous alumina particles having specific pores (having pore diameters of about 3 to 8 nm and a pore volume of about 0.4 cc/g) as aggregate with 20 wt.% of glass frit as binder and 10 wt.% of clay as plastic material with the water content controlled suitably, press-molding the slurry thus obtained into a tile-shaped product, and firing the product at a temperature (about 850 °C) lower than the melting temperature of alumina but higher than that of the binder (glass frit) to bind the porous alumina particles with molten glass frit. The tile has a structure wherein porous alumina particles having the above specific pores and being adjacent to each other are bonded to each other with glass frit, thus being useful as a humidity-controlling functional material having a high humidity-controlling performance.</p> |
