<p>A method for producing a porous fired material having a silver colloid being carried thereon, which comprises the steps of kneading a powdery charcoal with clay, firing the kneaded product, and pulverizing the fired product into particles having a diameter of 1 to 5 µm, spraying a distilled water having 100 to 200 ppm of a silver colloid having a size of 1 to 6 nm dispersed therein to the pulverized porous fired product, and agitating them, and then drying the resultant product at 60 to 120°C. The porous fired material having a silver colloid being suitably carried thereon may be produced by the above method.</p> |
