Provided is a method of imparting antibacterial and deodorant functions by reacting iodic acid, and a material that is given antibacterial and deodorant functions. The method of imparting antibacterial and deodorant function is as follows. Reacting iodate to a material that includes elements capable of producing iodate insoluble in water and non-toxic to a living body to form iodic acid of such elements on the surface of the material, thereby the iodate is made to be supported so that antibacterial and deodorant is possible without elution of said iodate to the outside.

A method to produce metallic beryllium spheres with high sphericity in a large quantity efficiently at a low cost is provided herein. The method of continuously producing metal beryllium spheres comprises the steps of: collecting granulated beryllium spheres produced by charging beryllium powder into a rotary kiln; classifying the collected beryllium spheres by particle size with an automatic sieve; and crushing particles of beryllium spheres of non-target diameters and mixing them with the raw material beryllium powder for reuse. The rotary kiln has a core tube the inner surface of which is coated with beryllium oxide by sintering the slurry coating of beryllium hydroxide applied after alkaline silica treatment.
