  • Patent number: 11478850
    Abstract: 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.
