A method is provided for synthesizing beads using starting ceramic, metal, or mineral powders. Typical size of these round beads can range from about 0.1 mm to about 10 mm based on the processing variables. In the method, a slip is obtained which contains a metal, ceramic, and/or mineral powder dispersed in a solvent and an organic binder, such as a grain flour. Droplets of the slip are contacted with heated oil for a sufficient time to form beads. The beads are separated from the oil and dried to remove entrained water. The beads are fired at a temperature sufficient to produce beads possessing desired physical or chemical characteristics. The beads have useful biomedical applications as bone filler materials for bone fixation and bone growth. The beads may be coated with chemical catalyst agents and function as catalyst supports in chemical processes.
