摘要： Process for producing microspheres comprises immersing a lower portion of a generally vertical, sol-gel feed tube having a lower microsphere formation needle in an alcohol drying column, feeding sol-gel at a predetermined rate into the upper end of the feed tube, and vibrating the feed tube in a generally horizontal direction at a predetermined amplitude and frequency to produce microspheres from the formation needle of a uniform and predetermined size. An electromagnetic transducer drive for vibrating the feed tube is used in one illustrative embodiment of apparatus for practicing the invention, and an electric motor offset drive is used in another illustrative embodiment of such apparatus. A feed tube having multiple microsphere formation needles at its lower end can be used for producing microspheres in quantity.
