ABSTRACT:
Processes and apparatus for the production of hollow microspheres by thermal expansion of glass particles including the thermal treatment of extremely small glass particles whose dimensions are less than 50 micrometers and, preferably, less than 35 micrometers or even 20 micrometers, which include a fluidizing agent. This technique makes possible the production of extremely small glass microspheres under satisfactory yield conditions. Also, the hollow microsphere products produced by these processes and apparatus.
