A reactor consisting of a high-velocity fluidized bed reactor with circulating ceramic particles as a thermal medium is proposed to produce hollow inorganic microspheres (so-called Shirasu balloons) from a volcanic glass, Shirasu. Using the reactor, Shirasu balloon production was investigated. Shirasu balloons of 25 <I>μ</I>m in average diameter were successfully produced. This is the first work producing Shirasu balloons using a high-velocity fluidized bed reactor.
