Abstract

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 μm in average diameter were successfully produced. This is the first work producing Shirasu balloons using a high-velocity fluidized bed reactor.
