Abstract
Hollow inorganic microparticles were produced continuously from a volcanic glass (shinju-gan or per-lite) using an entrained bed reactor. The microparticles are called expanded perlite. The raw material was a sieved fraction (104 μm in volume average diameter) of crushed perlite, which is from China. The effects of temperature and residence time on expanded perlite yield were investigated.
