Abstract

Expanded perlite products having controlled particle size distribution, methods of producing the expanded perlite products, and methods of use there of are provided. The expanded perlite product has, for example, a low ratio of standard deviation of particle size distribution to median particle size (fo r example, less than 0.63) and low median particle size (for example, less tha n 50 microns). The expanded perlite product may be used in a variety of applications including filter applications.
