Cenosphere

Introduction

Cenospheres are hollow silicate micro-spheres extracted from the fly ash generated in coal-fired power plants. They are in white or light gray color and have a particle size from 20 to 500 microns 20-500 mesh.

Applications

Due to their unique combination of low specific gravity, spherical shape, controlled size, high compression , good thermal and acoustical insulation property, many high value applications can be made&#65306
