Cenosphere is a lightweight, inert, hollow sphere comprising of largely of silica and alumina and filled with air and / or gases. Cenospheres are a naturally occurring by-product of the burning process at coal-fired power plants, and they have most of the same properties as manufactured hollow-sphere products.

Chemical properties:
1) SiO2: 55% - 65% 
2) Al2O3: 25% - 30% 
3) Fe2O3: 1% - 5% 

Physical properties:
1) Size: 0-350 microns 
2) pH in water: 6.0 - 8.0 
3) Bulk density: 23 - 28lbs/cu. ft. 
4) Specific gravity 0.6 - 0.8 
5) Softening point above 1,800 degrees F 
6) Shape spherical 
7) Color: grey, light grey, Packing: 600kg in one Jumbo bag, 1.25MT<20 bags> in 1x20'fcl
