Cenosphere
Introduction of Cenosphere
Global Manufacturer (Processor) & Supplier | Excellent Quality | Bulk Export Orders
A Cenosphere is a lightweight, inert hollow ceramic sphere (Expanded Mineral Materials), made to a great extent of silica and alumina and filled with air or inactive gas, commonly processed as a by-result of coal burning at fired power plants that are extracted from the fly ash.
Cenosphere fluctuates from light black colour to practically white shade and their specific gravity extends in the middle of 0.4–0.8 g/cm³, which offers them extraordinary lightness.
Cenosphere are used in various industries due to their unique combination of spherical shape, high compression, low specific gravity, good thermal and acoustical insulation properties and inertness to acids and alkalis.
We are exporters and suppliers of Cenosphere to industries worldwide looking for fillers to reduce cost and improve product quality.

Health and Safety Information
Cenosphere series is an inert material similar to talc, etc. The material may be prone to dusting in use. During processing or otherwise generating dust may create a respiratory hazard. In high dust areas the use of goggles and approved dust respirator is recommended. A Material Safety Data Sheet (MSDS) will be supplied on request.
