Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

Additional information

The composition, physical and chemical properties of cenospheres, fly ash, alumo silicate are variable. This arises principally from the raw materials and from the combustion and abatement technologies used. The process of burning coal in thermal power plants produces fly ash and the cenospheres. Cenospheres are lightweight, inert, hollow spheres filled with inert air or gas, typically produced as a by-product of this coal combustion. Based on the chemical nature of cenospheres, neither photo- or chemical degradation, nor biodegradation (due the absence of carbon atoms within the molecule) is expected. Therefore, degradation is considered negligible.
