Additional Description

Properties of Cenosphere

Cenospheres are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion

during the generation of electric power. Small and hollow, microspheres are used as fillers or functional

extenders in the manufacture of plastics, paints, resins; light weight aggregates for cement, ceramics

and other construction products. Because Cenospheres often replace mined materials, they can significantly

lower production costs. Simultaneously, cenosphere can benefit finished product properties by increasing

durability and better sound proofing. Too, as material recycled from fly ash, cenosphere are environmentally

friendly and help to preserve natural virgin fillers.

As a portion of the fly ash generated in coal combustion, cenosphere are recycled from the waste stream.

They are made up of inert silica, iron and alumina. Cenospheres have a size range from 1 to 300 microns

with an average compressive strength of 3000+ psi.. Colors range from white to dark gray. They are also

referred to as microspheres, hollow spheres, hollow ceramic microspheres, micro balloons, or glass beads.

The spherical shape of cenosphere improves flow ability in most applications and provides a more even

distribution of the filler material. The natural properties of cenosphere make it possible to use them either

in dry or wet slurry form. Cenospheres are easy to handle and provide a low surface area-to-volume ratio.

Due to their inert properties, they are not affected by solvents, water, acids, or alkalis. Cenospheres are 75%

lighter than other minerals currently used as a filler or extender.


 

The mainly advantages of using cenosphere are :

Reduced Raw Materials Cost

Improved Flow ability

Reduced Resin Demand

Improved Insulation Values

Reduced End Product Weight

Resistant to Resin Absorption
