Cenospheres are unique free flowing powders composed of hard shelled, hollow, minute spheres. A small proportion of the pulverised fuel ash (PFA) produced from the combustion of coal in power stations is formed as cenospheres.

The main characteristics are:

•Hollow spheres with spherical morphology.

•Particle sizes ranging from 5 to 500μm in size.

•Ultra low density.

•Low thermal conductivity.

•High particle strength.

•Resistant to acids.

•Low water absorption

The main application in that of an inert filler. With a density lower than water (typically 0.6 – 0.8) cenospheres provide up to four times the bulking capacity of normal weight fillers.

Benefits:

A lower density compared to conventional fillers providing opportunities for weight reduction

Improved flow characteristics attributable to the spherical particle shape

Reduced shrinkage

Low oil (resin) absorption

Good chemical resistance

Increased hardness, scratch and abrasion resistance

Good thermal characteristics (lower specific heat capacity)

High compressive strength
