Introduction:
1. Cenospheres are hollow
silicate micro-spheres extracted from the fly ash generated in
coal-fired power plants. They are in white or light gray color and
have a particle size from *0 to **0 microns.
2. They have excellent
fluidity as well as sound, electric and heat insulation,
cenospheres are a filler used to replace minerals and resins where
the benefits may be as diverse as weight reduction, improved
thermal insulation, reduced shrinkage, improved fire resistance or
simply easier application.
Applications:
Cenosphere applications offer
many benefits over mined materials, primarily cost and weight
reduction. Of their many uses, microspheresare used as light weight
aggregate in oil well cements, sound proofing, thermal insulation,
interior and exterior paints, injection molding ofplastics,
automotive brake linings, and are even used by NASA in the nose of
the Space Shuttle. Desirable properties include: Controllable
density for buoyancy, improved flow, excellent thermal insulation,
light weight, and high strength. Environmentally friendly and **0%
they aid not only the coal fired power plants control their
pollution, but make their use earth conscious.
