1. Introduction:
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 20 to 500 microns.
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.
2. Cenosphere Advantage:
1) Excellent fluidity
In hollow micro-spherical shape and with size from 20 to 500micron, cenospheres can improve Fluidity of filler and make it easier to be used.
2) Heat-insulating and sound-insulating
Lower conductivity makes it widely used in producing heat-insulation and sound-insulation materials and Equipments.
3)
Chemical stability
Chemical features (alumina silicate) of cenospheres can maintain their integrity while they are utilized in Water, organic chemicals
Acid,
Alkali and other solvents.
4) High refractoriness
Cenospheres have a high refractoriness. It can still keep a good stability while being heated over 1000C.
5) High Strength
Cenospheres are three to ten times stronger than most man-made hollow glass spheres. Unlike glass spheres, Cenospheres can produce a higher compressive strength due to a stronger outer shell.
6) Lower cost
Cenospheres have an advantage in cost compared with other fillers and man-aade micro spheres.
3. Applications:
Widely used in building material, plastics, oil field, paint&coating, automobile, air craft etc.
