Cenospheres

Cenospheres are hollow silicate micro-sphere extracted from 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 and heat insulation.

Advantage:

*Excellent fluidity

In hollow micro-spherical shape and with size from 20-500 micron, cenosheres can improve fluidity of filler and make it easer to be used.

*Heat-insulation and sound-insulation

Lower conductivity makes it widely used in producing heat-insulation and sound-insulation products.

*Chemical stability

Chemical feature (alumina silicate) of cenospheres can maintain their integrity while they are utilized in water, organic chemicals, acid, alkali and other solvents.

*High refractoriness

Cenosphers have a high refractoriness. It can keep a good stability while being heated over 1000℃.

*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.

*Lower cost

Cenospheres have an advantage in cost compared with other fillers and man-made microspheres.

Applications:

Widely used in building material, plastic, oil field, paint&coating, automobile, air craft etc.

Packing:

In 25KGS paper bags or in 1000KGS super bags.
