China Floating Refractory Hollow High Quality Microspheres Fine Cenosphere, Find details about China Cenospheres, Cenospheres Price from Floating Refractory Hollow High Quality Microspheres Fine Cenosphere
Product Description:
Cenosphere, sometimes called microsphere, is a light weight, inert, hollow sphere made largely
of silica and alumina and filled with air or inert gas., typically produced as a byproduct of coal
combustion at thermal power plants. The color varies from gray to almost white and their den
sity is about 0.6-0.9 g/cm³, all these property give it a widely application for insulation,refract
ory,oil drilling,coating,construction use.
Cenosphere Specification:
SiO2 | 50-55% |
Al2O3 | 28-33% |
Fe2O3 | 2-4% |
SO2 | 0.1-0,2% |
CaO | 0.2-0.4% |

Product Applications:
1), Chemicals/Coating/Painting --- Provide measuring tool in biology and drug research, besides added to paints
and epoxies to modify viscosity and buoyancy ;
2), Plastics --- Used to decrease material density (glass and polymer);
3), Ceramics --- Used to create porous ceramics used for filters;
4), Cosmetics --- Used to hide wrinkles and give color;
5), Electronic paper --- Dual Functional microspheres used in Gyricon electronic paper
6), Insulation --- expandable polymer microspheres are used for thermal insulation and sound dampening.
7), Retroreflective --- added on top of paint used on roads and signs to increase night visibility of road
stripes and signs;
