China Aluminum Silicate Floating Beads Fly Ash Cenosphere Special for Oil Field Cementing, Find details about China Cenospheres, Cenospheres Price from Aluminum Silicate Floating Beads Fly Ash Cenosphere Special for Oil Field Cementing
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;
