Cenosphere is a lightweight, inert, hollow sphere filled with inert air or gas, typically produced as a byproduct of coal combustion at thermal power plants.
The color of cenospheres varies from gray to almost white and their density is about 0.4-0.8 g/cm3, which gives them a great buoyancy.
Flows like a liquid, with the appearance of a powder. Provides lightweight bulk to a varied and expansive range of compounds. Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
| Chemical Analysis % | Physical Data | ||
| SiO2 | 54-60 | Shape | Powder |
| Al2O3 | 35-42 | Bulk Density | 0.3-0.45g/cm3 |
| Fe2O3 | 1.2-2.0 | Specific Gravity | 0.8-1.0g/cm3 |
| CaO | 1-1.5 | Heat Conductivity | 0.1-0.2W/m2K |
| MgO | 0.3-0.4 | Flotage Rate | 97% |
1.Cenospheres are now used as fillers in cement to produce low-density concrete.
2.Its spherical shape and structure features improve the fluidity of materials and distribution in a form when filling volume.
3.It is excellent insulating material for buildings, constructions, and pipelines.
4.Some manufacturers have begun filling metals and polymers with cenospheres to make lightweight composite materials with higher strength than other types of foam materials.
5.Such composite materials are called syntactic foam. Aluminum-based syntactic foams are finding applications in the automotive sector. Silver-coated cenospheres are used in conductive coatings, tiles and fabrics.
6.Another use of it is in conductive paints for antistatic coatings and electromagnetic shielding.
