Floating beads/cenosphere/hollow microspheres in oil drilling
white cenosphere
1. Product name : cenosphere
Cenospheres are hollow ceramic microspheres found in fly ash, a natural by-product of coal combustion during
the generation of electric power. Small and hollow, microspheres are used as fillers or functional extenders in
the manufacture of plastics, paints, resins; light weight aggregates for cement, ceramics and other construction
products. Because Cenospheres often replace mined materials, they can significantly lower production costs.
Simultaneously, cenosphere can benefit finished product properties by increasing durability and better sound
proofing. Too, as material recycled from fly ash, cenosphere are environmentally friendly and help to preserve
natural virgin fillers.

Cenospheres have a variety of applications:
1.Cenospheres are hard and rigid, light, waterproof, innoxious, and insulative. This makes them highly useful in a variety of products, notably fillers.
2.Cenospheres are now used as fillers in cement to produce low-density concrete.
3.Recently, some manufacturers have begun filling metals and polymers with cenospheres to make lightweight composite materials with higher strength than other types of foam materials. Such composite materials are called syntactic foam. Aluminum-based syntactic foams are finding applications in the automotive sector.
4.Silver-coated cenospheres are used in conductive coatings, tiles and fabrics.
5.Another use is in conductive paints for antistatic coatings and electromagnetic shielding.
