Cenosphere

Cenosphere 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; Lightweight aggregates for cement, ceramics and other construction products. Because Cenosphere 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.
