SEPPE cenosphere,Like fly ash, they are naturally occurring by-products of the burning process at coal-fired power plants. Unlike fly ash though, cenospheres are lightweight, inert, hollow spheres comprised largely of silica and alumina and filled with air and/or gases. Since they are inert, they are not considered a pozzolan. And because they are very small and have high compressive strengths, cenospheres can be used as a structural lightweight filler.

Main Application


Cenospheres in Paints and Coatings

There are a great many uses for cenospheres in the paint and industrial coating industry, due to the additional qualities they provide. For example, cenospheres are often used in coatings to control infrared radiation, giving those coatings an advantage over ones that merely attempt to limit thermal conductivity.


Cenospheres in Syntactic Foams

Cenospheres are often used to make ‘syntactic foams’. These are specialized solids which use cenospheres as a filler to provide any number of advantages, from lower cost, to added strength, sound proofing, buoyancy and thermal protection.


Cenospheres in Oilfield

In the oil and gas industry aluminosilicate microspheres (cenospheres) are used as an additive in drilling mud when drilling wells for various purposes. This application significantly increases the efficiency and service life of the drilling equipment.In addition, drill microsphere solutions also increase the intensity of the drilling wells.


Cenospheres in heat-insulating refractory concretes

Microspheres, due to their fire resistance and high heat-insulating properties, are used in the production of thermal insulation materials. The high temperature of microsphere shell softening allows, with the appropriate selection of the binder, creating refractory coating and insulating materials for industrial equipment.
