Cenosphere

We are offering cenosphere.
A cenosphere is a lightweight, inert, hollow sphere comprised largely of silica and alumina and filled with air andor gases. Cenospheres are a naturally occurring by-product of the burning process at coal-fired power plants, and they have most of the same properties as manufactured hollow-sphered products
