Cenospheres are alumina or silica balls mainly filled with inert gas or air. The name is derived from the two Greek words kenos and sphaira which describe the material quite well. Cenospheres are light in weight and hollow and are produced as a result of the combustion of coal. These are used these days to produce concrete of low density by using them as cement fillers.
