Cenosphere are lightweight, inert, hollow, nonmetallic spherical materials, composed largely of silica (SiO2) and alumna (Al2O3) compositions of Cenospheres are similar with glass and ceramic.
1.Those hollow glass particles have also been called hollow ceramic spheres and micro spheres.
2.Due to their unique combination of spherical shape, high strength in compressing, good sound and thermal insulation,
Cenospheres are utilized as a high performance filler material, that can replace other mineral filler.
