The glass beads, composed of SiO2,Na2O and CaO, are broken and calcined by high temperature after which the said microspheres are obtained. With properties of the high roundness rate, better hardness, excellent anti-friction and direct reflect light ,etc, they are widely applied in the fields of plastic rubber, abrasion ground, blast derusting , road-reflect dope and handicraft lamp, etc
