Silica powder/silicon dioxide/precipitated silica for glass microsphere
 Glass microphere |  Silica |
Glass microspheres are microscopic spheres of glass manufactured for a wide variety of uses in research, medicine, consumer goods and various industries.
The hollow glass microspheres can be used in paint and coatings, construction sealant, rubber, plastic, FRP, artificial stone, putty and other products as filler and weight-reducing agent. The glass bubbles can also be used to produce high-strength, low-density cement slurry and low-density drilling fluid in oil and gas extraction industry. more and more industries now trying to testing the hollow glass spheres as additives to improve their products' properties.
Silicon dioxide is the main raw material of glass microphere,it is widely used to produce glass beans.
