The development of the hollow glass microballoon began in the ’50 s, according to world patent database statistics, more than 20 years, both at home and abroad relating to the hollow glass microballoon invention has more than 50 (most of the basic patent).Half of them for the preparation of the hollow glass beads and the other half for its application. Nearly a decade involving patent less than one-third of the preparation of hollow glass beads, the remaining two-thirds for the application. Visible, hollow glass beads has entered the stage of application development.
Hollow glass microsphere, the earliest is mainly used in space industry, defense industry and other cutting-edge science and technology. With the development of science and technology and the realization of the hollow glass beads industrialized mass production, as well as the application of hollow glass bead extraction technology of fly ash hollow glass beads material has become a low cost, rich resources of new materials, widely used in thermal insulation fireproof materials, advanced insulation materials, emulsion explosive, composite materials, petrochemical, chemical additives, such as military, general other technical areas.
