Abstract：The structure and development history of hollow glass microbeads, preparation methods of hollow glass microbeads of glass powder method, spray granulation method, liquid drop method, dry gel method, and soft chemistry method, and the application of plastic, rubber, resin, emulsion explosive, coating, electromagnetic shielding and microwave absorption were summed.It is proposed that hollow glass beads have the advantages of light weight, high strength, good fluidity, heat insulation, corrosion resistance and so on.They are playing an increasing role in the development of heat insulation, wear resistance and other composite materials, and their applications in the new energy industry and biological materials are also developing rapidly.It is thought that In terms of compressive strength and particle size, hollow glass beads cannot reach the level of high strength and fine particle size of high performance beads, and the chemical stability and fine control degree of microbeads are also deficient.The studies of the improvement of raw material formula, optimization of production process, and improving post-treatment technology, as well as the whole sea deep buoyancy materials, heat insulation coating, and emulsion explosive applications should be further carried out.
