Based on the quantitative relationships between glass composition and glass Young’s modulus, density, chemical durability, viscosity, melting point, surface tension and devitrification, 10 glass compositions are selected as the optimum glass compositions of hollow glass microsphere used as ICF experiment target according to the requirements of high strength, high chemical durability, low melting point, low viscosity. Compared with the properties of other hollow glass micrespheres for ICF experiment, the chemical durability of the 10 candidate glass compositions is improved significantly, and the tensile strength of the 10 candidates is also increased remarkably. Moreover, the melting point, soften point and viscosity of the 10 candidates still satisfactorily meet the requirements of HGM fabrication in tower furnace. （From : No.1, 2006 Glass & Enamel）
