摘要
PURPOSE:To provide the titled glass beads for recurrent reflection having an improved color tone. an improved melting temp. and a special composition consisting of TiO2, BaO, PbO, SiO2, ZrO2, CaO, ZnO, K2O, Na2O and B2O3. CONSTITUTION:44-50wt% TiO2, 20-28% BaO, 8-20% PbO, 0-2% SiO2, 3- 8% ZrO2, 0-3% CaO, 3-9% ZnO, 0-3% K2O, 0-2% Na2O and 0-2% B2O3 are melted at 1,200-1,250 deg.C to obtain glass beads for recurrent reflection having =2.20 refractive index.
