Abstract: Using high temperature melting method , in the system of sodium borosilicate glass doped with rare earth and metal oxide was prepared by uv-infrared strong absorption of energy conservation and environmental protection glass, and researched the different amount of rare earth and metal oxide doped glass optical, thermal and structure, etc.The research shows that, under the precondition of ensuring certain visible light transmittance, the uv-infrared absorption can be enhanced by regulating the amount of rare earth and metal oxides.With the increase of total doping of CeO 2 and TiO2 , the ultraviolet-transmittance of glass decreased significantly with the increase of doping , while the near-infrared transmittance increased.With the increase of the total doping of Fe 2 O3 and SnO2 , the ultraviolet-visible and near-infrared transmittance of glass decreased significantly with the increase of doping .When the quality percentages of CeO 2 , TiO2 , Fe2 O3 and SnO2 were about 0.6％, 1％, 0.6％ and 1％respectively, the average transmittance of Tuv was less than 5％, and the average transmittance of Tir was less than 20％.At the same time, this sodium borosilicate glass pyrology and mechanical properties are better than normal sodium calcium silicate glass .
