A free-lead and cadmium of antimony ruby glass composition and its preparation method

摘要

The antimony ruby glass is prepared by soda-lime silica system as matrix composition which coefficient of linear expansion is appropriate for the ordinary glassware. UV-VIS spectrometer is used to measure the transmittance curves of various amount Sb_2O_3 glasses Relation between amount Sb_2O_3 and transmittance of antimony glasses are investigated which indicates that the transmittance of antimony glass becomes lower with Sb_2O_3 amount increasing. Comparing un-treatment with heat treatment antimony glass, the dominate wavelength moves toward the red wavelength and the pure color increases.
