A Free-Lead and Cadmium of Antimony Ruby Glass Composition and its Preparation Method

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 Sb2O3 glasses Relation between amount Sb2O3 and transmittance of antimony glasses are investigated which indicates that the tSuperscript textransmittance of antimony glass becomes lower with Sb2O3 amount increasing. Comparing un-treatment with heat treatment antimony glass, the dominate wavelength moves toward the red wavelength and the pure color increases.
