摘　　要：用CeO2及TiO2混合着色可以生产金黄色的玻璃,铈的用量及玻璃配合料氧化还原性都容易造成玻璃光学指标及色度指标的改变,使玻璃产生较大的色差。通过改变玻璃中铈的用量和氧化还原剂用量熔制玻璃样片,然后用CARY500分光光度计对玻璃样片进行光度及色度指标分析。结果表明:着色剂的用量、配合料的氧化还原性、萤石的添加量对玻璃的光学指标及色度指标都有较大影响。A golden glass was produced by combined coloration of CeO2 and TiO2.The amount of CeO2 additive and redox of the glass batch affect the optical properties and chromaticity of glass so that large chromatic-aberration appears.By changing Ce addition and redox agent in glass batch a splendid golden glass sample was obtained.The spectra and chromaticity analysis was carried out by using CARY500 spectrophotometer.Results indicate that the optical properties and chromaticity of this new golden yellow glass are highly dependent on those factors,such as,amount of colourants,oxidation-reduction of glass batch and addition of fluorite.
