橡膠工業用一氧化鉛The imported transparent glaze fired at lower temperature was analysed semi - quantitatively by adopting emission spectroscope. the stripping of lead and cadmium from this transparent glaze fired at lower temperature in ceramic product was determined by atomic absorption spectroscope. the effect of chemical composition on the stripping of lead and cadmium was analysed. upon the author s opinion, the overproof lead stripping from the imported transparent glaze fired at lower temperature can only be settled by adopting lead - free glaze instead of adopting low - lead prescription. the author succeeded in developing an excellent lead - free transparent glaze fired at the lower temperature of 1000 1050. the success is based on an inquiry into the feasibility of using such new agents of fusion as li2o and sro in replacement of pbo ; and on a study of the effects of the contents of sio2 , al2o3 , b2o3and other metallic oxides on such performances of glaze as coefficient of linear expansion, fusion temperature and transparency. it is also based on an analysis of coefficient of linear expansion of blank and glaze on an analysis of coefficient of linear expansion of blank and glaze on their correlation ; and on a study of technology for preparing glaze
