Extra-pure zinc sulfate is the principal matirial in the preparation of phosphor for color-television.However,its quality greatly degrades when trace impurities are present.Ion exchange is an excellent method for its puri- fication and has been investigated ever since 1951.But this method has not been extensively used on a large scale,because the ion exchanger used is diffi- cult to be regenerated.In present investigation we solved the problem of re- generation of the ion exchanger by the application of coordination...

Extra-pure zinc sulfate is the principal matirial in the preparation of phosphor for color-television.However,its quality greatly degrades when trace impurities are present.Ion exchange is an excellent method for its puri- fication and has been investigated ever since 1951.But this method has not been extensively used on a large scale,because the ion exchanger used is diffi- cult to be regenerated.In present investigation we solved the problem of re- generation of the ion exchanger by the application of coordination chemistry. We found'that the blue phosphor prepared by our method is superior to that prepared by the prevalent pracipitation method in all of its qualities.

超纯硫酸锌是制备彩色电视荧光粉的主要原料,硫酸锌含有痕量杂质就使质量大大下降。离子交换法是提纯硫酸锌极好方法,自1951年即已开始研究。但因离子交换剂难于再生,故此法尚未推广。本文用络合物化学理论解决了离子交换剂的再生问题,甩本法制得的蓝色荧光粉与目前通用的沉淀法相比,各项质量指标均较优越。

A preliminary study on several Jun ware sherds was completed in september 1981.Fourtypes of characteristic structure existing in Jun glaze were confirmed, with convincingevideaces of liquid phase separation structures in the glaze. Based on these results, eleventypical Jun sherds of the Song and Yuan Dynasties were collected and investigated. The chemical compositions of the eleven samples, both of the glaze and body weregiven.The glaze and body formulas in different periods of the Song and Yuan Dynastieswere compared respectively. The optical properties and element constituents of the interlayer between the glaze andthe body were studied by optical microscopy (OM) and energy dispersion X-ray spectrometer(EDX) respectively which brings the conclusive results that the interlayer is ananorthite crystalline layer produced due to the reaction between the glaze and the body.For all the specimens, liquid phase separation structures were observed generally by DTEMand a systematic measurement of liquid droplet size distribution was carried out.The globaldroplets and the r<λ (~500A) conform to the critical condition for Rayleigh scattering. Abrief explanation to opalescent mechanism of Jun glaze was given in accordance with Ray-leigh theory. Cubic crystallites of cuprite (Cu_2O) were discovered to be existing in red Jun glaze ofthe specimens which were thinned by ion bombardment as observed with DTEM and ana-lysed with EDX.Hence an inference can be drawn from these results that the red liquidphase droplets contain Cu~+ ion, which causes coloration by selective absorbing and scat-tering of incident light waves. The greyish blue particles in the red region were found and investigated by STEM,EDX and ED and proved to be small polycrystalline particles of chalcocite (Cu_2S), whichcontrols the coloration of Jun glaze from violet to red as a result of different proportions ofparticles and droplets. The mechanism of coloration of Jun ware is thus solved and the door to further inves-tigation of coloring mechanism of copper red glaze is now opened. Finally, three possible sources of sulfur are discussed briefly. We conclude that sulfurcontaining copper ore may be one of the raw materials used in the manufacturing of thered Jun glaze in the Song and Yuan Dynasties.
