【摘要】 以Na2O-ZnO-SiO2系统磷酸盐乳浊玻璃为基础玻璃，通过加入混合着色剂CdS、Se粉使玻璃着色，对影响硫硒化镉着色乳浊玻璃稳定性的因素以及制备工艺进行了系统的研究，制备出颜色鲜艳均匀、理化性能良好的红色系列乳浊玻璃。借助XRD、SEM对玻璃试样进行物相分析和微观结构分析，采用抗折、强度测试、耐水性测试分析组成对玻璃理化性能的影响。研究了混合着色剂的加入量、配比以及热处理条件对玻璃显色的影响；探讨了ZnO的作用机理以及加入量对样品显色效果与性能的影响；研究了碱金属氧化物、熔制气氛对玻璃显色的影响。为生产硫硒化镉着色乳浊玻璃提供一定的理论指导，对于开发新型装饰玻璃材料具有实际意义。研究结果表明：着色剂Se、CdS的加入量分别为0.4wt%、1.8wt%时，能制备出颜色鲜艳均匀的红色乳浊玻璃，玻璃颜色随着色剂的掺入比例改变而变化，着色剂使用量越多，玻璃析出CdS、CdSe晶相越多，物化性能越好，硫硒化镉着色剂在一定范围内还能促进均匀分相；ZnO的主要作用是稳定着色剂CdS和Se，防止着色剂硒和硫的挥发，是制造硫硒化镉着色乳浊玻璃不可缺少的组分之一，加入量为16wt%左右，ZnO在该玻璃体系中属于网络形成体，随着ZnO含量的增加，玻璃的物化性能有所改善。采用着色剂CdS/Se与ZnO预煅烧、高温加料等工艺能有效减少着色剂的挥发；对组分相同的玻璃，随着显色热处理时间和温度的变化，玻璃的颜色会发生相应变化。热处理温度越高、热处理时间越长，则玻璃颜色越深，较好的显色温度、时间分别为600℃、2h；制备硫硒化镉着色乳浊玻璃必须为弱还原性气氛，采用添加少量金属锌粉作为还原剂，较合适添加量为1wt%；为了降低玻璃熔制温度，减少着色剂的挥发，玻璃组成中碱金属氧化物含量较高，加入两种碱金属氧化物Na2O、K2O，两者合适的加入比Na2O/K2O为1.2。更多还原

【Abstract】 The factors which affect the stability of the opaque glasses colored by CdS/Seand preparation process were studied. The glasses were colored by the addition ofmixed colorant CdS、Se based on Na2O-ZnO-SiO2phosphate glass system. Analysisthe phase and microstructure of the specimen with XRD、SEM. Investigate the effectof composition on the physical and chemical properties of the glasses by means ofthermal expansion analysis、strength analysis、water resistance analysis. The effects ofcolorant content and ratio and heat-treatment condition on the color of specimen werestudied. The mechanism and preferential content of ZnO、the content and ratio ofalkali oxide、the addition amount of P2O5emulsion、the atmosphere of the furnace onthe color performance were also be investigated. Thus provide theoretical guidance tothe manufacture of opaque glass colored by CdS/Se in an effort to produce red seriesopaque glass characterized by uniform color、favourable physical and chemicalproperties.The result show that red series opaque glass characterized by uniform color、favourable physical and chemical properties was obtained in the case of the additionof Se/CdS is0.4wt%1.8wt%respectively. With the variation of the ratio of CdS/Se,color of the glass specimen changed accordingly. The amount of the CdS，CdSecrystalline phase were increased with the increase of colorant amount which leads tothe improvement of the physical and chemical properties. The colorant CdS/Se can tosome degree induce uniform phase separation in glass. The role of ZnO is to stabilizethe colorant so as to prevent the evaporation of Se/S. ZnO is an indispensableingredient in the manufacture of colored opaque glass and the generally addition ofZnO is16wt%. ZnO was employed as network former in the present work and canimproved the physical and chemical properties. With the increase amount of ZnO，thecolorant which was stabilize by ZnO increased accordingly，thus the colorant amountremained in the glass increased.The evaporation of the colorant reduced effectively when using processes suchas the preheat treatment of CdS/Se with ZnO、high-temperature feed measure. Withthe variation of time and temperature of the heat treatment，the color of glass willchange correspondingly.When the temperature become higher，the time become longer，then the color of the glass become deeper. The preferential time andtemperature is2h and600℃respectively. To obtain acceptable color，the atmosphereof the furnace must be maintained as weakly reducing atmospheres. In the presentwork，Zn powder was employed as a reductant and the preferential content is1wt%.Strong oxidizing atmosphere or a strong reducing atmosphere will seriously affect thecolor performance. In order to decrease the melting point and reduce the lose of thecolorant，a large amount of alkali oxide was added to the composition. Base on theprinciple of mixed alkali effect，Na2O、K2O was used as fluxing agent and the bestratio of the Na2O、K2O is1.2.更多还原
