摘　　要：采用熔融法制备了SiO 2-B 2O 3-ZnO-K 2O-BaO系彩釉玻璃基料,利用XRD、SEM、综合热分析、高温润湿角测量等手段研究了CeO 2添加量对玻璃基料相组成、显微形貌、热膨胀系数、特征温度和与钠钙玻璃的润湿性的影响。研究结果表明:当CeO 2的添加量高于3%(质量分数,下同)时,水淬后的玻璃基料样品在700℃进行钢化处理后,样品中会有CeO 2晶体析出。随着玻璃基料中CeO 2添加量的增加,样品的耐酸性、与钠钙玻璃润湿性和抗弯强度都先增强后降低。当CeO 2的添加量为1%时,样品与钠钙玻璃的润湿性最好,其润湿角取到最小值45.6°;当CeO 2的添加量为3%时,样品在5%(质量分数)的稀硫酸溶液中失重率取到最小值2.83 mg/cm 2,玻璃的耐酸性最好;当CeO 2的添加量为4%时,样品的抗弯强度最大,为75.69 MPa。结果表明,加入2%CeO 2的基料综合性能最优,具有良好的应用前景。The base materials of SiO 2-B 2O 3-ZnO-K 2O-BaO enameled glass were prepared by melting method.The effects of CeO 2 addition on the phase composition,microstructure,thermal expansion coefficient,characteristic temperature and wettability with soda lime glass were investigated by XRD,SEM,comprehensive thermal analysis and high temperature wetting angle measurement.It was found that when the addition amount of CeO 2 was higher than 3wt%,there would be precipitation of CeO 2 crystal in the samples after tempering at 700℃.With the increase of CeO 2 content in the glass matrix,the acid resistance,wettability with soda lime glass and bending strength of the sample increased first and then decreased.When the addition amount of CeO 2 was 1wt%,the wettability between the sample and the soda lime glass was the best,and its wettability angle reached the minimum value of 45.6°.When the addition amount of CeO 2 was 3wt%,the weight loss rate of the sample in the 5wt%dilute sulfuric acid solution reached the minimum value of 2.83 mg/cm 2,and the acid resistance of the glass was the best.When the addition amount of CeO 2 was 4wt%,the sample had the best bending resistance,and its strength was 75.69 MPa.The results show that the base material with 2wt%CeO 2 has good comprehensive performance and good application prospect.
