摘　　要：通过泛霜试验,结合XRD衍射图谱分析对掺入不同造孔剂制品的泛霜物质进行了研究,得出:制品干燥室"泛白"主要是由Na2SO4结晶引起的,可实施快速干燥加以消除;以CaCO3作造孔剂制品烧成后泛霜是由其中可溶盐硫酸钙结晶引起的,不易彻底消除。Study is made on efflorescence samples adding different pore-creating agents through efflorescence test and incorporation with analysis of XRD. The result shows that： The ＂dryer white＂ on sample＇s surface was caused by crystallization of Na2SO4 at dry stage,which can be dispelled through quickdrying：the efflorescence on burned body was caused by crystallization of solubility Ca^2＋,which is difficult to dispel thoroughly.

关 键 词：泛霜 干燥室“泛白” 造孔剂
