摘　　要：以德化等地生产的新型环保陶瓷为主要研究对象,进行不同温度、时间的酸侵蚀实验。采用波长色散X荧光、扫描电子探针、X衍射等分析技术,对样品化学组成、显微结构、物相组成等性能进行测试分析,初步探明了日用陶瓷的风化机理及影响其风化速度的主要因素,研究还首次发现德化生产的轻质白陶制品废弃丢后,在较短时间内可自然风化降解。Experiment acid etching at different temperatures and for different times were carried out on the light weight white pottery from Dehua. WDXRF, SEM and XRD were used to analyze the composition, microstructure and phase composition of the light weight white pottery samples. Weathering mechanism and the main factors affecting weathering velocity of the domestic ceramic were preliminarily explored. Furthermore, it was first found that the waste light weight domestic ceramics can be weathered and degraded naturally in a short time when it is abandoned in the open air.
