Method and device for detecting open porosity of ceramic raw material formed by tape casting method

The invention discloses a method and a device for detecting the open porosity of a ceramic raw material formed by a tape casting method. According to the invention, an Archimedes drainage method is taken as a basic principle, air in the open pores is extracted in a vacuum infiltration manner, the open pores are filled with water to obtain a saturated sample, the dry weight, the hoisting weight in water and the wet weight in the air of the raw material sample are measured, whether the porosity of the raw material sample meets the standard can be detected, and the detection device is simple in structure and convenient to operate. The test method is convenient, fast and high in accuracy. 本发明公开了用于流延法成型的陶瓷生料开气孔率的检测方法及装置。本发明以阿基米德排水法为基本原理，通过真空浸润的方式将开气孔中的空气抽出，并用水填充得到饱和试样，测量生料试样的干重、在水中的吊重和在空气中的湿重，即可检测其气孔率是否符合标准，检测装置结构简单，测试方法方便快捷、准确度高。
