Elucidation of Slurry Drying Behavior Based on OCT In-situ Observation

Abstract

In wet forming of ceramics, cracking and deformation of the slurry during the drying process are critical issues. In this study, a technique for understanding drying behavior was developed by observing the internal structural changes of the slurry during the drying process using OCT, which can observe the inside of opaque objects, and by measuring the mechanical properties of the dried body using a nanoindentater, which can measure the microscopic mechanical properties. It was found that the mechanical properties of the dried body depended on the internal structural changes during the drying process caused by the type of binder added.
