| Research Abstract |
We developed a novel ceramic forming process by surface hydration of particles through microwave irradiation. In this process, irradiating a green body with microwaves enhances the hydration reaction between water and particle surfaces, creating surface aluminum trihydroxides structure of adjacent particles that bind together tightly. The key point of improvement in binding strength on this process was enhancement of surface hydration reaction. In this research, we investigated that effects of mechanical surface treatment on the microwave absorption properties of alumina powder surfaces. The dielectric loss of alumina powder was increased by the surface treatment using planetary ball mill, as a result, the microwave absorption of surface treatment powders was carried out effectively. It was considered that treated powders surface was heated locally and it is thought that a hydration reaction of powder surfaces was promoted and mechanical property of green body was improved.
