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.

提出了一种微波辐射下颗粒表面水化的陶瓷成型新工艺。在该过程中，用微波照射绿色体增强了水和颗粒表面之间的水合反应，产生紧密结合在一起的相邻颗粒的表面三氢氧化铝结构。该工艺提高胶凝强度的关键是促进表面水化反应。本研究主要探讨机械表面处理对氧化铝粉体微波吸收特性之影响。采用行星式球磨机对氧化铝粉体进行表面处理，提高了氧化铝粉体的介电损耗，从而有效地发挥了氧化铝粉体的微波吸收作用。认为处理后的粉体表面局部受热，促进了粉体表面的水化反应，提高了绿色坯体的力学性能。
