Summary: | 碩士 === 國立成功大學 === 化學工程學系 === 89 === This thesis successfully develops the technique to manufacture water-resistant and surface-modified aluminum nitride(AlN) powder. This thesis includes four parts. Part A, B, and C describe the technique of coating ceramic materials on aluminum nitride powder. Part D describes the technique of coating thermal-setting plastics on aluminum nitride powder.
In part A, we coat ceramic materials on AlN powder with milling-and-coating -simultaneously technique. It was found that the silica-coated AlN powder presents predominant water resistance after 85HT test. However the titania-coated powder was still hydrolyzed after 85HT test. In part B, we coat ceramic materials on aluminum nitride powder by the means of sol-gel technique. It was found the silica-coated powder presents very excellent water resistance after heat-treatment. In part C, we coat AlN powder with Zr(NO3)4 solution. It was found that the higher the heat-treatment temperature, the more excellent water resistance that the coated powder present. In part D, we develop the technique to coating thermal-setting plastics on AlN powder. It was found that the coated powder presents very excellent water resistance by this method.
