碩士 === 國立成功大學 === 化學工程學系碩博士班 === 98 === Process development for combustion synthesis of AlN powder using Al reactant with different morphology. The reactant of experiment is different from the aluminium powder used in laboratory, the raw materials used are A-2 and A-3. A-2: The raw materials used are the 75 μm flaky aluminium powder, using programmble temperature and humidity chamber to take the surface treatment of aluminium powder. A combustion synthesis reaction was ignited by heating and lead air to fire, produce AlN under the appropriate reaction condition, the conversion ratio of product is in above 99. A-3: 15 ~ 85 μm gray irregular particle form aluminium powder, added with aluminium nitrogen process a combustion synthesis reaction, then produce AlN. The conversion ratio of product is 97.97. It is APS, GPS and phosphoric acid to take the nitrogen aluminium powder surface treatment used in the laboratory, analyze its ESCA picture, and then analyze ESCA picture of the commercial aluminium nitrogen powder.
