【摘要】用溶胶凝胶法制备了不同晶型和晶粒尺寸的A1203纳米粉末样品,分析了反应过程中各因素对产物形态的影响。对所制得样品的红外吸收能力进行了研究。结果表明,样品的红外吸收能力对其晶型和晶粒尺寸具有一定的依赖性。更多还原

【Abstract】 Nanoscale alumina grain with different crystal structures and various sizes have beenprepared by using Sol-gel method. Influences of condition parameters in the process on the samples werediscussed. IR absorbency of samples was studied. It is shown that the IR absorbency will be changedwith the crystal structure and grain size of samples.更多还原
