The purpose of the paper is to research and create LiAlO2 powder applied in measuring photon and neutron dosimetry. In this work, we developed of process for the synthesis of lithium aluminate powder using sol-gel method. The key steps involved in the synthesis of powders were: (1) preparation a sol from lithium and aluminum nitrate as starting materials; (2) formation of gel powders and (3) calcination of gel powders to the oxide powders. |
