Preparation of high purity berlinite |
摘要 |
High purity berlinite is prepared by formation of an organoaluminum phosphate hydrogel in an organic solvent and subsequently hydrolyzing the hydrogel by reaction with water at pH less than or equal to 3.0. The berlinite is useful as a replacement for silicon-based quartz in electronic applications and in piezoelectric devices.
