Preparation and Characterization of a New Layered Magnesium ...

A new hydrated phosphate of magnesium with a layered structure was prepared hydrothermally under mild conditions. Provided it is not heated beyond 200°C, this solid undergoes reversible dehydration-rehydration with the layered structure remaining intact. The as-prepared precursor is orthorhombic ( a = 9.274, b = 8.053, and c = 10.920 Å), the likely space group being P2 12 1 ...
