(Phys.org)—New research by a group from Hokkaido University in Japan has shown that the plastic ionic crystal, quinuclidinium perrhenate, has ferroelectric properties and can serve as a model for ...

Remember that the lattice arrangement is giant - for example, a single grain of salt may contain 1.2 × 10 18 (1,200,000,000,000,000,000) ions. The lattice arrangement continues in three dimensions.

The study of crystal growth and characterisation of fluorite-like compounds has garnered significant attention owing to their unique structural features and promising functional properties. These ...
