Ideal Crystal

 

(1) A crystal of perfect structure, with none of the structural defects inevitable in real crystals. The ideal crystal is a theoretical model widely used in solid-state theory.

(2) A crystal of perfect shape in which physically equivalent facets are identically developed. Crystals close to the ideal are grown in suspension in a well-mixed supercooled solution.
