Deltoidal Icositetrahedron Faceting on Alpha-Iron Crystals from the Moon's Surface

Explore a 26-minute video analyzing the crystallographic structure of micron-sized single crystals of body-centered cubic iron discovered on the lunar surface. Delve into the unexpected deltoidal icositetrahedron faceting behavior observed, which is best described by planes of the {229} form. Understand how this unique faceting can be rationalized based on the local chemical conditions experienced during crystal growth in the lunar environment. Gain insights from the scientific paper published in the Journal of Crystal Growth and learn about the research of Dr. Kevin Knowles and Prof. Sir Harry Bhadeshia in this fascinating study of extraterrestrial iron crystals.
