Rare Epsilon-Phase Iron Oxide: What Ancient Chinese Potters Knew That Modern Science Wants To Duplicate

A new analysis of ancient Jian wares reveals that the distinctive pottery contains an unexpected and highly unusual form of iron oxide - a rare compound called epsilon-phase iron oxide which was only recently discovered and characterized by scientists and so far has been extremely difficult to create with modern techniques. Understanding 1,000 year old synthesis conditions used by Chinese potters could lead to an easier, more reliable synthesis of epsilon-phase iron oxide, enabling better, cheaper magnetic materials - including those used for data storage. read more
