Abstract
Improved processes and products based on the discovery that metal atoms in complex relationship with complexing agents can be used to moderate the formation of organic salt seed crystals which promote an exceptionally well-ordered acicular growth of organometallic salts such as oxalates of the metal. Some acicular, i.e., needle-like, products have particular utility for being reduced to ferromagnetic metal particles which retain a surprisingly large degree of acicularity and possess extraordinarily favorable properties for use in magnetic recording applications.
