Preparation and properties of metallic iron ferrofluids

A stable hydrocarbon based metallic iron ferrofluid has been produced by the decomposition of enna-carbonyldi-iron. After five months only about 4% of the iron had oxidised. From magnetic and electron microscopy studies a median particle diameter of less than 50 angstrom has been found. The distribu...

Description
Summary:A stable hydrocarbon based metallic iron ferrofluid has been produced by the decomposition of enna-carbonyldi-iron. After five months only about 4% of the iron had oxidised. From magnetic and electron microscopy studies a median particle diameter of less than 50 angstrom has been found. The distribution of particle sizes is relatively narrow.
