Abstract

The gradual pressure induced oxidation of Fe²⁺ to Fe ³⁺ was determined at various pressures and temperatures. The phenomenon of self-oxidation in Fe(OH)₂ is attributed to the gradual lateral displacement of the H atom due to Coulomb repulsion. The self-oxidation led to the creation of a new electron band within the HP band structure of Fe(OH)₂. It was found that the oxidation process is not reversible by decompression due to low affinity of Fe³⁺ reduction to Fe ²⁺.
