Overview

Oxoiron;oxo(oxoferriooxy)iron (CAS 12227-89-3) is a mixed-valence iron oxide compound with magnetic properties and high thermal stability. This iron oxide compound, also known by its molecular formula Fe3O4, represents one of the most important magnetic materials in industrial chemistry. With a molecular weight of 231.53 g/mol and EC number 235-442-5, this black crystalline solid exhibits unique properties that make it valuable across multiple industrial sectors. The compound consists of both ferrous (Fe²⁺) and ferric (Fe³⁺) iron ions in a spinel crystal structure, which accounts for its distinctive magnetic behavior and chemical stability. From a safety perspective, oxoiron;oxo(oxoferriooxy)iron is classified under ADR class 4.2, indicating its potential for spontaneous combustion under certain conditions, particularly when finely divided or in powder form. Despite this classification, the compound shows no specific GHS pictogram requirements, suggesting relatively manageable handling characteristics when proper industrial protocols are followed. Storage should maintain dry conditions to prevent oxidation and agglomeration. The compound finds extensive application in magnetic separation processes, where its ferromagnetic properties enable efficient recovery of metallic contaminants from various industrial streams. Additionally, it serves as a key component in advanced ceramics and electronic materials, where controlled magnetic permeability is essential. The catalytic industry also utilizes this iron oxide in various chemical processes due to its thermal stability and surface reactivity. Unlike organometallic compounds such as tris(2-methylpropyl)alumane or tripropylalumane, this iron oxide offers superior thermal resistance and environmental stability, making it particularly suitable for high-temperature applications. OYSI maintains reliable supply chains for this essential iron oxide compound to support European industrial requirements.
