· Fe2O3

Iron oxide (Fe2O3), commonly known as hematite, is a naturally occurring ceramic semiconductor with significant structural rigidity and moderate ductility. It is widely used in pigments, catalysts, and magnetic applications across chemical processing, construction, and electronics industries, where its corrosion resistance, thermal stability, and abundance make it a cost-effective choice for high-temperature and corrosive environments. As a semiconductor, Fe2O3 is also gaining traction in photocatalysis and photoelectrochemical water splitting research, positioning it as a promising material for sustainable energy applications where its bandgap and electron transport properties offer advantages over competing oxides.

Regulatory Screening

Environmental

Export Control

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
