Iron (III) Oxide (Calcined Red) – 500g (LR Grade)

Iron (III) Oxide (Calcined Red), also known as Ferric Oxide, is a high‑purity inorganic compound supplied in a 500g pack, ideal for routine use in school laboratories. This product is provided in Laboratory Reagent (LR) grade, making it suitable for teaching, demonstrations, and standard practical experiments within educational science settings.

Identified by CAS No. 1309‑37‑1, Iron (III) Oxide is a stable, red‑brown powdered solid commonly encountered in both chemistry and materials science. As it is not classified for transport (UN: NR), it is easier to handle and store than many reactive chemicals, while still providing excellent educational value.

This reagent is widely recognised for its role in demonstrating the properties of metal oxides and is frequently used in experiments involving thermal reactions, oxidation processes, and the extraction of metals. Its clear labelling supports safe handling in accordance with school laboratory policies and COSHH guidance.
