Aluminium Oxide (Calcined) – LR Grade, 500g (Alumina)

Aluminium Oxide Calcined, also known as Alumina, is a high‑purity inorganic compound supplied in a 500g pack and manufactured to Laboratory Reagent (LR) grade. The calcined form has been heat‑treated to produce a hard, chemically stable material, making it ideal for use in educational science laboratories.

Identified by CAS Number: 1344‑28‑1 and with no UN number, aluminium oxide is not classified as hazardous for transport when handled appropriately. It is a white, insoluble powder with excellent thermal stability and chemical resistance, widely used to support teaching in inorganic chemistry and materials science.

Supplied in a generous quantity for repeated classroom use, Aluminium Oxide Calcined LR Grade is easy to store, measure, and incorporate into a wide range of practical investigations.
