Description

Aluminum Oxide (Al₂O₃) Micron Powder – Purity: 99.5+%, Size: 1000–1400 μm

Coarse-Grade High Purity Alumina for Structural & High-Temperature Applications


Product Description

Aluminum Oxide (Al₂O₃) Micron Powder, in the coarse size range of 1000–1400 μm, offers exceptional thermal stability, abrasion resistance, and chemical inertness. With a purity of 99.5+%, this grade of alumina is ideal for demanding applications in refractory systems, abrasive blasting media, and high-strength ceramic components. It is also used in catalysis, polishing, and thermal insulation due to its superior infrared emission characteristics and non-toxic nature.
