High-purity aluminium oxide (99.999 %) represents electronic-grade oxide feedstock, widely adopted in semiconductor manufacturing, sapphire substrates, optical coatings, advanced ceramics and high-brightness LED substrates. At 99.999 % purity total metallic impurities are constrained below 10 ppm, placing high demands on cross-validated analytical capabilities (ICP-MS / GDMS). Multiple grades from nano- to micron-sized powders are offered with precise particle-size tuning down to 0.1 μm, 0.5 μm, 1 μm. Every batch undergoes closed-loop full-process quality management from raw-material to finished-goods to secure consistent impurity-levels and particle-size distributions, enabling electronic-materials procurement managers to safeguard production-line yield through stable quality.

Aluminum oxide alpha-phase 99.999% (metals basis)
Aluminum Oxide (Al2O3) is a white or nearly colourless crystalline substance, and a chemical compound of aluminum and oxygen. It is made from bauxite and commonly called alumina and may also be called aloxide, aloxite, or alundum depending on particular forms or applications. Al2O3 is significant in its use to produce aluminum metal, as an abrasive owing to its hardness, and as a refractory material owing to its high melting point.
