Description
Aluminum Oxide (Al₂O₃) Micron Powder – Purity: 99.5+%, Size: 350–500 μm
High-Purity Large-Particle Alumina for Advanced Industrial Applications
Product Overview
This 350–500 μm Aluminum Oxide Micron Powder is designed for applications that demand robust particle integrity, superior wear resistance, and excellent thermal properties. Its relatively large particle size and high purity make it especially valuable for structural ceramics, high-temperature crucibles, and abrasive applications requiring minimal contamination.
