Description
Aluminum Oxide (Al₂O₃) Micron Powder
Purity: 99.5+%
Particle Size: 1–10 μm
Product Description
Aluminum Oxide (Al₂O₃), commonly known as alumina, is a high-performance ceramic material recognized for its extreme hardness, chemical stability, and excellent thermal resistance. In its micronized powder form (1–10 μm), it provides superior dispersibility and integration across various technical and industrial applications. With a purity of 99.5+%, this alumina grade ensures consistent performance and is free from radioactive or carcinogenic substances.
This material features high dimensional stability, infrared emissivity, and low levels of heavy metals, making it a preferred additive in ceramics, electronics, catalysis, and composite materials. It also serves as a reliable catalyst support and as a thermal insulation component in textiles and lighting applications.
