Description
Aluminum Oxide (Al₂O₃) Micron Powder
Purity: 99.5+%
Particle Size: 1400–2000 µm
Product Description
Aluminum Oxide (Al₂O₃), also known as alumina, is a high-performance ceramic material valued for its exceptional hardness, dimensional stability, and chemical inertness. This micron-sized alumina powder (1400–2000 µm) offers excellent mechanical reinforcement and thermal resistance properties, making it suitable for a wide range of industrial and high-tech applications.
With a purity level of 99.5+% and low levels of impurities, this material is ideal for processes requiring high-quality refractory or structural components, as well as precision ceramic manufacturing. It also exhibits strong far-infrared emission, non-radioactivity, and absence of heavy metals, making it suitable for both technical and environmental applications.
