Aluminum Nitride (AlN) Powder, >99.9%

Product Description

Our high-purity aluminum nitride (AlN) powder (99.9% minimum purity) provides a reliable ceramic material for semiconductor processing, optical component manufacturing, thermal interface systems, and advanced electronic packaging. Engineered for low metallic contamination with Fe < 80 ppm, the powder exhibits excellent thermal conductivity, electrical insulating properties, and consistent particle morphology suitable for high-performance materials fabrication.

Supplied as a free-flowing micron-grade powder with controlled agglomeration, this material is ideal for substrate manufacturing, high-temperature ceramics, dielectric components, thermal management systems, and optical-grade composite formulations requiring low impurity loading and stable bulk properties.
