Superior Thermal Conductivity for Demanding Electronics
Our D50 Aluminum Oxide Ceramic Powder (Alpha Alumina) is a high-purity, spherical powder engineered for advanced thermal management solutions. With a consistent spherical morphology and tightly controlled particle size distribution, it enables superior filler loading in thermal interface materials (TIMs), resulting in exceptional heat dissipation for modern electronics.
Key Features & Benefits:
High Purity & Performance: ≥99.5% Al2O3 content ensures excellent electrical insulation and optimal thermal performance.
Spherical Morphology: Perfectly round particles reduce viscosity, improve flowability, and allow for high packing density in composites.
Controlled Particle Size (D50): Available in standard D50 sizes from 5μm to 70μm for precise formulation and efficient filling of microscopic gaps.
Enhanced Thermal Conductivity: High filler loadings directly translate to superior heat conduction in polymers and gels.
Customizable Grading: Particle size distribution can be adjusted to meet specific application requirements.
