1µm Single-Crystal Aluminum Nitride (AlN) Powder – High Thermal Conductivity AlN Filler for TIM & Electronic Packaging

F-01 is a single-crystal aluminum nitride thermal filler powder with a D50 of approximately 1μm. As a single-crystal product, F-01 offers higher purity and fewer grain boundary defects, making it particularly suitable for thermal management applications that demand stringent material quality and reliability. With its combination of high thermal conductivity and electrical insulation, it serves as an AlN high thermal conductivity insulating filler for advanced electronic systems.

 

In particle size distribution design for composite materials, the 1μm fine powder plays a key role in "filling the gaps between coarse particles." When combined with larger particle size fillers, it effectively increases packing density and particle-to-particle contact points, thereby further enhancing the overall thermal conductivity of the composite.

 

F-01, as a 1μm Single-crystal aluminum nitride thermal filler powder, is ideal for TIM applications that demand high thermal conductivity and stable quality. As an AlN semiconductor packaging filler, it delivers superior packing efficiency and thermal performance for advanced electronic packaging. When used in combination with coarse powders, it provides excellent filling efficiency and thermal conductivity, making it an essential fine powder component in precision particle size distribution formulations.
