What is hBNxAlN?
hBN x AlN (hBNxAlN)
hBNxAlN is a reusable hBN and AlN hybrid thermal filler route for insulating thermal systems, TIMs, gap fillers, and thermal coatings.

What It Is Not
- hBNxAlN is not hBN or AlN alone; it is a hybrid electrically insulating thermal-filler route.
When Not to Use It
- Do not use hBNxAlN when electrical conductivity is required or when the process cannot tolerate high ceramic loading and hybrid-filler rheology.
Intrinsic Screening Summary
- Identity screen
- Hexagonal boron nitride and aluminum nitride hybrid; Hybrid insulating ceramic thermal filler
- Intrinsic feature
- Hybrid ceramic filler packing can improve thermal pathways while maintaining electrical insulation when filler loading and interface wetting are controlled.
- Material-level integration
- Match particle packing, surface treatment, viscosity, bondline thickness, and electrical insulation requirements to the host polymer or binder. Use when the thermal path must stay electrically insulating.
