Aluminum Nitride (AlN) Filler
Aluminum nitride is a material characterized by high thermal conductivity and insulation properties, and is used as a heat-dissipating filler mixed into resins.
With the increasing demand for heat dissipation performance due to the miniaturization and high-density integration of electronic devices, there is active consideration of switching from currently used silica and alumina powders to aluminum nitride powder.
MARUWA offers a lineup of aluminum nitride fillers with different particle sizes for high thermal conductivity Thermal Interface Material (TIM) applications.

Surface Treatment
Aluminum nitride powder undergoes a hydrolysis reaction, as shown in equation (1), which results in a reduction in thermal conductivity.
AlN + 3H2O → Al(OH)3 + NH3 …… (1)
MARUWA's aluminum nitride fillers can be treated with water resistance for all grades.
