Effect of classified aluminum nitride whisker addition on densification and mechanical strength of low-temperature-sintered aluminum nitride ceramics

Year: 2024

Type: article

Abstract: We investigated the effects of adding classified small-sized AlN whiskers during the fabrication of low-temperature-sintered AlN ceramics on the densification and mechanical properties. The samples without the whiskers had low mechanical strength due to low-temperature sintering, but the addition of the whiskers increased the mechanical strength. Adding unclassified whiskers decreased the relative density and created voids among the particles. In contrast, the addition of classified small-sized whiskers resulted in a higher relative density and a clear increase in mechanical strength.
