Abstract

Preliminary treatment in hydrogen for aluminum nitride powders (before hot pressing) affects the strengthening and structuring of the ceramic. There is a positive effect from the gas heat treatment on account of recrystallization during sintering and increase in plasticity of the aluminum nitride due to the hydrogen dissolved in the lattice.
