Structural changes accompanying the sintering of ultrafine aluminum nitride powders

A study of the structure of an Aln-based ceramic obtained from ultrafine powders

“…[5], the processes of dissociation and evaporation of AIN take place at and above 1700~ Apparently, the chemical composition of AIN does not change during this process.…”

“…In a study of the sintering kinetics of the plasma-chemical powders, Kuzenkova et al [5] observed unusual regularities of their shrinkage and recrystallization and certain structural features of the sintering process of AIN in nitrogen atmosphere in the I000-1900=C range. Their high purity and increased reactivity make it possible to develop virtually pore-free materials.…”
