its most distinctive property: at around 170 W\/(m\u00b7K), it is many times higher than that of aluminum oxide, reaching values \u200b\u200bthat are exceptional for an electrically insulating ceramic. It is determined by the non-oxide crystal lattice and the additives added during sintering: a low-oxygen microstructure is crucial, as dissolved oxygen disrupts heat transfer within the crystal lattice. Sintering additives such as yttrium oxide bind this oxygen and significantly increase the thermal conductivity of aluminum nitride. Precisely for this reason, it is highly sensitive to powder purity and process control, and these two parameters can be precisely tailored to its properties.<\/p>\n<\/div><\/section><br \/>\n\n<style
