Abstract (en)
[origin: WO2013171324A1] The invention concerns silicon nitride ceramics, which especially can be produced by adding only the slightest amounts of sintering additives, resulting in ceramic bodies comprising very little grain boundary phase. The invention further concerns a method for producing such Si3N4 ceramics.
