The present work indicates through thermodynamic considerations that YLiO{sub 2} additive is beneficial for low-temperature sintering of AlN ceramics. Pressureless sintering of commercially available AlN powders with simultaneous additions of YLiO{sub 2} and CaO resulted in materials with high thermal conductivity (170 W{center_dot}m{sup {minus}1}{center_dot}K{sup {minus}1} after sintering at 1,600 C for 6 h). It is demonstrated that improvement of thermal conductivity is possible at low firing temperature by use of sintering aids.
