Abstract

Silicon nitride may be densified by using mixed oxide additives which provide the conditions for liquid phase sintering of the ceramic. Fluoride added to M-Si- Al-O-N glasses allows a reduction in liquidus temperature. In the present study, sintering of silicon nitride with the addition of %7 Y₂O₃ + %7.2 MgF₂ and %7 Y₂O₃ + %5 MgO has been investigated with the aim of reducing the sintering temperature of silicon nitride by 100-150°C compared to Y₂O₃:MgO additives. The results show that the fluoride doped silicon nitrides have higher densities than the oxide-doped counterparts at temperatures up to 1650°C.
