Thermal stability of rare earth densified ?-sialon ceramics
(1997)
Typical ?-sialon and mixed ?-ß sialon starting compositions were densified by either hot pressing or pressureless sintering using the oxides of Yb, Dy, Sm and Nd. The resulting materials were heat-treated at 1450°C for up ...
?ݧ Sialon Transformation in Calcium-containing ? -SiAlON Ceramics
(1999)
Recent studies on rare earth densified ?-sialon ceramics have shown that the resulting ?-sialon product, present either as a single phase or in conjunction with ß-sialon, is unstable when heat treated at lower (1350-1600°C) ...
