Hard and tough alpha-SiAlON ceramics
Mandal, Hasan; Hofmann, J. Michael (Trans Tech Publications LTD, 2000)Yb, Nd/Ca and Ce/Ca containing a-sialon starting compositions have been densified by either pressureless sintering or capsul free sinter/HIP'ing using "conventional" alpha-Si3N4 powder. X-ray diffraction studies of both ... -
Novel developments in alpha-SiAlON ceramics
Mandal, Hasan; Hofmann, J. Michael (Trans Tech Publications LTD, 2000)Densification and stabilization of alpha-sialon ceramics have been investigated by using oxides of large cations (Sr2+, La3+, Ce3+, Nd3+) and their equimolar mixtures with calcium or ytterbium as a principal cation. All ...
