The multi-cation doped α/β-SiAlON composite ceramics tool materials were prepared via
spark plasma sintering. The effects of cation type (Yb, Sm, Yb/Sm), composition, and …

Abstract β-SiAlON powders were fabricated using Al, Si, α-Al 2 O 3 and trace Y 2 O 3
powders as starting materials in flowing nitrogen atmosphere. The effect of Y 2 O 3 on …

The properties of SiAlON ceramics are strongly affected by the composition and structure of
the intergranular phase, which are controlled by dopants, sintering conditions and starting …

Nitrogen‐rich Ca–α‐SiAlON ceramics with nominal compositions CaxSi12− 2xAl2xN16 and
0.2≤ x≤ 2.6, extending along the Si3N4–1/2Ca3N2: 3AlN tie line, were prepared from …

The densification behavior, phase transformation kinetics, and grain orientation of multi-
cation doped (Yb, Sm) α/β-SiAlON ceramic tool materials prepared via spark plasma …

Self‐propagating high‐temperature synthesis (SHS) was applied to synthesize α‐SiAlON
powders doped by RE (RE= Eu, Pr, Ce) and codoped by RE and yttrium. The results showed …

SiAlON ceramic tools exhibit unique performance superiority in the machining of nickel‐
based heat‐resistant superalloys (HRSA). Production cost is a critical obstacle for the wide …

A Dy-α-sialon with a composition of Dy0. 33Si9. 3Al2. 7O1. 7N14. 3 was prepared by hot
pressing at 1800° C with an intermediate dwelling at 1550° C or 1650° C during the …

Different ratios of Ce to Y were selected to stabilize (Ce, Y) α-sialon during self-propagating
high-temperature synthesis (SHS). The phase assemblages were then studied for both SHS …

The concentration and distribution of selected eight heavy metals in five stations from lower
stretches of the Hooghly estuary were studied to ascertain the level of anthropogenic …
