Luminescence Properties of Terbium-, Cerium-, or Europium-Doped α-Sialon Materials
- van Jwh Joost Krevel, van Jwt Rutten, H. Mandal, H. Hintzen, R. Metselaar
- Chemistry
- 1 April 2002
New interesting luminescent α-sialon (M(m/val+)val+ Si12-(m+n) Al(m+n)OnN(16−n)) (M=Ca, Y) materials doped with Ce, Tb, or Eu have been prepared and their luminescence properties studied. These show… Expand
X-ray data for new Y-Si-Al-O-N glass ceramics
- K. Liddell, H. Mandal, D. Thompson
- Materials Science
- 1997
Abstract Since the 1970s an increasing number of crystalline oxynitrides have been observed as grain boundary phases in sialon ceramics. In particular, the well-known four- and five-component phases… Expand
Microstructure–permeability relation of porous β-Si3N4 ceramics

Al2O3 composites, comprising 10 wt% ZrO2 stabilized with 0.3 wt% MgO (MSZ/Al2O3) and 17.5–25 vol% cubic boron nitride (cBN)-added MSZ/Al2O3, were fabricated by spark plasma sintering technique, and… Expand
Subsolidus phase relationships in the system Dy2O3-Si3N4-AlN-Al2O3
- W. Sun, D. Yan, L. Gao, H. Mandal, D. Thompson
- Materials Science
- 1996
Abstract Subsolidus phase relationships in the system Dy-Si-Al-O-N have been determined. Forty-two compatibility tetrahedra were established in the region Dy 2 O 3 -Si 3 N 4 -AlN-Al 2 O 3 . Within… Expand

- S. Kurama, Mathias Herrmann, H. Mandal
- Materials Science
- 2002
Abstract A series of samples with yttrium α-SiAlON compositions and different amounts of additive has been fabricated from α-Si 3 N 4 , AlN, Al 2 O 3 and Y 2 O 3 starting powders, using gas pressure… Expand
Cytocompatibility property evaluation of gas pressure sintered SiAlON–SiC composites with L929 fibroblast cells and Saos-2 osteoblast-like cells
- A. Kumar, A. K. Mallik, +6 authors B. Basu
- Materials Science
- 1 April 2012
Although the oxide ceramics have widely been investigated for their biocompatibility, non-oxide ceramics, such as SiAlON and SiC are yet to be explored in detail. Lack of understanding of the… Expand
New developments in a-SiAlON ceramics
- H. Mandal
- Materials Science
- 1 October 1999
Abstract Two different α -sialon compositions have been densified by either pressureless sintering or capsul-free sinter HIPing using either single cation namely strontium, lanthanum, cerium,… Expand
Spark plasma sintering of TaC–HfC UHTC via disilicides sintering aids
