Development of ?-ß SiAlON ceramics from different Si 3N4 starting powders
(2009)
?-ß SiAlON ceramics were produced from different starting Si3N4 powders including P-Si3N4 and ?-Si3N4 powders and mixtures of these powders. Gas pressure sintering was used for sintering. After sintering, resultant fracture ...
A comparative study of SiAlON ceramics
(Elsevier Sci LTD, 2012)
Two different varieties of Si3N4 powders were used to prepare SiAlON ceramics. 100% beta-Si3N4 was used from refractory grade powders (B1) and another purer 98% alpha-Si3N4 (50A) powder was used to prepare the SiAlON ...
Spark plasma sintering of Co-WC cubic boron nitride composites
(Elsevier Science BV, 2009)
25 vol.% cubic boron nitride (cBN) added tungsten carbide (WC) powders containing 6 wt.% Co (WC-6Co) were densified by spark plasma sintering (SPS) technique under different experimental conditions and the effect of cBN ...
Sr2+-Mg2+-doped SiAlON ceramics
(Blackwell Publishing, 2006)
In the present work, multi-cation-doped (Sr2+-Mg2+) SiAlON ceramics were investigated. MgO and SrO were used in 100:0 and 50:50 molar ratios. The mixture was sintered at 1800 degrees and 1830 degrees C for 1 h in a gas ...
Experimental and finite element study of the thermal conductivity of alpha-SiAlON ceramics
(Blackwell Publishing, 2007)
The thermal conductivity of monolithic Y-Sm/alpha-SiAlON was evaluated using experimental data and finite element analysis. The thermal diffusivities of Y, Y-Dy, and Y-Ce/alpha-SiAlON ceramics were also investigated ...
Influence of SiC addition on tribological properties of SiAlON
(Elsevier Sci LTD, 2011)
The tribological properties of gas pressure sintered SiAlON and its composite with 18 wt% silicon carbide (SiC) against two different mating materials, i.e., alumina and SiAlON are evaluated. SiAlON and SiAlON-18%SiC ...
Role of organic additives on non-aqueous tape casting of SiAlON ceramics
(Elsevier Sci LTD, 2011)
Suspensions consisting of precursor alpha/beta SiAlON forming powders azeotropic solvent mixture of 60 MEK/40E dispersant binder, and plasticizer were optimized for tape casting by theological measurements and tape properties ...
Fabrication of functionally graded SiAlON ceramics by tape casting
(Blackwell Publishing, 2006)
Functionally graded SiAlON ceramics (FG-SiAlONs) were successfully prepared by the tape casting and lamination approach. Non-aqueous SiAlON slurries with five different alpha to beta-SiAlON ratios (85 alpha:15 beta, 70 ...
Effect of SiC addition on the thermal diffusivity of SiAlON ceramics
(Elsevier Sci LTD, 2017)
Despite the fact that thermal conductivity is a crucial parameter for SiAlON ceramics with respect to their suitability in various applications, including high-temperature structural components, wear parts, and cutting ...
Production and permeability of porous Si 3 N 4 ceramics produced by starch addition
(Taylor and Francis Ltd., 2013)
•We produce highly porous (up to 66%) Si 3 N 4 .•We enhance the permeability of Si 3 N 4 by using starch as pore former.•Increasing starch amount (?20vol.%) created large and bimodal pore channels and permeability values ...
