Dense lanthanum silicate oxyapatite ceramics obtained by uniaxial pressing and slip casting

Comparison of Creep Behavior in Alumina Based Ceramics Densified by Spark Plasma Sintering and Hot Pressing

Spark plasma sintering (SPS) method, as plasma activated sintering, is a method applicable for rapid sintering of metals and ceramics. Owing to the advantage of rapid heating, the alumina ceramics obtained by SPS have a grain size and density comparable to those of hot pressed ones. The increase of densification rate may be related to some difference in ion transport characteristics. This study...

The effect of slip casting parameters on the ultrafine microstructure and density of pore-free YAG ceramic obtained by vacuum sintering

In this study, the effect of slip casting parameters on the ultrafine microstructure and the density of pore-free YAG ceramic was evaluated. A stable, high concentrated aqueous YAG slurry using Dolapix-CE64 as a dispersant was prepared. The effect of dispersant concentration as well as the solid load on the stability and rheological behavior of the slurry was also studied. The optimal dispersan...

Hot pressing of nanocrystalline TiO2 (anatase) ceramics with controlled microstructure

Pentacoordinate Silicon Complexes as Precursors to Silicate Glasses and Ceramics

The recent discovery that pentacoordinate alkali glycolato silicates such as monomeric MSi(OCH,CH,O),OCH,CH,OH or dimeric M,Si,(OCH,CH,O), (where M = Li, Na, K, or Cs) can be synthesized directly from SO,, ethylene glycol, and MOH suggests that these compounds may serve as useful, inexpensive precursors to alkali silicate glasses or ceramics, either by sol-gel processing or by simple pyrolysis....
