Slip casting and pressureless sintering of Ti3AlC2

PRESSURELESS SINTERING OF B4C-NANOTiB2 NANOCOMPOSITE BY ADDITION OF Fe AND Ni AS SINTERING AIDS

B4C and its composites with TiB2 as second phase continues to be extensively used as the preferred ceramic material in military applications as armor systems for absorbing and dissipating kinetic energy from high velocity projectiles. It also exhibits a high melting point (2427 °C), and high neutron absorption cross section. Pressureless sintering of the B 4C-nanoTiB2 nanocomposite using small ...

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...

Effect of LiYO2 on the synthesis and pressureless sintering of Y2SiO5

Densification Kinetics and Structural Evolution During Microwave and Pressureless Sintering of 15 nm Titanium Nitride Powder

Microwave sintering (MWS) of commercially available 15-nm-size nanocrystalline TiN powder was studied. Densification kinetics and grain growth mechanisms of nano-TiN were evaluated using non-isothermal heating up to 1500 °C with variable heating rates. A true nanocrystalline ceramic with ~80-nm-size grains and 94.5 % theoretical density was obtained via MWS consolidation at 1400 °C. At higher t...

Preparation and Evaluation of Porous ƒÀ - TCP Based Composites

The scaffolds composed of monolithic ƒÀ-TCP and ƒÀ-TCP/ƒ¿-TCP composites were fabricated by a low-loaded environmental processing. The pore introduction was attempted using starch, instead of polymer beads. The aqueous slurry of the mixture of ƒÀ-TCP and starch was prepared for an aqueous slip-casting. Problem on the heterogeneity distribution of the starch in aqueous slip-casting was solved by...
