The present study focuses on critical factors limiting single-phase formation of Ba2Ti9O20 (2:9). Apart from 2:9, other polytitanates that are richer in Ti or Ba could also be prepared as single-phase material without any stabilizing agent through ch

Alumina and zirconia were dispersed individually in aqueous media using Darvan C as the dispersant and at optimised pH condition. Based on sedimentation, rheology, yield stress, electrodeposition and zeta potential measurements, 2 wt-% of the dispers

Dispersion behaviour of SiC in aqueous media was studied using four different dispersants and as a function of pH. The slurry was characterized in each case by sedimentation, viscosity and rheological studies. The best dispersant was selected and its

Polytitanates in the TiO 2 -rich side of the phase diagram of BaO–TiO 2 system play a major role as microwave dielectric ceramics. The present study aims at synthesis of polytitanates through carbonate-gel route and to re-look at the formation mech

Different solvent systems in combination with three different dispersants were tried to find out the suitable solvent-dispersant combination, which give optimum dispersion of PSZ. Based on sedimentation, viscosity and rheology characteristics, zeotro

Compositions in the PNN-PMW-PT system can be tailored to give high dielectric constant for MLC applications. Low temperature firing of MLC is always advantageous in using the less expensive electrode systems. Controlled addition of LiNO3 reduces the
