متن کاملDevelopment of nano-grained Calcium Hy-droxyapatite using slip casting technique
The purpose of this study is to synthesize nano-grained Calcium Hydroxyapatite (HAp) through slip casting technique. For this, hydroxyapatite powders were synthesized using two methods, wet chemical method and Ammoniacal method. The as-prepared powders and calcined powders were characterized using XRD, FTIR, to study the phases of the powders. The hydroxyapatite powder calcined at 1000°C for 2h...
متن کاملSeparation of sillimanite from beach sands contaminated with shell
Sillimanite is a very important raw material for the manufacture of refractory bricks used in iron and steel, cement and glass industries. In some coastal stretches of south India, the beach sand is contaminated with shell. After recovering heavy minerals like ilmenite, rutile, zircon and garnet by various physical separation techniques, the final sand containing sillimanite, quartz and shell i...
متن کاملCompressibility and crystal structure of sillimanite, Al2SiO5, at high pressure
R.T. Downs Department of Geosciences, University of Arizona, Tucson, Arizona 85721, USA Abstract The unit-cell dimensions and crystal structure of sillimanite at various pressures up to 5.29 GPa have been refined from single-crystal X-ray diffraction data. As pressure increases, a and b decrease linearly, whereas c decreases nonlinearly with a slightly positive curvature. The axial compression ...
متن کاملThe 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...
