[ 1 ] - Preparation of Porous and Dense Bulk Samples in Calcium Magnesium Silicate Systems using Steel Slag and Different Additive by Conventional Sintering Method (TECHNICAL NOTE)

In order to obtain the bulk brick like samples, the mixture of steel slag, and sintering aid additive (like dolomite, glass, perlite, borax and phosphate sodium) were sintered at 1100°C for 2 minute. The flat and bloated surface appearances were obtained. The bulk densities of final sintered composites were from 1.3 to 2.41 g/cm3 and total porosities were from 15 to 40%. The bending strengths v...

[ 2 ] - UV-Vis Absorption and Luminescence Spectrum of LAS: Tb3+/Gd3 as a Laser Material (TECHNICAL NOTE)

This article discusses details study on crystallization , optical properties of Li-Al-Si-La glass containing nanocrystalline LaF3.and their optical energy gaps. The Urbach energy of glass samples was evaluated. By using (2% mole) Tb the green–blue range emission occurred, while by accumulation 1% mole Gd beside Tb, the indigo emission intensity (418 to 441 nm) increased.
