Preparation of Phase – Pure Nanocrystalline Anatase and Rutile TiO2 using Hydrolysis of TiCl4 in presence of surfactants
Abstract: Hydrolysis of TiCl4 was carried out in two different ways to prepare nano crystalline TiO2. In the first method the hydrolysis of TiCl4 was carried under high acidic conditions at low temperature. In the second method hydrolysis was carried out using (NH4)2SO4 as an additive. It can be seen that the hydrolysis of TiCl4 under high acidic conditions promotes the growth of rutile phase of TiO2, where as hydrolysis in …

A Novel Technique for Improved Recovery of Mg-Analysis of the Microstructure and Physical Properties
Abstract: Aluminium-Magnesium alloys are used widely in industrial applications as well as for the preparation of metal matrix composite because of their low density and high specific strength. Magnesium has a low boiling point and the recovery of magnesium is poor when it is added in pure form particularly as cheaply available turnings to the liquid metal. Magnesium is added to aluminium for increasing its wettability and thus helping in uniformly …
