Features of Synthesis of Complex Oxide Systems by Means of SGA-Method
Journal Title: Фізика і хімія твердого тіла - Year 2014, Vol 15, Issue 1
Abstract
In this paper studies the mechanisms of complex oxide systems formation obtained by the method of sol-gel autocombustion. It was found that at the mixing of precursors hydrolysis reaction occurring, leading to the formation of a sol. Neutralization of the dispersion environment using 25 % aqueous ammonia solution to pH = 7 leads to intense formation of aggregates of particles. It is shown that the process of the dry gel autocombustion occurred the resulting exothermic reaction at a temperature of about 483 K.
