Abstract

As a result of the research carried out, conditions have been studied and created for the synthesis of spinel by using the sol-gel method. The kinetics of spinel phase formation has been studied. Received a fine ceramic powder, consisting of the main phase of spinel (MgAl2O4), which is obtained from waste and reactive magnesium oxide grade, having a particle size of 0.5 to 1 micron.
