Sintering kinetics of MgO-TiO2 systems

Abstract

Ceramic materials have been in use in many different areas of human wellbeing for a very long time. The most common way of obtaining this material is using the process of sintering. During mechanical activation inorganic materials are ground when the grain size reduced. The crystal structure distortis and also changes, leading some systems to a chemical reaction and formation of a new compound. In this work we explain the influence of mechanical activation on sintering kinetics in MgCO3-TiO2 systems. We noticed a temperature drop and time reduction needed for MgTiO3 sintering when the duration of mechanical activation was longer.
