Enhanced Transformation and Sintering of Transitional Alumina Through Mechanical Seeding
Alumina is one of the most widely used ceramics, encompassing spark plugs, catalysts, heat sinks on computer chips, high temperature insulation, lighting envelopes and milling media. Because of this wide variety of applications, alumina is one of the most thoroughly studied ceramic materials. In particular, a significant amount of research has been performed since the 1950’s within the catalysis and ceramic fields with the goal of understanding and controlling such properties as surface acidity and basicity, surface area, crystallite size, agglomeration, thermal stability, phase transformation kinetics, and sinterability. This paper will focus on the phase transformations of alumina and show how the transformation kinetics can be increased to improve the sinterability of compacts prepared from the transitional alumina phases.
