Origin of Cracking Phenomena Observed in Decomposition Reactions
Thermal decomposition, often referred to as calcination, is one of the important steps in ceramic processing. Decomposition reactions are of particular interest because they produce highly active solids of large surface areas1−3. But the high reactivity of fine powders is often limited by agglomeration and/or aggregation problems2,4. Furthermore large voids developed by cracking during the decomposition reaction can limit the densification of fine powders.
