Alcohol Interaction with Zirconia Powders

Description

<jats:p>The mechanism by which alcohol washing of ceramic powders produces “soft” agglomerates has been investigated by studying the interaction of ethanol with hydrous ZrO<jats:sub>2</jats:sub> powders using Fourier transform infrared (FTIR) spectroscopy. Unambiguous evidence of ethoxide formation has been found, which apparently prevents bond formation between adjacent particles and thus the formation of “hard” agglomerates.</jats:p>
