Effects of Milling Liquid on the Reaction‐Bonded Aluminum Oxide Process
Tóm tắt
The reaction‐bonded aluminum oxide process begins with aluminum, Al2O3, and usually ZrO2 powders that have been attrition‐milled in an organic liquid. The attrition‐milled powder is then compacted and heat‐treated in air to produce polycrystalline, Al2O3‐based ceramics. Safety considerations have made it desirable for the milling liquid to be changed from acetone to a less‐flammable solvent. In this paper, mineral spirits, ethanol, and mineral spirits that contains 2 wt% stearic acid are presented as viable alternatives to acetone. The effects of changing the milling liquid on the reaction process and the properties of the final fired ceramic are investigated.
