Abstract
Powdered oxides to be processed into glass or ceramic products by suspension in organic vehicles, followed by gelling and drying the suspensions and sintering the oxides to unitary products, are pretreated prior to incorporation in the suspension with a ketal drying agent. The pretreatment removes adsorbed water and surface hydroxyl groups from the articles, improving their dispersion properties and the properties of the resulting suspensions.
