Wet vibro-grinding of zircon with surfactants

An investigation was carried out of the effect of various surfactants added during the wet vibrogrinding of zircon on the degree of dispersion of the powder and on the sintering of specimens molded from the powders. When added in proportions up to 0.2% all surfactants tested (naphthenate soap, Asidol, titanium soap, GKZh-94, GKZh-10, triethanolamine, and sugar) helped to reduce the time required to grind the zircon to a given fineness from 15–20 to 4 h, i.e., by a factor of about 2.5–4.
