Method of preparing anhydrous boric acid-containing glass batch

摘要

A process is described for preparing anhydrous boric acid (ABA)-containing glass batch compositions suitable for the preparation of glass fibers in which the batch, prior to its introduction into the furnace, is pelletized by adding water in sufficient quantities to maintain an adequate balling action and thus provide pellets in a form such that preheating by direct contact with flue gases does not cause deterioration of the pellets.
