Low-loss ceramics from wollastonite

Abstract

Low-loss ceramics of L-6 or better grade have been developed using indigenous wollastonite. The composition consisted mainly of wollastonite, clay and a flux. It was observed that a combination of several heavy metal modifiers such as Pb, Ba, etc gave a better result when incorporated in the flux. The maturing tempeiature of the wollastonite body was much less than that of conventional steatite and other low-loss ceramics. © 1984 Taylor & Francis Group, LLC.
