| 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 temperature of the wollastonite
body was much less than that of conventional steatite and other
low-loss ceramics. |
