[Alumina reinforced porcelain jacket crown].
Aluminum oxides provide one of the most useful sources of high-strength and high-modulus crystals. New types of high alumina content glasses may replace feldspathic porcelains. Esthetics compare favorably.
ALUMINA IN WHITEWARE
A brief resume on an extensive investigation of the use of calcined alumina in white-ware bodies is presented. Its use in vitreous chinaware, semivitreous dinnerware, electrical porcelain, cooking ware, and sanitary ware is discussed. Data are given also on special alumina bodies of unusual strength.
Direct conversion pulsed UWB transceiver architecture
Ultra-wideband (UWB) communication is an emerging wireless technology that promises high data rates over short distances and precise locationing. The large available bandwidth and the constraint of a maximum power spectral density drives a unique set of system challenges. This paper addresses these challenges using two UWB transceivers and a discrete prototype platform.
