发明名称 HIGH TOTAL TRANSMITTANCE ALUMINA DISCHARGE VESSELS HAVING SUBMICRON GRAIN SIZE
摘要 The present invention uses a post-sinter-HIP anneal to increase the total transmittance of ceramic discharge vessels comprised of a submicron-grained alumina doped wit h MgO. After the anneal, the submicron-grained alumina discharge vessels have high values of both total and in-line transmittance, and are thus suitable for use in focused- beam, short-arc lamps. In particular, the total transmittance of the discharge vessel is increased to greater than 92% in the wavelength range from about 400 nm to about 700 nm.
