Abstract:
A transparent sintered yttrium aluminum garnet ceramic material formed from a solid-state reaction of a mixture of yttrium oxide powder and aluminum oxide powder during sintering. The ceramic material preferably has an in-line transmission of greater than 75% so it may used to fabricate arc tubes for high intensity discharge lamps used in automotive headlamps.
