A method of bonding two ceramic parts to each other includes the steps of preparing a water-based slurry from Al<SUB>2</SUB>O<SUB>3 </SUB>powder and Y(NO<SUB>3</SUB>)<SUB>3 </SUB>solution in amounts that yield a eutectic compound of Al<SUB>2</SUB>O<SUB>3 </SUB>and Y<SUB>2</SUB>O<SUB>3 </SUB>when heated, placing the slurry in liquid, solid or gaseous form in direct contact with two ceramic parts that are to be bonded to each other, and heating the slurry to a temperature that bonds the two ceramic parts to each other. The method is particularly useful to join two ceramic parts where one is comprised of polycrystalline alumina and the other is comprised of one of single crystal alumina and polycrystalline alumina, such as an arc discharge vessel for a high intensity discharge lamp.
