  • International Classification:
    C03B 29/00
  • US Classification:
    156 8911, 156 99
  • Abstract:
    Two methods of extending the lifetime of yttrium oxide as a plasma chamber material are provided. One method comprises making a three-layer component of a plasma processing chamber by co-sintering a dual-layer green body where one layer comprises ceramic particles and a second layer comprises yttria particles. The two layers are in intimate contact during the sintering process. In a preferred embodiment, the three layer component comprises an outer layer of yttria, an intermediate layer of YAG, and a second outer layer of alumina. Optionally, the disks are pressed together during the sintering process. The resulting three-layer component is very low in porosity. Preferably, the porosity of any of the outer layer of yttria, the intermediate layer of YAG, and the second outer layer of alumina, is less than 3%. The second method comprises sealing an yttria plasma spray coated component by applying a liquid anaerobic sealant with a room temperature viscosity of less than 50 cP to the component by brushing the sealant on all yttria surfaces of the component, wet cleaning the component, curing the wet cleaned component for over 2 hours at a temperature of at least 150 C. in an N2 environment; and, applying a second sealant coat to the cured substrate by repeating the procedure used to apply the first coat.
