A method of manufacturing a transparent translucent yttria excellent in thermal shock characteristics and a translucent yttria sintered component

摘要

Preparing yttria (Y ₂ O ₃ ) powder having a particle size of 0.05 μm to 1 μm; Pre-sintering the compact formed from the powder; And the step of hot isostatic pressing (Hot Isostatic Pressing) the plastically sintered molded body; discloses a method for producing a light-transmitting yttria comprising. By manufacturing a light-transmitting yttria having high strength and thermal conductivity, an optical component having excellent thermal shock resistance characteristics while being transparent can be manufactured.
