Abstract

Y₂O₃ ceramics has various applications. Choosing raw powders and control of their properties is crucial for obtaining full transparency. In this research, the influence of the milling conditions of Y₂O₃ powders on the characteristic of vacuum-sintered ceramics was studied. The milling was performed at a rate of 80-300 rpm for 1-22 h. It was found that milling at 300 rpm for 1 h gives the most promising nano-sized Y₂O₃ powder. The highest transmittance among obtained samples is 78.3% (1100 nm).
