Title:
TRANSLUCENT YTTRIUM OXIDE SINTERED COMPACT AND METHOD OF MANUFACTURING THE SAME
Document Type and Number:
Japanese Patent JP2007254186
Kind Code:
A
Abstract:
To obtain a translucent yttrium oxide sintered compact, wherein linear transmittance in visible wavelength ranging from 400 nm to 6 μm excluding a specific absorption wavelength is ≥70% when the thickness is 1 mm without controlling aluminum content to 5-100 wt.ppm expressed in terms of metal, silicon content to ≤10 wt.ppm expressed in terms of metal.
The translucent yttrium oxide sintered compact contains yttrium oxide as a main component, and hafnium, wherein the linear transmittance in visible wavelength ranging from 400 nm to 6 μm excluding the specific absorption wavelength is ≥70% when the thickness is 1 mm.
