High Translucent Dental Zirconia Blank and Sintered Body
A zirconia ceramic body for use with dental prosthetics has an L* value between 10 and 20 for a sample thickness 011 to 1.3 mm in accordance with CIE L*a*b* colorimetric system. The zirconia ceramic body can have between 6-20 wt % or 7.20 wt % of yttria based on total weight percent of the zirconia ceramic body. The zirconia ceramic body is subsequently finally sinterable to produce a translucent zirconia sintered body. In one aspect, the sintered body has a total light transmittance of at least 36% and less than 50% to light with a wavelength of 400 nm, and less than 55% to light with a wavelength of 600 nm, at a thickness of 0.6 mm, measured using a LAMBDA 35 UV/VIS Spectrophotometer manufactured by Perkin Elmer.
