Medium-wave infrared transparent zirconia ceramic material and preparation method thereof
The invention discloses a medium-wave infrared transparent zirconia ceramic material and a preparation method thereof. The chemical composition of the medium-wave infrared transparent zirconia ceramic material is x mol% ZrO2-y mol% Y2O3-M, x mol% and y mol% respectively represent the molar content of zirconia and yttrium oxide in the material, x + 2y = 100, 96 < = x < = 97, 1.5 < = y < = 2, M is a sintering aid, M = p wt% Al2O3 + q wt% SiO2, 0.01 < = p < = 0.05, 0.001 < = q < = 0.002. The stability of the tetragonal phase structure of the zirconia ceramic is synergistically regulated through the grain size and the yttrium content.
