摘要：
Synthesis process of praseodymium - doped zta nanoceramics for application in health. biology, chemistry, laser, optical and luminescent devices, electronics and the ceramic industry. The present invention relates to conventionally sintered and co2 laser colored zta nanoceramics containing from 10-60%, preferably from 20-30% by weight of partially stabilized zirconia with 0.05-2 mol%, preferably 0.07 mol% of praseodymium oxides, which also served as "inorganic pigments of these materials". Pigmenting agents include praseodymium oxides (pr02, pr203 and pr6011). the addition of 0.05-2 mol% of praseodymium oxides pr02, pr203 and pr6011 to zirconia provides partially stabilized zirconia (psz) nanostructured yellow pigments with an average particle size of 34 ± 2 nm which are stable at high temperatures with at most 100% by volume in the tetragonal form and preferably 80% by volume in the tetragonal form and with a well distributed uniform and homogeneous yellow color that are environmentally friendly. These pigments are especially suitable for coloring zta nanoceramics for applications in the fields of dentistry, medicine, chemistry, biology, laser, optical and luminescent devices, electronics, fuels, cosmetics and the ceramic industry. The co2 laser sintering process allowed the production of highly dense zta colored nanoceramics (95.75-98.63 ± 0.01%), bulk density (4.28-4.31 ± 0.01 g / cm3), apparent porosity (1.15-5.19%) , vickers hardness (14.78-18.11 ± 0.30 mpa), fracture toughness (6.43-6.90 ± 0.05 mpa.m 112) and with high resistance to chemical and mechanical wear and suitable for application in the fields of dentistry, medicine, chemistry , biology, laser, optical and luminescent devices, electronics, fuels and the ceramic industry.processo de sintetização de nanocerâmicas zta dopadas com praseodímia para aplicação nas áreas da saúde, da . biologia, da química, de laser, de dispositivos ópticos e luminescentes, eletrônica e na indústria cerâmica. a presente inve
