| 成果简介 | NOVELTY - Invention can be used in making pigments for ceramic glazes. To obtain a red pigment based on cerium dioxide doped with praseodymium, a solution of a mixture of cerium nitrate hexahydrate and praseodymium hexahydrate nitrate, taken in ratio in terms of metals, mol: Ce+3:Pr+3=0.99–0.50:0.01–0.50, in 99.7% formic acid at a ratio in terms of metals, mol: (Ce+3+Pr+3):HCOOH=1:4, held at room temperature until spontaneous start of reaction. Obtained powder is annealed in air at temperature of 500–600 °C for 0.5–1 hours. USE - Ceramics. ADVANTAGE - Invention enables to obtain a red pigment in the form of praseodymium-doped cerium dioxide of the composition CexPr1−xO2, where 0,01≤x≤0,40, a wide range of shades using a simple and environmentally safe method. 1 cl, 3 dwg, 4 ex |
