[0033] The preparation method of praseodymium zirconium yellow ceramic pigment is as follows:
[0034] Step 1, pulverizing and grinding praseodymia, zirconia, silica airgel and mineralizer raw materials to a particle size of 1 μm, drying and mixing uniformly;
[0035] Step 2: Place the mixed raw materials in a sagger for calcination. The calcination temperature is 1000°C. The heating time is controlled at 3 hours. After the temperature rises to the calcination temperature, keep it warm for 2 hours. Take out the sagger to obtain the praseodymium-zirconium yellow ceramic pigment. burnt products;
[0036] Step 3: Grind the calcined product in Step 2 evenly, wash with deionized water for 3 times, and dry to obtain the required praseodymium-zirconium yellow ceramic pigment.
[0037] Judgment method of the color intensity of the pigment: Add 6% of the prepared praseodymium-zirconium yellow material to the transparent base glaze to make a colored glaze, and then glaze it on the blank ...

Abstract
The invention discloses a small-particle-diameter praseodymium zirconium yellow ceramic pigment which comprises the following components in percentage by weight: 3-6% of praseodymium oxide, 48-62% of zirconium oxide, 30-38% of silicon dioxide and 3-8% of a mineralizing agent, wherein the zirconium oxide selects the product which does not remove hafnium elements in the zirconium oxide production process, wherein the atom molar ratio of zirconium oxide to the hafnium elements is greater than 40:1; silicon dioxide selects silicon dioxide aerogel, wherein the BET specific surface area is 500-800 m<2> / g, the average particle diameter is 3-8 [mu]m, and the pore volume is 3-5. The praseodymium zirconium yellow pigment is small in particle diameter and relatively stable in structure, and is hard to damage in the ceramic ink preparation process. Meanwhile, the pigment is high in color strength in transparent glaze, and fine and smooth in color tone, and can be used as the high-grade ceramic pigment.
Description
technical field [0001] The invention relates to a ceramic color material, in particular to a praseodymium zirconium yellow ceramic color material with a small average particle size and a preparation method thereof, and a method for preparing ceramic ink by using the ceramic color material. Background technique [0002] Ceramic decoration inks are used in various ceramic decoration technologies, such as traditional ceramic printing technology, color inkjet printing technology for ceramic decoration (Ink Jet Printing), ceramic inkjet printing technology, etc. Generally speaking, the method for decorating ceramics is to print ceramic ink or colorant containing colorant on the cooked ceramic body by inkjet or other printing methods, and then fire to fix the pattern. Restricted by the nozzle aperture of the inkjet and the ink channel system, the colorant particles in the ceramic ink must be small enough to ensure smooth inkjet. At the same time, in order to avoid particle precip...
