Preparation method of nanometer praseodymium yellow ceramic pigment
The invention relates to the technical field of a fine ceramic material, and particularly to a preparation method of a nanometer praseodymium yellow ceramic pigment. The preparation method comprises: taking sodium silicate, zirconium oxychloride, praseodymia, ammonium oxalate, ammonium chloride, hydrochloric acid, and the like as original raw materials; adopting a sol-gel method to prepare a praseodymium yellow gel precursor; taking sodium chloride and sodium fluoride as a mixed mineralizer; and preparing the nanometer praseodymium yellow ceramic pigment through low temperature sintering. The raw materials are low in price and are easily available; the production technology is simple and easy to control; the reagents are environment-friendly, so that the preparation method is convenient for industrial production. The prepared pigment has advantages of pure color, low sintering temperature, low energy consumption, loose and easy-powdered product, and the like, and is an ideal pigment for sintering a high-quality ceramic product.
