Abstract

The invention relates to a special zirconium oxychloride for a coated cadmium selenide red ceramic pigment and a preparation method thereof, belonging to preparation of zirconium compounds. The special zirconium oxychloride is prepared from industrial zirconium oxychloride by purification by recrystallization. The preparation method is characterized by comprising the following steps: (1) dissolving industrial zirconium oxychloride in a 6.5-6.8 mol / L purified hydrochloric acid water solution, and supplementing industrial zirconium oxychloride until the zirconium oxychloride concentration is 140-160 g / L on the basis of ZrO2; and (2) adding a nonionic surfactant as a dispersing agent into the crystalline solution. The invention provides a high-coating-rate favorable-high-temperature-stability special zirconium oxychloride for a coated cadmium selenide red ceramic pigment capable of ensuring pure color tone of the pigment and a preparation method thereof. The coating rate of the coated cadmium selenide red ceramic pigment prepared from the special zirconium oxychloride is up to 7.2%; and the coated cadmium selenide red ceramic pigment has pure color tone and excellent high-temperature stability, and can resist high temperature of 1150 DEG C above.

Description

Technical field [0001] The invention relates to a special zirconium oxychloride special for a coated selenium-cadmium red ceramic pigment and a preparation method thereof. Preparation of compounds belonging to zirconium. Background technique [0002] Ceramic products are low-cost, easy to clean, corrosion-resistant, non-fading, and have extremely wide practicability and beautiful artistic decoration effects. Since ancient times, it has been deeply loved by people. In a sense, people’s pursuit of the decorative effect of ceramic art is sometimes far higher than its practical function. [0003] Ceramic pigment is one of the important factors to improve the artistic decoration effect of ceramic products. Color is the most important appearance and decoration feature of ceramic pigments. Among them, red ceramic pigment is an indispensable variety, because the red is warm and bright, which highlights the vitality. Therefore, the pure and bright red ceramic pigments have always been a...
