Abstract
The invention relates to a novel cadmium-free red ceramic paint color, which belongs to the technology field of decorative ceramic materials and the ingredient mol percentage are as follows: 75-98 per cent CeO2, 1-15 per cent Pr6O11 and 1-10 per cent rare earth oxide and the weight percentage of mineralization agent is 2-5 per cent, wherein the rare earth oxide are one of Nd2O3, La2O3, Er2O3 and Sm2O3 and the mineralization agents are two or three of CaF2, NaF, KF, LiF, MgF2 and BaF2 mixing at any proportion. The paint color is used to producing cadmium-free red ceramic paint, which is good in color and has a using temperature of 800-1200 DEG C, which can meet the requirements of high temperature using.
Description
Technical field
The present invention relates to a kind of novel cadmium-free red ceramic pigment color agent, belong to the ceramic decoration material technical field.
Background technology
For a long time, cadmium pigment is widely used because of having bright-coloured red as fire color, still, contain cadmium pigment and in production and use, all can cause severe contamination environment, health to people is brought serious harm, and therefore, the substitution studies that contains cadmium pigment has caused the extensive attention of various countries.The Rhodia company of France has successfully developed rare-earth sulfide red pigment, tone and cadmium are that red pigment is very approaching, be used for coating at present, be that cadmium is the favorable substitutes of red pigment, be expected in products such as plastics, rubber, printing ink, be used, but the heatproof of rare-earth sulfide red pigment is low, has only 350 ℃, under oxidizing atmosphere, easily decompose, can't in beramic color, be applied.The substitution studies of cadmium red pigment is considered to a great problem for a long time in the beramic color, and the progress of this aspect is slow.
Summary of the invention
The object of the present invention is to provide a kind of novel cadmium-free red ceramic pigment color agent, be used to prepare cadmium-free red ceramic pigment color.
Novel cadmium-free red ceramic pigment color agent of the present invention, its batching mole number percentage composition is:
CeO
