Abstract
The invention discloses a method for preparing zirconium iron pink pigment from electrically-melted zirconium oxide. The method comprises the following steps of: 1) reshaping crystal appearance, namely performing zirconium oxide crystal appearance spheroidization on the common electrically-melted zirconium oxide powder by using a special device, so that the appearance of the electrically-melted zirconium oxide tends to be close to a spherical state; 2) removing impurities, namely washing the product obtained in the step 1) with diluted acid until the content of the impurities such as aluminium oxide (Al2O3), ferric oxide (Fe2O3), silicon oxide (SiO2), phosphorus pentoxide (P2O5) and the like is less than 0.1 percent, and then drying; 3) controlling granularity, namely grinding the electrically-melted zirconium oxide with impurities removed and controlling the granularity of the electrically-melted zirconium oxide to be 0 to 5 mu m; and 4) preparing samples, namely weighing the electrically-melted zirconium oxide obtained in the step 3), zirconium iron pink and other raw materials, mixing the materials completely and uniformly, grinding the mixture finely, heating the mixture to calcine for 5 hours, preserving heat for 1 hour when the temperature is 1,000 to 1,100 DEG C, cooling, and taking out the product. By the method, influence of reaction impurities is removed; reaction activity is improved; and the zirconium iron pink pigment is prepared from the electrically-melted zirconium oxide instead of zirconium, so the production cost of the zirconium iron pink pigment is reduced.
Description
Technical field
The present invention relates to a kind of electric-melting zirconia and produce the method for zirconium-iron pink pigment.
Background technology
At present the ceramic pigment industry is seldom produced zirconium-iron pink pigment with electric-melting zirconia, mainly be the composition principle of zirconium-iron pink pigment to be different from other zirconiums be colorant such as praseodymium yellow and vanadium orchid etc., zirconium-iron pink pigment belongs to half coated colorant.And electric-melting zirconia composition and active aspect do not reach chemical zirconium requirement, aluminum oxide and titanium oxide impurity are little in content height, the reactive behavior of electric-melting zirconia, therefore can not produce zirconium-iron pink pigment by the instead of chemical zirconium, but chemical zirconium production cost height causes the production cost of zirconium-iron pink pigment higher.
Summary of the invention
The technical problem to be solved in the present invention provides the method that low, the active high electric-melting zirconia of a kind of foreign matter content is produced zirconium-iron pink pigment.
In order to solve the problems of the technologies described above, the technical solution adopted for the present invention to solve the technical problems is: provide a kind of electric-melting zirconia to produce the method for zirconium-iron pink pigment, may further comprise the steps:
1): brilliant looks change shape and handle: with common electric-melting zirconia powder, carry out the spheroidizing of zirconium white powder crystal looks by special device, make the pattern of electric-melting zirconia be tending towards the subglobular state;
2) remove impurity: the step 1) products therefrom is washed to impurity A l with diluted acid

5Content is washed the back oven dry respectively less than 0.1% (quality);
3) granularity control: to step 2) electric-melting zirconia of removing behind the impurity grinds, and the granularity of electric-melting zirconia is controlled between 0～5 μ m;
4) preparation sample: the electric-melting zirconia of weighing step 3) gained and other raw materials of zirconium iron pink, fully evenly mixed and levigate after, heating and calcining 5 hours, insulation is 1 hour when reaching 1000-1100 ℃, cooling cooling back taking-up.
Wherein, to step 2) electric-melting zirconia after the pickling carries out spectral measurement, foreign matter content continued electric-melting zirconia is carried out pickling greater than 0.1% o'clock, until foreign matter content each less than 0.06% (quality).
Wherein, described diluted acid is 1% (quality) dilute sulphuric acid or dilute hydrochloric acid.
Wherein, the control of step 3) granularity is ground by ball-grinding machine, and observes control by laser particle analyzer.
Wherein, the described holding temperature of step 4) is 1050 ℃.
The invention has the beneficial effects as follows that by removing the electric-melting zirconia that the control of impurity and granularity is produced, removed the reaction impurities influence, it is big to improve reactive behavior, can produce zirconium-iron pink pigment by the instead of chemical zirconium, reduced the production cost of zirconium-iron pink pigment.
