The invention discloses a method for preparing a nanospherical ferrosilicon red-coated pigment by a microwave hydrothermal method, wherein the method comprises: firstly measuring a certain amount of deionized water into a beaker, adding iron chloride, enabling the iron chloride to be completely dissolved, adding borax into the solution of the previous step, and continuously stirring for 10min; dropping ethyl orthosilicate into the previous solution, then dropping 3mol / L of NaOH solution to regulate a pH value to a needed value, setting the temperature of a magnetic stirrer to be 40 DEG C, and continuously stirring for 120min; and moving the obtained mixed solution into a microwave hydrothermal reaction vessel for reaction at 180-210 DEG C, collecting the products after reaction, washing the products with deionized water until being neutral, and drying with a drying box to prepared the ferrosilicon red-coated pigment with 30-80nm of diameters and pure color. The method has prominent advantages of low preparation temperature, simple technology, and cheap and easily available raw material, so the method has a wide market prospect.

The invention relates to high-temperature bright-red printing glaze, its preparation method and a preparation method of a glazed tile. On the basis of not making big changes on a present glazed tile production technology, emphasis is put on adjustment and optimization of composition of printing basic glaze powder, composition of frit in the printing basic glaze powder, optimization and ratio of frits with different properties, composition of stamp-pad ink, processing technology of printing glaze, engraving mode of a rubber covered roller, mesh number of a screen printing plate and the like. Thus, the color of the surface of a high-temperature sintered glazed tile imprinted with the single printing glaze is bright, pure, glossy and shiny and is typical bright red. When the printing glaze is alternately printed with a printing glaze of other colors, the color on the surface is bright, pure, wide in color gamut and colorful, can be compared favorably with colors in the fields of fabrics, wallpaper, advertisement design, and has strong decorative effect and aesthetic feeling. Meanwhile, the technology has high universality and is easy to popularize in the industry.

The invention discloses a method for preparing a zirconium silicate coated carbon nanosphere ceramic black pigment. The method is characterized in that carbon nanospheres prepared from a biomass raw material by a hydrothermal method replace a traditional carbon source, the hydrophilicity is improved by use of rich oxygen-containing functional groups on the surfaces of the carbon nanospheres and the negative potential state, and the dispersity of the carbon source is enhanced; the thickness of wrappers of the carbon nanospheres and the electrostatic adsorption capability are adjusted and controlled to enable a zirconium silicate precursor to tightly wrap the carbon nanospheres; and under the action of a mineralizer, the ceramic black pigment in which zirconium silicate wraps the carbon nanospheres is prepared after high-temperature calcination. In the experiment process, through optimization and control of such conditions as the addition of glucose, the hydrothermal temperature, the hydrothermal time, the silicon-zirconium ratio, the stirring time of the precursor, type and consumption selection of the mineralizer and a firing system, the synthesized black pigment is pure in color, uniform in particle size and stable in performance, can be used in various high-temperature ceramic glazes, and has a high economical value.

The invention discloses a polychrome painting pigment prepared by taking red mudstone as a coloring agent. The polychrome painting pigment is characterized by comprising the following steps: roughly smashing and sieving the red mudstone; performing chemical ball milling by using mechanical force, and mixing with ceramic flux ingredients; adding water, stirring uniformly, coloring and roasting to obtain the product, wherein the roasting temperature is 780-850 DEG C. The polychrome painting pigment with excellent color generation is prepared by taking cheap red mudstone as a major raw material in combination with a mechanical force chemical ball milling method. Compared with a conventional preparation method of the polychrome painting pigment, the preparation method has the advantages of simple and convenient process, no environmental pollution, high yield, low energy consumption, low cost and pure color, thereby achieving a wide market prospect.
