  • Publication number: 20240182373
    Abstract: The present invention discloses an antibacterial ceramic tile and a preparation method thereof. The method comprises applying an antibacterial protective glaze containing Ulan tea-quartz on the surface of a green body, and then firing to obtain an antibacterial ceramic tile. The mass percentage of Ulan tea-quartz to the antibacterial protective glaze is 35% to 45%. Controlling the mass percentage content of Ulan tea-quartz to the antibacterial protective glaze within the aforementioned range not only can achieve an excellent antibacterial property, but also avoids excessive glossiness, rough texture, or poor flatness of the ceramic glaze surface.

  • Publication number: 20240132407
    Abstract: The present invention relates to a ceramic slate with a colored jade effect and a preparation method comprising: pressing and forming raw materials containing a ceramic base material and colored glass fragments to obtain a ceramic green body; drying and firing the ceramic green body to give a ceramic slate with colored jade effect particles dispersed on the surface of the green body; wherein, the colored glass fragments account for 3 wt % to 5 wt % of the ceramic base material. Since colored glass waste instead of frits and pigments is used to prepare the ceramic slate with the colored jade effect, the ceramic slate does not have the phenomenon of pigment dispersion after high-temperature firing, and the surface of the fired ceramic slate shows a shape of micro-protrusion, so that the polished tile surface is smoother and free from pits, resulting in a better tile surface effect.

  • Patent number: 11761112
    Abstract: A method for preparing a large-size two-dimensional layered metal thiophosphate crystal includes the following steps: 1) weighing raw materials of indium spheres, phosphorous lumps and sulfur granules according to a predetermined amount and proportion, mixing them, and using iodine as a transport agent and potassium iodide as a molten salt; 2) adding the raw materials, the iodine and the potassium iodide to a reaction vessel together, and vacuum sealing it under a certain pressure, and then subjecting it to a high-temperature reaction; 3) taking out the products after the reaction, and washing the products to remove the residual iodine and potassium iodide and obtain large-size two-dimensional layered metal thiophosphate crystals. This method is simple and highly efficient.
