This invention belongs to the field of architectural ceramic glaze technology, specifically relating to a high-wear-resistant and high-color-rendering jade-porcelain stone glaze, glaze surface, and preparation process. By combining nano-sized alumina-zirconia composite powder with a rationally proportioned ratio of high-alumina clay, calcined zinc, and other raw materials, and utilizing the dispersion strengthening effect and high transparency of the nano-sized composite powder, along with the synergistic effect of the various raw materials, a glaze surface with high wear resistance, high color rendering, a warm jade-like texture, and a distinct multi-layered porcelain feel is achieved. Simultaneously, the chemical stability of the glaze surface is improved, and glaze defects are reduced. The preparation process of this invention optimizes the glazing sequence and adds a constant-temperature pre-firing step, combined with reasonable ball milling and firing process parameters. Constant-temperature pre-firing allows the jade-porcelain stone glaze to initially set, avoiding glaze flow and mixing phenomena during subsequent glazing, further strengthening the multi-layered structure and texture of the glaze surface, and achieving the effect of improving the bonding strength between the glaze surface and the body, ensuring stable product performance.

This invention belongs to the field of building ceramics technology and discloses a wear-resistant glazed ceramic tile and its preparation method. First, N and / or Nb ions are implanted into the protective glaze layer of the glazed ceramic tile via ion implantation. This forms new highly wear-resistant substances or new bonds on the surface of the protective glaze layer, making the glaze network structure more compact and thus improving the wear resistance of the glaze. Then, the ion-implanted ceramic tile undergoes alkali metal molten salt surface treatment to fill the vacancy defects and interatomic gaps generated during ion implantation, further improving the glaze quality and wear resistance. Finally, the molten metal-treated ceramic tile is annealed to repair the crystal structure of the glaze layer, further reducing glaze defects and improving wear resistance. This invention allows for precise control of the ion implantation amount, maintaining the wear resistance of the glazed ceramic tile for a long time, achieving the highest wear resistance level of 5.
