Wear-resistant and corrosion-resistant ceramic glaze as well as preparation method and application thereof
The invention relates to wear-resistant and corrosion-resistant ceramic glaze as well as a preparation method and application thereof, and belongs to the technical field of ceramic preparation. The preparation method comprises the following steps: firstly, melting bauxite, quartz sand and aluminum dihydrogen phosphate at high temperature to obtain a first melt, quenching, drying and crushing to obtain first frit powder, melting kaolin and calcium carbonate at high temperature to obtain a second melt, quenching, drying and crushing to obtain second frit powder; and carrying out ball milling on the first frit powder, the second frit powder, clay, titanium dioxide powder, zirconium dioxide powder and water to obtain the wear-resistant and corrosion-resistant ceramic glaze. According to the invention, a first frit is in a glassy state containing an Al2O3-SiO2 binary system and an Al2O3-P2O5 binary system, and the Al2O3-SiO2 binary system is located in a crystallization region of mullite; the second frit is in a glassy state of a CaO-Al2O3-SiO2 ternary system, and is positioned in a crystallization region of the anorthite; a wear-resistant and corrosion-resistant glaze surface is formed by in-situ precipitation of mullite crystals, anorthite crystals and an aluminum phosphate film.
本发明涉及一种耐磨耐蚀陶瓷釉料及其制备方法和应用，属于陶瓷制备技术领域。首先将铝矾土、石英砂、磷酸二氢铝高温熔融得到第一熔体，淬冷后烘干粉碎得到第一熔块粉，将高岭土和碳酸钙高温熔融得到第二熔体，淬冷后烘干粉碎得到第二熔块粉，然后将第一熔块粉、第二熔块粉、粘土、二氧化钛粉末、二氧化锆粉末和水球磨得到耐磨耐蚀陶瓷釉料。本发明第一熔块为包含Al2O3‑SiO2二元体系和Al2O3‑P2O5二元体系的玻璃态，且Al2O3‑SiO2二元体系位于莫来石的析晶区域；第二熔块为CaO‑Al2O3‑SiO2三元体系的玻璃态，且位于钙长石的析晶区域；通过原位析出莫来石晶体、钙长石晶体和磷酸铝薄膜形成耐磨耐蚀釉面。
