Metal glaze slip for iron-containing phosphate ceramic and preparation method of metal glaze slip
The preparation method comprises the following steps: adding an iron source solution and a phosphorus source solution into a reaction kettle, and carrying out high-energy instantaneous mixing reaction, so that materials instantaneously reach a molecular level and are fully mixed; strong shearing, friction, impact and collision among materials are generated in the reaction, primary particle cutting is conducted on the precursor through friction, and the nanoscale high-tap-density iron phosphate is prepared; filtering and washing: filtering and washing the iron phosphate slurry by using equipment, and finally preparing a filter cake of which the solid content is within a certain range; and high-speed homogeneous mixing: carrying out high-speed homogeneous mixing on the filter cake and slurry of other formulas to prepare high-tap-density glaze slurry with moderate fineness, and directly glazing and sintering without sieving. The prepared glaze slip is uniformly mixed at a molecular level, internal primary particles are tightly stacked, and air holes generated after mixing and sintering are greatly reduced, so that the probability that bubbles and pinholes appear on a glaze surface after glazing is reduced.
本发明公开了一种含铁磷酸盐陶瓷用金属釉浆及其制备方法，包括以下步骤：将铁源溶液和磷源溶液加入反应釜中进行高能瞬时混合反应，使物料瞬时达到分子层面充分混合，反应产生强烈剪切、摩擦、撞击以及物料间的碰撞、摩擦对前躯体进行一次颗粒剪裁，制备出纳米级高振实铁磷酸盐；过滤和洗涤：利用设备对铁磷酸盐料浆进行过滤和洗涤，最终制成固含量在一定范围内的滤饼；高速均质混合：将滤饼与其他配方的料浆进行高速均质混合，可制备出细度适中高振实釉浆，无须过筛直接施釉、烧结。制得的釉浆达到分子级别的均匀混合，内部一次颗粒堆积紧密，混合和烧结后产生的气孔将大大减少，从而降低施釉后釉面出现气泡和针孔的概率。
