High-whiteness frit opaque glaze containing zirconium oxide or coexistence of zirconium oxide and zirconium silicate and preparation method of high-whiteness frit opaque glaze
The invention discloses a high-whiteness frit opaque glaze containing zirconium oxide or coexistence of zirconium oxide and zirconium silicate and a preparation method of the high-whiteness frit opaque glaze. The high-whiteness frit opaque glaze comprises the following raw materials: 2-11 wt% of clay, 10-30 wt% of potassium feldspar, 5-30 wt% of quartz, 1-5 wt% of zinc oxide, 1-5 wt% of calcined talc, 10-20 wt% of calcium carbonate, 2-8 wt% of glass powder, 2-8 wt% of zirconium silicate and 3-12 wt% of a phase splitting agent. And the phase splitting agent is one or a combination of P2O5, TiO2 and B2O3. According to the invention, one or more phase splitting agents P2O5/TiO2/B2O3 are introduced into the glaze to form a phase separation area, so that zirconia is promoted to crystallize and is inhibited from being converted into zirconium silicate at the same time, finally, the low-zirconium high-whiteness opaque glaze containing zirconia or containing zirconia and zirconium silicate is obtained, and the purposes of saving cost, reducing the radioactivity of the glaze and improving the performance of the glaze surface are achieved.
本发明公开了一种含氧化锆或氧化锆和硅酸锆共存的高白熔块乳浊釉及其制备方法，高白熔块乳浊釉的原料组成为：粘土2～11wt％、钾长石10～30wt％、石英5～30wt％、氧化锌1～5wt％、烧滑石1～5wt％、碳酸钙10～20wt％、玻璃粉2～8wt％、硅酸锆2～8wt％、分相剂3～12wt％；所述分相剂为P2O5、TiO2、B2O3中的一种或其组合。本发明通过在釉中引入一种或多种分相剂P2O5/TiO2/B2O3以形成相分离区域，从而促进氧化锆析晶的同时抑制其向硅酸锆的转化，最终获得了含氧化锆或氧化锆和硅酸锆共存的低锆高白乳浊釉，实现了节省成本、减少釉料的放射性、提高釉面性能的目的。
