Zircon-free anorthite-based opaque glaze and preparation method thereof
The invention discloses a zircon-free anorthite-based opaque glaze, which comprises the following raw materials: 5-10 wt% of clay, 0-10 wt% of potassium feldspar, 20-40 wt% of albite, 5-20 wt% of quartz, 10-25 wt% of calcite, 0-10 wt% of wollastonite, 8-15 wt% of aluminum oxide, 1-10 wt% of zinc oxide, 3-8 wt% of calcined talc, 1-15 wt% of glass powder and 0.5-1.5 wt% of a nucleating agent. The invention also discloses a preparation method of the zircon-free anorthite-based opaque glaze. According to the invention, by using the low-cost raw materials and optimizing the formula system, flaky orblocky anorthite crystals are separated out from the interior of the glaze layer, and the three-dimensional crystallization is combined, so that the good glaze opacifying effect is achieved while thewhiteness and the hardness of the glaze are also improved, and the product performance is effectively improved; the raw materials do not contain radioactive elements and are harmless to the environment and human bodies; the opaque glaze is wide in application range and beneficial to popularization and application.
本发明公开了一种无锆钙长石基乳浊釉，其原料组成为：粘土5～10wt％、钾长石0～10wt％、钠长石20～40wt％、石英5～20wt％、方解石10～25wt％、硅灰石0～10wt％、氧化铝8～15wt％、氧化锌1～10wt％、烧滑石3～8wt％、玻璃粉1～15wt％、成核剂0.5～1.5wt％。此外，还公开了上述无锆钙长石基乳浊釉的制备方法。本发明通过使用成本低廉的原料并优化配方体系，使得釉层内部析出片状或块状钙长石晶体，并结合三维立体析晶，从而实现良好的釉面乳浊效果，同时也提高了釉面的白度、硬度，有效提高了产品性能。本发明原料不含有放射性元素，对环境和人体无害；而且乳浊釉的适用范围广，有利于推广和应用。
