Lead-free silver metal glaze and preparation method of lead-free silver metal glaze product
The invention discloses a lead-free silver metal glaze suitable for one-time rapid firing of a roller kiln. The glaze comprises the following components in percentage by weight: 30-50% of potassium feldspar, 5-10% of talc, 5-10% of calcite, 20-30% of calcium phosphate, 10-25% of ferric oxide, 3-8% of kaolin and 5-15% of frit powder, and the frit powder comprises the following components in percentage by weight: 10-20% of calcium phosphate, 10-20% of aluminum phosphate, 20-50% of sodium borate, 10-15% of quartz and 5-10% of lithium oxide. The boron-phosphorus equal phase-splitting accelerant is introduced to promote the formation and growth of metal split phases, and a large amount of silver metal split phases are generated in a short time to obtain a metal effect.
本发明公开了一种适合辊道窑一次快速烧成的无铅银色金属釉料。釉料组成成分按重量百分比计其组成如下：钾长石30～50％，滑石5～10％，方解石5～10％，磷酸钙20～30％，氧化铁10～25％，高岭土3～8％，熔块粉5～15％，所述熔块粉的组成按如下重量百分比计组成如下：磷酸钙10～20％，磷酸铝10～20％，硼酸钠20～50％，石英10～15％，氧化锂5～10％。本发明通过引入硼磷等分相促进剂促进金属分相的形成和增长，短时间内大量产生银色金属分相获得金属效果。
