Electric porcelain ash glaze material, electric porcelain ash glaze and preparation thereof
The invention discloses an electric porcelain ash glaze material, an electric porcelain ash glaze and preparation thereof, wherein the electric porcelain grey glaze material is prepared from the following components in percentage by mass: 25%-27% of quartz; 36%-39% of feldspar; 8%-10% of talcum powder; 6-8% of limestone; 2%-4% of aluminum oxide; 2%-4% of Zuoyun powder; 5%-7% of zirconium silicate;2%-4% of spodumene; 1.5%-3% of barium carbonate; 0.2%-0.4% of a pigment; less than 0.2% of cobalt oxide; less than 0.5% of dispersing agent A15; and less than 1% of hydroxymethyl cellulose (CMC). When the ash glaze is prepared, the water content of glaze slip is controlled to be 34-36%, the viscosity is controlled to be 20-30 Pa.s, meanwhile, and the proportion of the ash glaze with the granularity smaller than 10 microns is (73-75)%; and the technical problems of glaze pinholes, glaze shrinkage and glaze high-temperature flow spreading are solved.
本发明公开了一种电瓷灰釉釉料、电瓷灰釉及其制备。其中电瓷灰釉釉料包括以下质量百分比的组分：石英25％‑27％；长石36％‑39％；滑石粉：8％‑10％；石灰石6‑8％；氧化铝2％‑4％；左云粉2％‑4％；硅酸锆5％‑7％；锂灰石2％‑4％；碳酸钡1.5％‑3％；色素0.2％‑0.4％；氧化钴小于0.2％；分散剂A15小于0.5％；羟甲基纤维素(CMC)小于1％。本发明在制备灰釉时控制釉浆的水分为34‑36％，粘度为20‑30Pa·s，同时颗粒度＜10μm，占比(73‑75)％；解决了釉面针孔、缩釉和釉子高温流展的技术问题。
