Black matte glaze for sanitary ware, sanitary ware and preparation method of black matte glaze
The invention discloses black matte glaze for sanitary ware, the sanitary ware and a preparation method of the black matte glaze, and relates to the technical field of ceramics. The basic glaze comprises the following components: 8-15 parts of potassium feldspar, 25-36 parts of quartz powder, 1-2 parts of calcined zinc oxide, 12-15 parts of dolomite, 7-9 parts of wollastonite, 3-5 parts of kaolin for glaze, 1-3 parts of calcined alumina, 2-8 parts of barium carbonate, 4-7 parts of calcined talc and 10-17 parts of Jiangxi lithium chinastone; the cobalt-containing pigment is 6 to 11 parts. The components of the black matte glaze for the sanitary ware are beneficial to promoting crystal precipitation of calcium, magnesium and barium elements, and the situation that color development of cobalt-containing pigment is affected due to the high content of aluminum element can be avoided; jiangxi lithium chinastone is introduced, free quartz and quartz crystal phase separation are reduced, and anorthite and wollastonite crystals can be separated out easily; and the basic glaze can avoid the problem that the melting temperature of the glaze is reduced due to the introduction of cobalt-containing pigment, and avoids the phenomena that the glaze surface is cloudy, rough and dirt-absorbing.
本发明公开了一种卫生洁具用黑色哑光釉、卫生洁具及其制备方法，涉及陶瓷技术领域，包括基础釉和含钴色料；所述基础釉包括以下组分：8～15份钾长石、25～36份石英粉、1～2份煅烧氧化锌、12～15份白云石、7～9份硅灰石、3～5份釉用高岭土、1～3份煅烧氧化铝、2～8份碳酸钡、4～7份烧滑石和10～17份江西锂瓷石；所述含钴色料为6～11份。所述卫生洁具用黑色哑光釉的组分有利于促进钙、镁和钡元素的晶体析出，还能避免铝元素含量高而影响含钴色料发色；并引进江西锂瓷石，减少游离石英和石英晶相析出，有利于析出钙长石和硅灰石晶体；且基础釉能避免因引入含钴色料而导致釉料熔融温度降低的问题，避免釉面发蒙、粗糙和吸污的现象。
