Matte glaze, super-flat fine glazed tile and preparation method of super-flat fine glazed tile

The invention relates to the technical field of architectural ceramics, in particular to a matte glaze, a super-flat fine glazed tile and a preparation method of the super-flat fine glazed tile. The matte glaze comprises the following raw material components in parts by weight: 57-89 parts of a glaze base material, 4-8 parts of aluminum oxide, 3-6 parts of silicon dioxide, 6-10 parts of a crystal nucleus forming agent and 8-10 parts of calcium phosphate, wherein the aluminum oxide is nanometer aluminum oxide, the silicon dioxide is nanometer silicon dioxide, and the crystal nucleus forming agent is zinc oxide and/or titanium dioxide. A glaze surface formed by the matte glaze is good in matte effect and uniform in gloss. 本发明涉及建筑陶瓷技术领域，具体涉及一种亚光釉料、超平细腻釉面砖及其制备方法。所述亚光釉料，以重量份计，包括如下原料组分：釉料基料57份~89份、氧化铝4份~8份、二氧化硅3份~6份、晶核形成剂6份~10份以及磷酸钙8份~10份；其中，所述氧化铝为纳米氧化铝，所述二氧化硅为纳米二氧化硅，所述晶核形成剂为氧化锌和/或二氧化钛。该亚光釉料形成的釉面亚光效果好，且光泽均匀。
