Abstract

The invention discloses a frit used for producing Longquan celadon, a Longquan celadon frit glaze and a production method of the frit glaze. Raw materials of the frit comprise, by weight, 45-95% of rare earth tailings, 1-30% of Longquan porcelain clay, 1-25% of alumina powder, 1-15% of kaolin, 1-30% of yellow glaze soil, 0-25% of potash feldspar, 0-20% of quartz and 0-10% of talcum. The rare earth tailings are adopted as a main raw material of the frit, so the recycling of the rare earth tailings is realized, and the use amounts of other routine Longquan celadon raw materials are greatly reduced; and trace rare earth elements in the rare earth tailings have an obvious color development promoting effect on the celadon glaze, so extra addition of a coloring agent or a ceramic coloring chemical engineering raw material to the glaze is prevented, thereby the manufacturing cost of the Longquan celadon frit glaze is reduced, the color appearance of the glaze is stable, and industrial large-scale production is facilitated.

Description

technical field [0001] The invention relates to a Longquan celadon glaze, in particular to a frit for preparing Longquan celadon, a Longquan celadon frit glaze and a preparation method of the frit glaze. Background technique [0002] my country has rich reserves of rare earth ore resources, but due to the low grade of rare earth ores, rare earth ores will produce rare earth tailings after being extracted and utilized. At present, the treatment methods of rare earth tailings are mainly stacking or landfilling. This treatment method not only occupies a large area and wastes a lot of land resources; it also causes serious pollution to water and soil resources, destroys the ecological balance, and hinders the sustainable development of the economy. develop. Therefore, the resource reuse of rare earth tailings is an important way to realize the sustainable development of mineral resources. This is not only the strategic demand for the development of my country's rare earth indus...
