Abstract

The invention relates to the technical field of ceramic preparation, in particular to a method for preparing zinc silicate crystal glaze from granite. The zinc silicate crystal glaze comprises the following materials: granite, kaolin, quartz, limestone, glass powder, barium carbonate, emery powder, albite, talcum powder, a nucleating agent and a nucleating agent. The preparation method comprises the following steps: weighing the raw materials in parts by weight, mixing, adding water and aluminum balls, carrying out ball milling, sieving the glaze subjected to ball milling through a 130-150-mesh sieve, putting the sieved glaze and a green body into a mold, molding by adopting a dry pressing method, completing glazing and molding at the same time, drying in a drying chamber at 20-15 DEG C, and finally performing sintering to obtain the zinc silicate crystal glaze. The zinc silicate crystal glaze prepared by the method disclosed by the invention is good in mechanical strength, bright, colorful and dispersed in crystal flower, does not need manual operation, and adopts relatively low-price granite as a main raw material, so that the production cost is further reduced.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a method for preparing zinc silicate crystalline glaze from granite. Background technique [0002] Granite is a kind of tectonic rock formed by lava erupted from volcanic eruptions in a molten state under considerable pressure to the surface of the earth's crust. The magma does not eject out of the ground, but slowly cools and solidifies underground. Acidic igneous rocks are igneous rocks (igneous rocks). Granite is mainly composed of quartz, feldspar and mica, of which the content of feldspar is 40% to 60%, and the content of quartz is 20% to 40%. Its color depends on the type and quantity of the components contained. Granite is a rock with a fully crystalline structure. High-quality granite has fine and uniform crystal grains, compact structure, high quartz content, and bright feldspar luster. At the same time, it has a hard texture, good acid and alkali resistance...
