Problems solved by technology

Modern crystalline glazes are widely used in ceramic vases, lamps, smoking sets, stationery and sculptured animals. They are perfectly matched. However, most of the current crystalline glaze products are display ceramic products. How to apply it to daily-use porcelain, especially daily tableware? has not been resolved, so it is necessary to improve this

Abstract

The present invention is medium and high temperature sintered coarse crystalline Fe-Ti glaze and its preparation process. The coarse crystalline Fe-Ti glaze has TiO2 as crystallizing agent, stable crystal form with CaO, Fe2O3 and TiO2, good crystallizing effect even at high temperature and greatly lowered glaze material cost. The glaze material is prepared with feldspar 45 weight portions, quartz 15-20 weight portions, calcite 12-18 weight portions, titanium dioxide 5-8 weight portions, talcum 2-5 weight portions, iron red 5-10 weight portions and kaolin 5-10 weight portions, and through ball milling the material, sieving, adding water into the glaze slurry to 40-49 Be deg, sieving the glaze slurry, applying to biscuit, and sintering at 1250-1350 deg.c in a kiln.

Description

Technical field: [0001] The invention belongs to a ceramic glaze and a manufacturing method thereof, in particular to a coarse crystalline glaze of iron-titanium system on the surface of daily ceramics and furnishing ceramics and a batching method thereof, and belongs to the technical field of inorganic material ceramic glazes, and is used for medium and high temperature once On the fired ceramic products, especially on white porcelain utensils for daily use, mushroom-shaped crystal flowers bloom yellow glaze. Background technique: [0002] Crystal glaze is a kind of artificial crystal flower glaze. It is a glaze that introduces crystallizing agent into the basic glaze, and controls the formation of crystals of various shapes in the glaze layer by firing. There are many types of crystal glazes, including high temperature crystal glaze and low temperature crystal glaze. According to its composition, it can be divided into zinc silicate crystal glaze, titanium silicate crystal glaz...
