Description

White opaque glaze, white opaque glaze ceramic and preparation method thereof
Technical field
The present invention relates to ceramic fields, and in particular to white opaque glaze, white opaque glaze ceramic and its preparation Method.
Background technique
Opaque glaze is a kind of method of common ceramic decoration, is widely used.Opaque glaze, that is, White-opalescent bright glaze.It It is due to, there is the 2nd small phase of, volume different from host glass phase refractive index or the 3rd phase substance, working as light in glaze glass When passing through glaze layer, milkiness particle makes light generate scattering process to cause the lighttight phenomenon of glaze layer.
According to the coherent condition of milkiness particle, opaque glaze can be divided into 3 classes: first is that there are a certain number of micro- in host glass Small crystals, referred to as crystal phase opaque glaze；Second is that liquid-liquid split-phase occurs in cooling procedure for glaze melt, isolated in host glass The higher 2nd phase glass of the small dispersion degree of volume, referred to as split-phase opaque glaze；Third is that being existed below in glaze surface layer of glass a large amount of micro- Minute bubbles, referred to as gas phase opaque glaze.Wherein crystal phase opaque glaze is divided into 2 kinds of crystal grain opaque glaze of original grain opaque glaze and precipitation again. The former is the milkiness that glaze is realized by additional infusibility substance, most common to have the turbid glaze of zirconium；The latter is in sintering process from glaze glass Spontaneous precipitation milkiness particle causes milkiness in glass.
Ceramic is one of most common utensil in people's daily life, and ceramic development history is the one of Chinese civilization history A important component part, wherein the invention and development of ceramics have more unique meaning, with the development of modern science technology, Occur many new ceramic kinds again in the last hundred years, they do not use or be rarely employed the tradition pottery such as clay, feldspar, quartz Porcelain raw material, but other special materials are used, or even be expanded to non-silicate, the range of non-oxidized substance, and there is many New technique makes ceramics be provided with various specific functions.
Coloring, glazing are a kind of effective means for increasing ceramic texture and aesthetic feeling on the surface of ceramic, and And the artistic effect that each glaze colours or pattern rise is different, have currently on the market various glaze colours, pattern or Its combination of person.Glaze various types in the market, such as opaque glaze, but there is also some problems: glaze opaque effect is not good enough, Whiteness is not high enough, and appearance is not exquisite enough；The wear-resisting property of glaze is poor and hardness is lower.
