Abstract
The invention discloses opacified glaze containing lithium oxide. The opacified glaze containing the lithium oxide is prepared from the following components in part by weight: 5 to 10 parts of zircon sand, 3 to 8 parts of lithium oxide, 5 to 10 parts of boric acid, 10 to 20 parts of potash feldspar, 2 to 5 parts of potassium nitrate, 4 to 10 parts of dolomite, 8 to 15 parts of ground limestone, 6 to 15 parts of kaolin, and 30 to 40 parts of quartz. According to a formula, the lithium oxide is adopted by the opacified glaze containing the lithium oxide, so the firing temperature can be reduced, energy sources can be saved, and furnace life is prolonged; melt viscosity is reduced, high-temperature flowability and vitrification degree are improved, pollution resistance capacity is improved, and the intensity and smoothness and flatness of a glaze surface are improved; the coefficient of thermal expansion is reduced, the defect of crack on the glaze surface is overcome, and thermal stability is improved; whiteness and glossiness are improved; and the chemical stability and acid resistance are improved.
Description
Technical field
The present invention relates to a kind of opaque glaze, particularly a kind of opaque glaze that contains Lithium Oxide 98min.
Background technology
Opaque glaze is a kind of method of common ceramic decoration, is widely used.Opaque glaze is the White-opalescent bright glaze; It is since exist in the glaze glass different with host glass phase specific refractory power, volume is small the 2nd mutually or the 3rd phase material, thereby when light during through the glaze layer milkiness particle make light produce scattering process to cause the lighttight phenomenon of glaze layer.
Can be divided into 3 types according to milkiness aggregation of particles state opaque glaze: the one, there is the small crystal of some amount in the host glass, be called the crystalline phase opaque glaze; The 2nd, liquid-liquid phase-splitting takes place in the glaze melt in process of cooling, in host glass, isolates the 2nd higher phase glass of the small dispersity of volume, is called the phase-splitting opaque glaze; The 3rd, below the glaze surface layer of glass, there are a large amount of micro-bubbles, be called the gas phase opaque glaze, wherein the crystalline phase opaque glaze is divided into the original grain opaque glaze again and separates out 2 kinds of crystal grain opaque glazes.The former be through add the infusibility material realize the milkiness of glaze the most frequently used the turbid glaze of zirconium arranged; The latter be in sintering process from glaze glass the spontaneous milkiness particle of separating out cause milkiness.At present, opaque glaze widespread use in ceramic industry.Opaque glaze can hide the color and some defective of base substrate, enriches the glaze of ceramic product and decorates, and simultaneously, makes a large amount of inferior raw materials or industrial residue can be used as base and uses raw material.
This has not only reduced production cost in higher-grade raw material exhausted day by day today, resource is used adequately reasonably, and can increases the assortment of product, improves product specification, has therefore received liking of people.In recent years, along with science and technology development, no matter opaque glaze was in research or in application facet; Many breakthroughs are all arranged; Be widely used at present the decoration of sanitary china, architectural pottery and domestic ceramics, make ceramic surface colorful, change all the time, represent personalization.
Summary of the invention
The object of the invention is to provide a kind of opaque glaze that contains Lithium Oxide 98min.
For addressing the above problem; The technical scheme that the present invention adopted is: a kind of opaque glaze that contains Lithium Oxide 98min, process by the component of following parts by weight: 5 ~ 10 parts of zircon sands, 3 ~ 8 parts of Lithium Oxide 98mins, 5 ~ 10 parts of boric acid, 10 ~ 20 parts of potassium felspar sands, 2 ~ 5 parts in saltpetre, 4 ~ 10 parts of rhombspars, 8 ~ 15 parts of water-ground limestones, 6 ~ 15 parts of kaolin, 30 ~ 40 parts in quartz.
The said opaque glaze that contains Lithium Oxide 98min is processed by the component of following parts by weight: 5 ~ 8 parts of zircon sands, Lithium Oxide 98min 3-7 part, 5 ~ 7 parts of boric acid, 12 ~ 18 parts of potassium felspar sands, 3 ~ 4 parts in saltpetre, 4 ~ 8 parts of rhombspars, 8 ~ 12 parts of water-ground limestones, 6 ~ 12 parts of kaolin, 30 ~ 35 parts in quartz.
The present invention with respect to the beneficial effect of prior art is: the Lithium Oxide 98min in its prescription of the opaque glaze that contains Lithium Oxide 98min of the present invention can reduce the firing temperature save energy, prolong furnace life; Reduce melt viscosity, improve temperature flowing property and vitreous degree, improve contamination resistance, strengthen glaze intensity and smooth degree; Reduce thermal expansivity, overcome the glaze crackle, improve thermostability; Improve whiteness, strengthen glossiness; Improve chemicalstability and acid resistance.
