Abstract

The invention relates to a preparation method of an opaque glaze. Firstly, the molar number of all alkaline oxides in the formula of the opaque glaze is determined, and then the molar ratio of silicon oxide in the formula is controlled to be 3.00-4.50 and the molar ratio of aluminium oxide in the formula is controlled to be 0.30-0.40, thus the glaze is opacified in an opacifying area to form the opaque glaze. The raw materials adopted by the preparation method are low in cost, the preparation process is simple and is easy to control, and the opaque glaze is high in brightness, thus the preparation method has a wide application prospect.

Description

A kind of preparation method of opaque glaze
Technical field
The invention belongs to ceramic (pottery) field, specifically a kind of preparation method of opaque glaze.
Background technology
Opaque glaze is also called devitrification glaze.When the glaze layer of visible rays by pottery, be subject to the scattering of disperse phase in glaze and produce light tight phenomenon and be devitrification.The formation mechenism of opaque glaze can be divided into three kinds: one be formed in the sintering process of glaze a large amount of, granular size visible wavelength range, the tiny crystals that is evenly distributed; Two is glassy phases (i.e. glass phase-separating) that formation two kinds is immiscible in the sintering process of glaze; Three be formed in the sintering process of glaze a large amount of, granular size visible wavelength range, the micro-bubble that is evenly distributed.Wherein first, second kind of method is many adopts in production practice, and the third method is difficult to realize in production.With regard to first method, in glaze, add nominal mass zirconium white, zirconium silicate, titanium oxide, cerium oxide, stannic oxide etc. is all adopted in production practice, make it to form crystal small in a large number in the sintering process of glaze thus make glaze layer devitrification, it is the most widely that the method uses, but cost is higher, raw material not environmentally.
Summary of the invention
The technical problem to be solved in the present invention is to provide the preparation method of opaque glaze of a kind of with low cost, environmental protection, superior performance.
For solving above technical problem, technical scheme of the present invention is: a kind of preparation method of opaque glaze, is characterized in that: carry out feed proportioning by following glaze formula:
Wherein Y=0.30 ~ 0.40 mol, X=3.00 ~ 4.50 mol;
Through ball milling, glazing, burn till acquisition goods, wherein firing temperature is 1220 ~ 1250 DEG C, firing time is 2 ~ 3h, soaking time is 0.5h.
Described raw material is feldspar, quartz, burning talcum, clay, chainotte, light calcium carbonate.
Described feed particles fineness is less than 100 orders.
Described goods glaze paint whiteness is 70 ~ 77/%.
First the present invention determines the mole number of each basic oxide in glaze formula, then by changing the mol ratio of silicon oxide, aluminum oxide in glaze formula, thus make the shape of glaze be in milkiness district to form opaque glaze, the method low cost of raw materials, technique is simple and easy to control, can realize suitability for industrialized production, therefore have wide market outlook.
