Abstract

The invention relates to a preparation method of a split-phase blue lily glaze. The preparation method comprises the following steps of: preparing a boron fused block, namely, uniformly grinding feldspar, quartz, calcite, boric acid, NaNO3 and Li2CO3 in a mortar, putting the mixture into a high-temperature furnace crucible at a high-temperature stage for calcining to 1,260 DEG C, melting for 10 minutes and hardening; mixing the feldspar, the quartz, Suzhou clay, the calcite, talc, ZnO, calcium phosphate, the boron fused block, Fe2O3, cellulose, sodium tripolyphosphate and sodium carboxy methyl cellulose (CMC), performing fine grinding on the mixture until the mixture is 250 meshes and adjusting the specific weight of glaze slurry to be 1.7 g/cm<3>; uniformly applying the glaze slurry to a blank, raising the temperature to 1,160 to 1,240 DEG C, preserving heat for 20 to 50 minutes and cooling naturally; coloring according to a split-phase mechanism produced by a melt in a glaze baking process; and making a small number of coloring oxides produce large coloring capability and allowing a glaze surface to produce a special pattern which is similar to a lily under the action of a split phase. Therefore, the blue lily glaze which has low cost and high stability and only contains a small amount of Fe is obtained by the preparation method.

Description

The preparation method of the blue lily fancy glaze of a kind of phase-splitting

Technical field

The present invention relates to the blue fancy glaze of a kind of phase-splitting the preparation method, be specifically related to a kind of preparation method who can be used for building Western-style watt, colored glaze watt, the art pottery and the blue fancy glaze of other medium temperature ceramics.

Background technology

Tradition blue glaze (non-blue and white coloured silk) is a tinting material with natural earthy cobalt, except that containing cobalt oxide, also contains ferric oxide and manganese oxide.Blue glaze sees in the low temperature coloured glaze coloured silk the earliest, and the appearance of high temperature blue glaze is in the Yuan Dynasty.Go into bright after, particularly when Xuande, the many and matter U.S. of blue glaze implements is pushed top grade into Xuande porcelain.During to clear Kangxu, blue glaze, multiple new variety such as sky blue more appear spilling.

Now preparing blue glaze employing the most general maximum methods is to add colorant in the parent glaze, and this method need prepare colorant in advance, and the technological process of preparation colorant is quite complicated and technical stronger.What toner mainly adopted is zirconium vanadium blue, cobalt blue etc.Cobalt blue costs an arm and a leg, and seldom is used for the preparation of blue glaze except that being used as blue and white coloured silk.The preparation principle of zirconium vanadium blue colorant is mainly vanadium with V ⁴⁺Form displacement ZrSiO ₄In Zr ⁴⁺, form substitutional solid solution, cause ZrSiO ₄Lattice distorts, and makes colorant form a wide reflection peak around at visible reflectance spectrum 475nm place, present blueness (Yu Kangtai, Zhu Zhibin. the valence state of vanadium research in the zirconium vanadium blue colorant. ceramic journal, 2000 (12): 186-189.).The technological process of synthetic colorant need pass through technologies such as calcining, elutriation, energy consumption height, pollution greatly, relative cost is higher, does not meet the needs of current international community energy-saving and emission-reduction, demands technological improvement and raising urgently.

Though present stage, the technology of blue glaze was ripe relatively, the technology of preparing of blue fancy glaze especially only contains the painted blue fancy glaze of ferric oxide without the zirconium vanadium blue colorant and does not appear in the newspapers.

Summary of the invention

The objective of the invention is to overcome the deficiencies in the prior art, a kind of low cost, high stability are provided, have only contained the preparation method of the blue lily fancy glaze of phase-splitting of small amount of Fe.

For achieving the above object, the technical solution used in the present invention is:

1) preparation of boron frit: by mass percentage with 45.5% feldspar, 15.2% quartz, 7.6% calcite, 22.7% boric acid, 4.5% NaNO ₃With 4.5% Li ₂CO ₃In mortar, grind even compound, compound is put in High Temperature Furnaces Heating Apparatus be fired to 1260 ℃ crucible, melt that hardening gets the boron frit after 10 minutes;

2) preparation of glaze slip: by mass percentage with the feldspar of 40-55%, the quartz of 10-30%, the Suzhou soil of 1-5%, the calcite of 1-5%, the talcum of 2-10%, the ZnO of 1-5%, the calcium phosphate of 1-8%, the boron frit of 1-15%, 5% Fe ₂O ₃, 1% Mierocrystalline cellulose, 0.5% tripoly phosphate sodium STPP and 0.5% CMC mix, and are finely ground to 250 orders, and modulation glaze slip proportion is 1.6-1.7g/cm ³

3) glaze slip is executed equably applied on base, be warming up to 1160-1240 ℃, be incubated 20-50 minute, naturally cooling promptly obtains the blue lily fancy glaze of phase-splitting then.

The present invention utilizes the parvafacies mechanism that melt produces in the glaze sintering process to carry out painted by the prescription modulation.Phase-splitting can make the glaze melt produce the non-miscible separation of liquid liquid, ferric oxide is present in microfacies rather than the whole glassy phase, therefore can improve the concentration of iron ion in the microfacies, make a small amount of coloring oxide produce bigger tinting strength, and glaze has produced many stripeds and spot and painted ionic package action stability has been improved because of microfacies under the effect of phase-splitting.
