Abstract
The present invention relates to a positioning and shaping process technique of artistic glaze on domestic ceramic. In the technique, crystal seeds, such as zirconium oxide, willemite, zinc oxide, etc., are put in preset positions to position and shape crystal patterns. The qualified rate of products is largely enhanced, and the artistic effect of the appearance of the products is improved.
Description
The invention belongs to the domestic ceramics technical field of producing.
Willemite crystalline glaze is a typical species of ingotism crystalline glaze.Because the glaze high temperature viscosity is little, glaze often trickles in a large number to the goods bottom, and brilliant flower also maximum dose be distributed in the goods bottom, had a strong impact on the raising of qualification rate.For improving brilliant flower distribution, Nuo Dun (Norton) has proposed the location crystallization method of high temperature dibbling in nineteen thirty-seven on " J, Am, Ceram, Soc ", but the actually operating operation is loaded down with trivial details, does not have industrial implementation to be worth, at the end of the seventies, this institute has successfully solved location crystalline problem.Crystalline substance is spent and can have been enlarged crystalline range in predetermined position growth, has increased substantially qualification rate, spends in the form of annular discsly but locate crystalline substance, and flower shape dullness has influenced appearance effect.
Purpose of the present invention is to adopt different types of crystal seed with the location crystallization method, burns out brilliant flower stationkeeping and the different crystalline glaze ceramic product of form.
Main points of the present invention are to adopt glass powder, feldspar, zinc oxide to prepare the crystallization glaze, and its Chemical Composition is:
SiO
255.17%, TiO
20.03%, AlO
33.79%, Fe
2O
20.29%, CaO3.98%, MgO2.56%, K
2O1.75%, Na
2O7.44%, ZnO24.92%, its glaze formula of NiO1.00% are:
0.031K
2O
0.202Na
2O
0.120CaO 0.063Al
2O
31.553SiO
2
0.107MgO 0.003Fe
2O

0.517ZnO
0.023NiO
Its glaze needs fully levigate through ball mill, and its granulometric composition of back that sieves is:
63-10μ 40.36% 10-5μ 22.42%
5-2μ 17.94% ＜2μ 19.28%
With zirconium white, willemite and zinc oxide is crystal seed.The zirconium white crystal seed adopts commercially available technical grade zirconium white screening to get final product, the willemite crystal seed adopts by zinc oxide and silicon-dioxide, through high-temperature roasting and synthetic willemite, zinc oxide crystal seed adopts the technical pure zinc oxide of 1300 ℃ of roastings to get final product, granularity all is controlled at 0.16～0.42mn.
The mode of dibbling has three kinds: one is dibbling under the glaze, is about to crystal seed and directly is bonded on the base substrate; It is about to crystal seed and is bonded on the glaze two for executing kind on the glaze; It three is a glaze embedding kind, is about to crystal seed and is pressed in the glaze layer.Above-mentioned three kinds of modes are the best with glaze embedding kind.
Calcining system: room temperature～1000 ℃ 1000～1260 ℃
10℃/min 5℃/min
Holding temperature is controlled between 1140 ℃～1120 ℃, as low again, then all forms discoid brilliant flower.
According to the present invention, can on same goods, obtain the crystalline substance flower of two kinds of forms, willemite or zinc oxide crystal seed grow into discoid brilliant flower, and the zirconium white crystal seed generates the flower-shaped brilliant flower of stone column.
The present invention compared with the prior art, have simple to operate, qualification rate is high, product appearance is imbued with the advantage of aesthetic feeling.
Claims (2)
1, setting technology in the location of the willemite crystalline glaze in a kind of domestic ceramics production technique when selecting crystal seed for use, is not only used willemite and zinc oxide to be crystal seed, and be it is characterized in that: uses the technical pure zirconia particles to be crystal seed.
2, by the location setting technology of the willemite crystalline glaze in the described domestic ceramics production technique of claim 1, its holding temperature is controlled between 1140 ℃～1120 ℃.
