Embodiment 1

[0032] Embodiment 1, the present embodiment carries out according to the following steps:

[0033] (1) Batching: prepare the following components according to weight percentage:

[0034] Potassium feldspar: 37%; Kaolin: 11%; Barium carbonate: 4.6%; Strontium carbonate: 2.7%; Lanthanum carbonate: 1.3%; Lithium carbonate: 1.7%; Zinc oxide: 5.7%; Quartz: 36%.

[0035] (2) Ball milling: add the above-mentioned ingredients to a ball mill, add water according to the ratio of material: ball stone: water = 1:1.8:1, and ball mill to form a glaze slurry;

[0036] (3) Iron removal: the above-mentioned glaze slurry is removed in an 18000 Gauss iron remover;

[0037] (4) Sieve: sieve the glaze slurry after iron removal, the fineness of the sieve is 250 mesh, and the sieve residue is less than 0.02%;

[0038] (5) Stale: stale the sieved glaze slurry for 25 hours and set aside.

Abstract

The invention relates to daily ceramic glaze with a high refractive rate and a preparation technique thereof, which belongs to the field of the preparation of ceramics. The daily ceramic glaze with high refractive rate comprises the following raw materials by weight percent: 36-38% of potash feldspar, 10-12% of kaolin, 4.5-5.5% of barium carbonate, 2.6-2.8% of strontium carbonate, 1.2-1.4% of lanthanum carbonate, 1.6-1.8% of lithium carbonate, 5.5-6.5% of zinc oxide and 34-36% of quartz. The daily ceramic glaze with high refractive rate is prepared by the steps of proportioning, ball milling,iron removing, sieving, aging and the like according to the mixture ratio of the raw materials. By adopting the daily ceramic glaze with high refractive rate and the preparation technique thereof, thefiring range of the glaze is wide, the glaze is free from the influence of a firing atmosphere, a fired porcelain has gorgeous and delicate colour, the glossiness of a glaze layer is as high as 108,and the quality and the grade of a daily ceramic product are greatly enhanced.

Description

technical field [0001] The invention relates to a high-refractive-index daily-use ceramic glaze composition and a manufacturing process thereof, belonging to the field of ceramic manufacturing. Background technique [0002] With the improvement of people's living standards, the quality and grade requirements of daily-use ceramic products are also getting higher and higher, and the brightness of the ceramic glaze layer is a main reason that directly affects the product grade. Because the current glaze raw material formula and production process are relatively old, the surface of fired ceramic products for daily use is not smooth and bright enough. In order to improve the brightness of the surface of daily-use ceramics, meet consumer demand, and occupy the high-end market, the invention improves the raw material ratio and manufacturing process of the glaze to improve the quality and grade of daily-use ceramics. Contents of the invention [0003] The purpose of the present i...
