Problems solved by technology

However, when Dehua white porcelain is used for daily ceramic tea tableware, there are defects such as poor thermal shock resistance, narrow melting temperature range and many pinholes.
After a thermal stability test of rapid cooling and rapid heating and cracking at a temperature of 140°C to 20°C, while the national standard requires a thermal stability test, a rapid cooling and rapid heating at a temperature of 180°C to 20°C does not crack, and the thermal stability of some export products Stability test, the standard requirement is that the temperature is 200 ℃ ~ 20 ℃ once rapid cooling and rapid heating without cracking, especially for large-scale products, so this defect limits the scope of use of Dehua white porcelain as tea tableware
Some technicians have been overcoming this technical problem. After technical breakthroughs, some products have been tested for thermal stability at 180°C to 20°C for one-time rapid cooling and rapid heating without cracking, but it cannot be guaranteed stably, and the pass rate is low. standard

Abstract

The invention discloses a high-performance transparent glaze for white porcelain and a preparation method thereof, belonging to the technical field of daily-use ceramic glazes. The high-performance transparent glaze of white porcelain of the present invention is composed of the following components: terrazzo feldspar, kaolin, burnt talc, dolomite, barium carbonate, calcined zinc oxide, terrazzo, glaze stabilizer, expansion coefficient regulator. The preparation method of the high-performance transparent glaze of white porcelain comprises the following steps: preparing materials, aging, and glaze firing. The high-performance transparent glaze of white porcelain prepared from the raw materials described in the present invention has a high melting temperature and a wide range of melting temperature, reaching 1290-1330°C. The glaze surface is less affected by kiln temperature fluctuations, and the glaze surface There are few pinholes, the glaze surface is bright and smooth, and the expansion coefficient of the glaze surface is adjustable, which adds a stress to the surface of the ceramic body, and achieves the effect of rapid cooling and rapid heating at 200 ° C ~ 20 ° C without cracking.

Description

technical field [0001] The invention belongs to the technical field of daily-use ceramic glazes, and in particular relates to a high-performance transparent glaze for white porcelain and a preparation method thereof. Background technique [0002] Dehua Kiln has a long history and has gone through thousands of years of wind and frost, leaving a glorious stroke in the history of Chinese ceramics. In the history of world ceramics, the word "China White" has become synonymous with Dehua White Porcelain. (BLANC DE CHINE) is the French praise for Dehua white porcelain in the Ming Dynasty. Dehua white porcelain has "ivory white" and "pig white" because of its fine production, firm texture, crystal clear jade, and glaze as moist as fat. "Oil white", "velvet white" and other good names have a unique style in my country's white porcelain system, occupy an important position in the history of ceramic development, and have the reputation of "Oriental Art" internationally. However, when D...
