High-strength ice crack type ceramic product and preparation technology thereof

Abstract

The invention relates to the technical field of preparation of ceramics, in particular to a high-strength ice crack type ceramic product and a preparation technology thereof. The high-strength ice crack type ceramic product comprises a blank and a glaze, wherein the blank comprises 58 parts of kaolin, 24 parts of potassium feldspar, 13 parts of quartz, 17 parts of clay, 2 parts of talcum, 15 partsof melting additive, 20 parts of wollastonite, 14 parts of brucite, 10 parts of sodium feldspar, 8 parts of calcium silicate, 8 parts of barium sulfate, and 6 parts of sepiolite; the glaze comprises45 parts of potassium feldspar, 16 parts of montmorillonite, 26 parts of quartz, 39 parts of sodium feldspar, 3 parts of color oxide, 2 parts of sodium hexametaphosphate, 5 parts of talcum, and 20 parts of calcium carbonate. The preparation technology comprises the following steps of S1, preparing of the materials; S2, drawing of the blank; S3, plain firing; S4, glaze applying; S5, firing. The high-strength ice crack type ceramic product prepared by the preparation technology has the advantages that the mechanical strength is high, the color is transparent and clear, and the cracks are fine and regular.

Description

technical field [0001] The invention relates to the technical field of ceramic preparation, in particular to a high-strength ice-crack ceramic product and a preparation process thereof. Background technique [0002] China's porcelain culture has a long history. Celadon is famous for its fine quality, dignified and simple shape, and pure and white color. It has the reputation of "the flower of porcelain". Celadon originated from the original porcelain in the Shang Dynasty, and reached its peak in the Song Dynasty. In the course of 3,000 years of development, celadon has grown from birth to maturity. The texture of ice is a symbol of the noble character of the Chinese nation. In the course of the development of Chinese civilization, it is a vivid symbol of national culture. [0003] Ice-crack celadon is actually a kind of glazed porcelain with oblique cracks. The appearance of cracks is a defect in the firing process, that is, the cracking of the glaze surface caused by the m...

At the same time, when the content of iron in the glaze is different, the glaze color will also show different hues such as moon white, pink green, and plum green. Unfortunately, due to the production process of ice cracks, most of the glazes of porcelain before the Song Dynasty were patterned. Pieces, kiln workers try to avoid but difficult to control
