Abstract

The invention relates to a ceramic product which is characterized in that raw material components comprise washing kaolin, Changxing white mud, Fujian pottery stone, feldspar and burned talcum, wherein after blending, sodium humate and sodium silicate are added and ball-milled in a cylinder to obtain a grouting blank of the ceramic product, and the ceramic product is obtained by screening iron, molding, biscuiting, glazing and sintering. According to the invention, a reasonable blank formula, and a preparing and sintering process are adopted, the sintered ceramic product has the advantages of high intensity, high compactness, low water absorption, high dimensional accuracy, corrosion resistance, leakage resistance, good heat stability, no deformation, no crack, and smooth and clear glaze, and has no vices such as pinholes, thin glaze and contracted glaze, so that the defective percentage is reduced, the production efficiency is improved, the production cost is decreased, the artistic degree of the appearance of the ceramic product is promoted; and the method is suitable for high-level ceramic products such as high-grade ceramic wine bottles.

Description

technical field [0001] The invention relates to a ceramic product and its preparation and firing process. Background technique [0002] Traditional ceramic products generally adopt simple batching methods and firing processes. The ceramic products produced are not dense in structure, high in water absorption, and easy to deform, resulting in unclean glaze and easily causing defects such as pinholes, thin glaze, and glaze shrinkage on the glaze surface. To meet the needs of high-level consumer groups. For example, ceramic wine bottles belong to the category of packaging containers, which have high requirements for product strength, water absorption, and specifications. Therefore, the materials of existing ceramic products cannot meet the production of ceramic wine bottles. Ceramic blanks and firing processes for ceramic products. Contents of the invention [0003] In view of the above problems, the applicant has carried out research and improvement, and provides a ceramic...
