Star drill crackle glaze, glaze slip and ceramic thereof

Abstract

The invention belongs to the field of ceramics, and discloses a star-diamond cracked glaze, glaze slip and ceramic thereof, and the star-diamond cracked glaze comprises the following chemical components by mass: 65 to 80% of SiO2, 10 to 15% of Al2O3, 2 to 7% of K2O, 3 to 10% of Na2O, 0 to 0.5% of Fe2O3, 0 to 0.5% of CaO, 0 to 1% of MgO, and 0 to 0.5% of TiO2. The expansion coefficient of the star drill crack glaze in some examples is larger than that of a biscuit and a cover glaze, in the cooling process of the fired blank glaze, the shrinkage of a star drill crack glaze layer is larger than that of a blank body, the blank body is subjected to pressure stress, the glaze is subjected to tensile stress, and the glaze layer cracks to form net-shaped cracks. Meanwhile, local yielding and plastic deformation occur in a local weak area of the glaze polishing layer, surrounding materials do not yield, transverse shrinkage needed during local stretching is limited, microcracks are generated between the star drill cracked glaze and the glaze polishing layer, light rays are completely reflected on the surfaces of the microcracks, the star drill effect is formed, and the unexpected effect is achieved.

AI Technical Summary

Benefits of technology

This patented technology allows for improved resistance against damage caused by thermal shocks during firing processes such as firebricks or other products used under extreme conditions. It achieves this through adding specific elements like zirconium dioxide into certain types of glass compositions called sintered ones with higher coefficients of expandability compared to regular bodies while maintaining their original shape when cooled down below room temperatures. These added components help prevent fractures from occurring due to changes made overtime. Additionally, these techniques can be applied even if there were any defects within them themselves.

Problems solved by technology

In this patented technical problem addressed in the patents text relates to finding ways to prevent damage caused from cracks formed when producing ceramically insulated materials such as buildings or tiles due to excessive heating generated through flames used inside fireproof furnaces.
