Description

technical field [0001] The invention relates to a matt protective glaze with a glossiness of less than 3 degrees for thin ceramic tiles, a thin ceramic tile using the matt protective glaze and a preparation method thereof, belonging to the technical field of ceramic tile production. Background technique [0002] Ceramics is a general term for various products made of natural clay, feldspar, quartz and other natural silicate minerals as the main raw materials through crushing, mixing, molding and calcination. Ceramic tiles are the most widely used ceramic products. . With the rapid development in recent decades, the output of ceramic tiles has been ranked first in the world for many years, causing many ceramic raw materials such as clay silicate minerals to face the problems of over-exploitation and resource depletion. , energy, and waste emissions, the development of green and environmentally friendly architectural ceramics has become the goal of the entire industry. The t...
