Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-utility desert material far-infrared self-generated glazed porcelain and a preparation process thereof. Background technique [0002] With the continuous development of ceramic technology, people use different raw materials and different processes to make ceramics, and many new types of ceramics have emerged. Bone China and far-infrared ceramics are two of the more popular types. Bone China is a recognized high-grade porcelain, and Dehua Jade Porcelain is a notable representative of bone china. It is mainly made of animal bone ashes as the main raw material, and a certain amount of kaolin, quartz, feldspar, etc. are added to make soft porcelain. It has the advantages of fine porcelain, high whiteness, high transparency, smooth glaze, and high mechanical strength. However, due to the extensive development and utilization of mineral resources, the ore is becoming increasing...
