Abstract

The invention relates to far infrared self-generated enamel bone china prepared by highly utilizing a desert material, and a preparation process of the far infrared self-generated enamel bone china. The far infrared self-generated enamel bone china is prepared from the following raw materials in percent by weight: 50%-60% of sand from a desert, 10%-20% of pyrophyllite, 8%-15% of knar clay, 10%-18%of coal gangue, 2%-4% of magnesium-based bentonite, 4%-8% of potassium feldspar, 4%-8% of albite, 2%-5% of spodumene, 3%-5% of zirconium silicate and 4%-6% of wollastonite. The preparation process ofthe bone china comprises the following steps: blending according to a formula, performing ball milling, sieving, removing iron, performing filter pressing, performing primary pugging, performing secondary pugging, shaping and firing. The self-generated enamel bone china prepared by the invention is better in toughness, higher in strength and good in thermal stability, is suitable for splat cooling and heating environments, and has better radiation rate and wide spectrum at the same time.

Description

technical field [0001] The invention relates to the technical field of ceramics, in particular to a high-utility desert material far-infrared autogeneous glazed bone china 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 increasingly...
