Abstract

The invention relates to a selenium-rich ceramic appliance. A ceramic appliance body is fired from raw materials in parts by mass as follows: 30-50 parts of selenium-rich soil, 35-45 parts of petalite, 5-15 parts of spodumene, 1-15 parts of quartz, 10-15 parts of kaolin, 5-8 parts of microcrystalline ceramic powder, 1-3 parts of halloysite nanotubes, 0.5-1 part of nano tungsten carbide powder, 0.5-1 part of nano technetium oxide powder and 0.3-0.5 parts of polyacrylamide. The inner wall of the ceramic appliance body is coated with a selenium-containing coating. The selenium-rich ceramic appliance is prepared from main materials including cheaper petalite and selenium-rich soil, is coated with the selenium-rich coating, has good thermal shock resistance, crack resistance, wear resistance and heat conductivity and can separate out trace selenium element to supplement the human body with selenium.

Description

technical field [0001] The invention belongs to the technical field of inorganic ceramic materials, and in particular relates to a selenium-enriched ceramic utensil which can supplement selenium to food. Background technique [0002] Ceramic cooking utensils have unique advantages such as good heat storage, environmental protection, and corrosion resistance. Various ceramic cooking utensils have appeared in common people's homes and catering industries, competing with traditional metal cooking utensils. [0003] Selenium is currently internationally recognized as an essential trace element for the human body with special physiological functions. If it is deficient, it will easily lead to diseases such as cardiovascular disease, liver disease, cancer, and Kashin-Beck disease. And about 2 / 3 of my country's land is in the selenium deficiency zone, and the normal intake is much lower than the physiological demand value, so it is necessary to supplement the intake of selenium in ...
