Manufacturing Method of High Efficiency Far Infrared Radiation Blackbody Ceramics Using Onggi Clay

摘要

In the conventional Onggi clay, 60% before and after 60% of the far-infrared radiation amount is solved. In the present invention, the purpose of the present invention is to solve the clay having an excellent radiation amount of 90% or more. It can be a material for various development such as building materials, and is particularly useful as a food processing and storage container.
