Description

technical field

[0001] The invention relates to material technology, in particular to a three-dimensional porous far-infrared negative ion ceramic body, a preparation method and application. Background technique

[0002] Far-infrared negative ion products are widely used in the fields of medical care, energy saving and water treatment. The existing products are mainly powder, ceramic balls, coatings and fabrics. The existing far-infrared negative ion products have simple structure and small effective area, and their far-infrared radiation rate and negative ion release rate still need to be improved.
