More Information
Summary:The invention provides a machining method of a selenium-rich ceramic body. According to a preparation method, the surface of a selenium source is wrapped with a pore-forming agent to form a wrapped selenium composite material, and the wrapped selenium composite material is decomposed, combusted or volatilized along with sintering of a ceramic precursor, so that micropores allowing the selenium source to be dispersed on the surfaces of the micropores are reserved in a ceramic phase, accordingly when a selenium-rich ceramic body product is utilized to contain water, the selenium source makes contact with water entering the micropores easily, therefore the possibility that the selenium source gradually releases selenium elements is increased, and a certain selenium supplementation effect is achieved.
