Abstract

The invention provides a far infrared ceramics pellet heated by the microwave under the normal temperature and the manufacture method. The mass fraction Al2O3:30-38percent, MgO:12-20 percent, SiO2:45 -55 percent and the mass fraction MnO2:55-65 percent, Fe2O3:35-45 percent are mixed separately and evenly; after the former being calcined under certain high temperature, TiO 2, ZrO2, SiC are added and mixed at the mass fraction 57-63 percent, 17-23 percent, TiO2:1 percent, ZrO2:2 percent, SiC:15-19 percent. The diameter of the powder body is D95 less than or equal to 1.0 Mum after pellet grinding. The powder body is fabricated to ceramics semi product the diameter of which is 0.3-5.0mm after being dried for hours to be adglutinated the ceramics pellet kept under certain high temperature. Theceramics pellet is carried on centrifugal polished leading to the surface roughness is Ra less than or equal to 20 Mum. The ceramic pellet is able to put in the home use microwave oven to heat up directly for 1-5 minutes up to 30-90 DEG C.

Description

Technical field [0001] The invention relates to a far-infrared ceramic ball, in particular to a far-infrared ceramic ball that can be heated by microwave at normal temperature. Background technique [0002] Human tissues are composed of 60-70% water molecules, and the rest are organic macromolecules such as proteins. Because water molecules and organisms are selective in the reflection, transmission and absorption of infrared rays, the far-infrared wavelength radiated by the human body is 5-25μm. The peak wavelength is 9.25μm, of which the 8-15μm wavelength accounts for 60% of the total radiant energy emitted by the human body. The human body can emit the far infrared rays of the above wavelengths and can also absorb the far infrared rays of this band well. After the infrared rays of this band are absorbed by the human body , Can make the water molecules in the body resonate to activate the water molecules, enhance the binding force between the molecules, and then activate the bi...
