Description

technical field [0001] The invention relates to the technical field of hot water pots, and more specifically, to a method for preparing far-infrared ceramic materials. Background technique [0002] Infrared radiation ceramic material is a new type of light-to-heat conversion material, which has been widely used in many fields such as environmental protection, home appliances, and medical treatment. Infrared ceramic material is a kind of ceramic powder material with high radiation rate and radiation intensity in the far infrared band, which is prepared by using ceramic powder processing technology with oxides, carbides, nitrides, etc. as raw materials. Currently commonly used far-infrared radiation ceramics mainly include silicon carbide series, iron-manganese-nickel-cobalt-copper series, negative ion powder and other black or dark far-infrared radiation ceramics and zirconia series, aluminum-magnesium-silicon-zinc-titanium- Rare earth and other white far-infrared radiation...

AI Technical Summary

Problems solved by technology

The sol-gel process uses alkoxide as a raw material, which is expensive and has few varieties; the distribution of nano-ceramic powder particles obtained by the co-precipitation process is uneven. If anhydrous ethanol is used to dehydrate and prevent hard agglomeration, it is unsafe and expensive.

[0003] In the prior art, the emissivity of far-infrared ceramic materials is low after high-temperature processing, and they are not resistant to high temperatures. This makes it necessary to develop a far-infrared ceramic material that can withstand high temperatures, which can not only meet high temperature invariance, but also maintain the original efficacy.
