MULTIPURPOSE CERAMIC COMPOSITION AND USAGE THEREOF [Technical Field]

The present invention relates to multipurpose ceramic composition and the use thereof, more specifically to the composition comprising silicone, germanium and magnesium in the regular ratio and the use thereof as far infrared dispenser, the filter for water purifier and the lagging material for oven, heater and heating apparatus.

[Background Art] Generally, ceramic is named as fine ceramics or new ceramics, which is also known as ceramics produced by the extruding method and the firing method which can be highly controlled the chemical composition minutely composed with an artificial material or a carefully selected material, unlike the conventional ceramics such as ceramic ware. Fine ceramics can be used in many purposes because it is more efficient than the conventional ceramics and has a new ability hitherto unknown to the art.

Fine ceramics can be divided into oxide based ceramics and non-oxide based ceramics, in which oxide based ceramics comprise alumina(Al ₂ O ₃ ), ferrite(Fe ₂ O ₃ ), zirconia(ZrO ₂ ) and titania(TiO ₂ ) etc., and non-oxide based ceramics comprise silicon carbide(SiC), silicon nitride(Si ₃ N ₄ ) etc. Recently, unearth abilities of the fine ceramics such as thermal ability, mechanical ability, biological and chemical ability, electric and electronic ability and optical ability have been found.

In the mean time, far infrared is a radiation having 4 to 400 μm of wavelength. According to the fact recently found out, it has been identified by the experiments that far infrared has a characteristic of interfering in all organic material to change its molecular motion besides general characteristics as a radiation. Especially, far infrared having 8 to 20 μm of wavelength have good permeability and act on organic materials to activate it. Particularly, it is known that as far infrared being applied to the human structures, it cause resonances in constituent molecular of the human structures to activate molecular motion and thus to stimulate the circulation of blood and metabolism. The efficiency of far infrared like this have been discovered gradually and hereupon various products utilizing far infrared have been forwarded.

Accordingly, there are many studies about the material which releases far infrared having characteristics described above. According to the thing to be found out to the present time, various ceramics are used as far infrared radiating structures, in which ceramic sources and natural mineral sources are used as materials for synthesizing ceramic. Especially, ceramic sources include materials on the basis of alumina, silicone, zirconia, titania etc. Natural mineral sources include clay, mica, petalite, cordierite, mullite or sphene etc. and it used in synthesizing of far infrared radiating ceramic materials. Such far infrared radiating ceramics are classified in accordance with its constituents, such as 1. alumina silicone series, 2. zircon series, 3. cordierite series and 4. synthetic product of other ceramic radiating materials. Far infrared radiating structures of alumina silicone series are made of kaolinite, clay and talcum obtained in nature as main ingredient and it formed into the crystal by firing rather than non-firing in

order to increase far infrared radiating efficiency. Also, far infrared radiating structures are constructed by mixing proper materials with proper amount according to the use. Also, far infrared radiating structures of zircon series are made of zircon sand obtained in nature as main ingredient, and it constructed by adding small amount of transition element such as Fe ₂ O ₃ and MnO ₂ , and used as a raw material of tube type far infrared radiating structures and coating type far infrared radiating structures. Also, the far infrared radiating structures of cordierite series are made of kaolinite, clay and talcum obtained in nature as main ingredient and it used as a raw material of honeycomb type far infrared heating element which is prepared by press molding because it has high resistance to the heat-shock and very low thermal expansion coefficient due to the addition of MgO. Also, far infrared radiating structures synthesized by other ceramic radiating materials include one of adding Si ₃ N ₄ , SiC etc. to increase mechanical strength of ceramics. Also, there is far infrared radiating ceramic material, in which CuO, Fe ₂ O ₃ , MnO ₂ , NiO, CoO etc. are added to increase far infrared radiating efficient.

Other natural materials radiating the far infrared include silicone, ferric oxide, titanium oxide, alumina calcium oxide, magnesium oxide, sodium oxide, potassium oxide. In order to constitute ceramics having high far infrared radiating efficiency, natural mineral material or ceramic materials are mixed according to its use, and then the mixture are sintered and processed. In accordance with the use of the ceramics, namely far infrared radiating ceramic materials for low temperature or high temperature and the required uses, mixing materials and mixing ratios can be

varied. Thus, in constituting far infrared radiating ceramics, mixing of materials, management of plastic temperature, minute mixing ratio and mixing technique of other characteristic materials has been become the know-how

However, it is the actual circumstances that the above various ceramic materials were studied and referred nothing but to far infrared radiating ability, studied to water purification ability or emission ability of radiation energy in accordance with the constitution of the ceramic composition did not performed.

Accordingly, the present inventor accomplish the present invention by establishing the fact that the ceramic composition having specific constitution is superior in far infrared radiating ability, excellent in water purification as well as have good emission ability of radiation energy to provide the use for the lagging material for oven, heater and heating apparatus.
