In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings. Wherein like parts are given like reference numerals.
Fig. 1 is a schematic perspective view showing a black ceramic component for an electronic device according to an embodiment of the present invention, wherein the ceramic component 100 may be a panel, a back cover, a cover plate of an electronic device, or the like for an electronic device such as a mobile phone. The ceramic part 100 may be manufactured using an existing injection molding and sintering process (those skilled in the art may understand the above conventional process flow with reference to the two prior art documents cited in the background section), and the ceramic part 100 thus manufactured may be easily discolored during use due to unevenness of surface porosity, and thus the entire ceramic part may be blackened through a blackening process of carburizing and sintering to avoid an adverse effect of discoloration of the appearance.
It is normally known that ceramics such as ordinary zirconia have a dielectric coefficient much higher than that of metals, are not conductive per se, and are not problematic per se for covering or protecting electronic devices. However, after the carburizing and sintering treatment mentioned in the background section, since the carbon particles infiltrated into the pores of the ceramic are good conductors, the blackened ceramic part becomes a conductor, which causes adverse effects when it is applied to electronic devices, and the insulation treatment is required instead, which greatly limits the application of the black ceramic in the field of electronic devices.

The black nonconductive part 300 formed on the ceramic body 200 may be manufactured by a manufacturing method including dewaxing and degreasing an injection-molded ceramic body, heating and sintering the ceramic body in a vacuum furnace together with manganese oxide powder, and gasifying the manganese oxide powder to penetrate into the ceramic body to finally obtain the black ceramic part 100 having the black nonconductive part 300.
That is different from prior art, the utility model discloses a manganese oxide powder and ceramic body vacuum sintering together for the material that gasifies in the infiltration ceramic body is black manganese oxide, but black graphite, therefore the whole black ceramic part 100 that obtains is black, and this kind of black ceramic part 100 itself is nonconducting, therefore be applied to electronic equipment and can not produce adverse effect to electron device, can exert its intensity and hardness that are superior to the metal, good feeling, the advantage of lighter quality, the defect that current black ceramic part is electrically conductive after the carburization sintering has been avoided.
Further, in another embodiment of the present invention, the ceramic body 200 may further have a black conductive portion 400. That is to say, according to the prior art, a black conductive ceramic component can be obtained by those skilled in the art, according to the foregoing embodiment of the present invention, a black non-conductive ceramic component can also be obtained, so that the advantages and disadvantages of the two can be combined to obtain a black ceramic component 100 which is black on the whole and has both a non-conductive portion 300 and a conductive portion 400, the purpose of the black ceramic component 100 with such a structure is to make the conductive portion 400 into a conductive circuit, and separate the conductive portion 400 by using the non-conductive portion 300, so as to form a structural form similar to a circuit board, provide a medium capable of connecting an internal circuit of an electronic device for components such as a ceramic housing, and provide a flexible structural basis for the design of the electronic device.
