Co-sintered ceramic for electronic devices
First Claim
Patent Images
1. A method for manufacturing a ceramic housing for a portable electronic device, comprising:
- forming a first part from a first ceramic material that is optically opaque to define a partially enclosed volume and an opening into the partially enclosed volume;
forming a second part from a second ceramic material that is optically transparent;
positioning the second part over the opening of the first part; and
sintering the first part and the second part, thereby fusing the first part to the second part to form the ceramic housing.

Abstract
A ceramic structure and methods for making the ceramic structure are disclosed. Multiple parts may be molded; the parts may be molded from the same or different ceramic materials. The parts may be formed in the same mold and may be adjacent to and/or attached to one another as a result of molding. The parts may be placed in a sintering furnace and sintered simultaneously. Simultaneously sintering the parts forms a unitary structure from the parts.

9. A housing for a portable electronic device, comprising:
-
a first part formed from a first ceramic material that is opaque and defines an opening; and a second part formed from a second ceramic material that is transparent and is positioned at least partially within the opening of the first part;
whereinthe first and second parts are fused together during sintering. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method for forming a co-sintered structure, comprising:
-
molding, using first mold piece and a second mold piece, a first part from a first ceramic slurry; co-molding to the first part, using the first mold piece and a third mold piece, a second part from a second ceramic slurry; and co-sintering the first and second parts, thereby forming the co-sintered structure, the first part being optically opaque and the second part being optically transparent and positioned at least partially within an opening defined within the first part. - View Dependent Claims (17, 18, 19, 20, 21)
