Abstract
A ceramic article. In some embodiments, the ceramic article includes a ceramic body composed of a ceramic material; and a first conductive trace, the first conductive trace having a first portion entirely within the ceramic material, the first portion having a length of 0.5 mm and transverse dimensions less than 500 microns, the ceramic material including a plurality of ceramic particles in a ceramic matrix.
Claims10
A method for manufacturing an article, the method comprising:
- forming a layer of a preceramic polymer resin on a surface of a partially-fabricated article;
- selectively curing the layer in a first region of the surface after the forming of the layer of the preceramic polymer resin on the surface;
- forming one or more patches of a slurry of metallic particles, in a second region of the surface, the second region being different from the first region;
- and
- wherein after the forming of the layer of the preceramic polymer resin on the surface and after the forming of one or more patches of the slurry of metallic particles, the method further comprises performing pyrolysis on the partially-fabricated article in an inert atmosphere at one or more temperatures between 600° C. and 1000° C. for 10 minutes to 100 minutes after heating at a heating rate of between 0.5° C./min and 5° C./min.
