Abstract
In some examples, a method including positioning a first ceramic or ceramic matrix composite (CMC) part and a second ceramic or CMC part adjacent to each other to define a joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part; and depositing an aqueous braze paste at least one of in the joint or adjacent the joint, wherein the aqueous braze paste comprises water, a water-soluble polymeric binder, and a silicon-based powder alloy.

A method comprising:
- positioning a first ceramic or ceramic matrix composite (CMC) part and a second ceramic or CMC part adjacent to each other to define a joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part;
- and
- depositing an aqueous braze paste at least one of in the joint or adjacent the joint, wherein the aqueous braze paste comprises water, a water-soluble polymeric binder, and a silicon-based alloy powder.
An aqueous braze paste comprising water, a water-soluble polymeric binder, and a silicon-based alloy powder, wherein the braze paste is configured to connect a first ceramic or ceramic matrix composite (CMC) part and a second ceramic or CMC part adjacent to each other via a braze joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part.
An assembly comprising:
- a first ceramic or ceramic matrix composite (CMC) part;
- a second ceramic or CMC part adjacent to the first ceramic or ceramic matrix composite part, wherein the parts define a joint between adjacent portions of the first ceramic or CMC part and the second ceramic or CMC part;
- and
- an aqueous braze paste at least one of in the joint or adjacent the joint, wherein the aqueous braze paste comprises water, a water-soluble polymeric binder, and a silicon-based alloy powder.
