Abstract
A ceramic slurry for forming a ceramic article includes a binder, a first plurality of ceramic particles having a first morphology, a second plurality of ceramic particles having a second morphology that is different from the first morphology; and a photoinitiator. A method for using this slurry for fabricating ceramic articles is presented as well.
Claims22
A ceramic slurry for forming a ceramic article, comprising:
- a binder;
- a first plurality of ceramic particles having a first morphology;
- a second plurality of ceramic particles having a second morphology that is different from the first morphology;
- and
- a photoinitiator;
- wherein the binder comprises an organic resin component and the binder further comprises a siloxane.

A method for fabricating an article, the method comprising:
- depositing a slurry composition onto a working surface;
- curing at least a portion of the slurry composition to form a green ceramic material;
- debinding the green ceramic material to form a brown ceramic material;
- and
- sintering the brown ceramic material to form a final ceramic article;
- wherein the slurry comprises:
- a binder;
- a first plurality of ceramic particles having a first morphology;
- a second plurality of ceramic particles having a second morphology that is different from the first morphology;
- and
- a photoinitiator.
