Abstract
Provided herein are methods of manufacturing a ceramic article. The methods may include providing a liquid-state pre-ceramic polymer component, disposing the liquid-state pre-ceramic polymer component on a support, curing the liquid-state pre-ceramic polymer component, and subjecting the pre-ceramic polymer to pyrolysis. Apparatuses and systems for manufacturing a ceramic article also are provided.
Claims18
A method of manufacturing a ceramic article, the method comprising:
- providing a liquid-state pre-ceramic polymer component, wherein the liquid-state pre-ceramic polymer component is an aqueous paste;
- disposing the liquid-state pre-ceramic polymer component on a support, wherein the support is maintained at a temperature that is (i) equal to or (ii) less than the freezing point of the liquid-state pre-ceramic polymer component;
- curing the liquid-state pre-ceramic polymer component to form a solid-state pre-ceramic polymer component;
- and
- subjecting the solid-state pre-ceramic polymer component to pyrolysis at a temperature and time effective to form the ceramic article.
A method of additive manufacturing a ceramic article, the method comprising:
- providing a liquid-state pre-ceramic polymer component, wherein the liquid-state pre-ceramic polymer component is an aqueous paste;
- disposing a first portion of the liquid-state pre-ceramic polymer component on a support that is at a temperature (i) equal to, (ii) less than, or (iii) about 0.1% to about 5% greater than the freezing point of the liquid-state pre-ceramic polymer component;
- exposing the first portion of the liquid-state pre-ceramic polymer component to ultraviolet light effective to substantially cure the first portion of the liquid-state pre-ceramic polymer component to form a first solid-state pre-ceramic polymer component;
- disposing a second portion of the liquid-state pre-ceramic polymer component at least partially on the first solid-state pre-ceramic polymer component;
- exposing the second portion of the liquid-state pre-ceramic polymer component to ultraviolet light effective to substantially cure the second portion of the liquid-state pre-ceramic polymer component to form a second solid-state pre-ceramic polymer component;
- and
- subjecting the first and second solid-state pre-ceramic polymer components to pyrolysis at a temperature and time effective to form the ceramic article.
