Abstract
The application provides a SiOC ceramic and a preparation method thereof, relates to the technical field of thermal insulation materials, and comprises the following steps: ceramic precursor blanks and ceramic fiber membrane precursors are respectively prepared; the ceramic precursor blank is in a honeycomb structure; the ceramic fiber membrane precursor is assembled with the ceramic precursor blank, so that the ceramic fiber membrane precursor covers through holes of the honeycomb structure, a combined part is obtained, and then the combined part is subjected to ultraviolet curing; and the combined part after the ultraviolet curing is subjected to pyrolysis treatment, so that the SiOC ceramic is obtained. Through the ultraviolet curing and the pyrolysis treatment of the combined part after the assembly of the ceramic precursor blank and the ceramic fiber membrane precursor, the obtained SiOC ceramic not only has the lightweight and high-strength performance of the porous ceramic material, but also has the excellent thermal insulation performance of the ceramic fiber membrane.
