A method for rapidly preparing ultra-thin ceramic sheets

Abstract

The invention relates to a method for quickly preparing an ultrathin ceramic chip. The method comprises the following steps: utilizing a laser chemical vapor deposition technique to take a corresponding metallic organic source as a precursor raw material and deposit a uniform ceramic layer on a specific substrate under an activating effect of laser, and then separating the substrate from the prepared ceramic layer in the manner of ablating or grinding, thereby acquiring a single high-compactness specific ultrathin ceramic chip. The method not only can greatly reduce the sintering temperature of the ceramic chip and is beneficial to reducing energy consumption, but also is simple in posttreatment process, short in production period, lower in cost and huge in application prospect in the aspect of industrial production.

Description

technical field

[0001] The invention relates to the technical field of ceramic materials, in particular to a method for rapidly preparing ultra-thin ceramic sheets. Background technique

[0002] Special ceramics refer to ceramics with special mechanical, physical or chemical properties, which have been widely used in various modern industries and cutting-edge science and technology. Special ceramics usually have one or more functions, such as single functions such as electricity, magnetism, light, heat, sound, chemistry, and biology, as well as coupling functions such as piezoelectricity, pyroelectricity, electro-optic, acousto-optic, and magneto-optic. The cornerstone of cutting-edge technologies such as aerospace, energy, machinery, electronic information and bioengineering. In the development of science and technology in the 21st century, the research on special ceramics has occupied a very important position.
