Process for producing microceramic tubes by radiation exposure of silicon-based polymers

摘要

A process for producing a SiC ceramic microtube, comprising the steps of oxidizing the surface of an organosilicon polymer to become infusible by exposure to an ionizing radiation, extracting the uncrosslinked central portion of the fiber with an organic solvent to make a hollow silicon polymer fiber, and firing it in an inert gas so that it acquires a ceramic nature.
