Obtaining biomorphic ceramicas of sic from resources marine. (Machine-translation by Google Translate, not legally binding)

摘要

This invention deals with the obtaining of biomorphic silicon carbide (sic) ceramic materials from precursors of marine origin, such as algae, plants or sponges. With this it is possible to obtain porous materials with a wide range of microstructures offered by the marine environment since it has a great biodiversity, until now unexplored in this field of application. The manufacturing method consists of the following stages: A) selection and drying of the marine precursor B) controlled pyrolysis in an inert atmosphere C) molding of the carbonaceous preform D) infiltration with silicon in vacuum E) obtaining sic ceramics.
