Process for obtaining mono and polycrystalline silicon nitride fibers by synthesis technology self-propagating high temperature.

摘要

PROCEDURE FOR OBTAINING FIBER MONO AND POLYCRYSTALLINE SILICON NITRIDE SYNTHESIS THROUGH TECHNOLOGY self-propagating high temperature. PROCEDURE FOR OBTAINING AND FIBER MONO polycrystalline silicon nitride synthesis technology THROUGH self-propagating high temperature REACTION FROM NITROGEN GAS, at pressures between 5 and 30 MPA. (Megapascals), WITH SILICON METAL, with or without additives, without any application ENERGETICO EXTERNAL, once initiated the reaction. OBTAINED MONO AND LONG FIBER POLYCRYSTALLINE SILICON NITRIDE, with diameters between 0.1 and 10 microns and 100 microns and lengths from 30 mm and above.
