Abstract

SiC films have been grown by a chemical vapor infiltration and deposition method. Different microstructures, so-called 'whisker-type' SiC films, have been fabricated, and the deposition and infiltration conditions of whisker growth have been studied. By connecting the SiC/C particles of the green body, fractural strength has been increased and, subsequently, the open pore structure of the body has been modified by an infiltrated whiskering process without a canning effect. Without using a metallic catalyst, silicon carbide whiskers have been obtained at an input gas ratio (H2/MTS) above 20, and at temperatures below 1200 °C. The microstructure and composition of the whiskered SiC have been investigated by means of SEM and XPS.
