Fabrication of textured α-SiC using colloidal processing and a strong magnetic field

Abstract

In general, the mechanical and physical properties of a crystal depend on the direction of the crystal axis. The controlled development of the crystallographic texture in ceramics is very useful for improvement of their properties. The preparation of the textured SiC polycrystal was achieved by colloidal processing in a strong magnetic field. The c-axis of the SiC was parallel to the direction of the applied magnetic field. The bending strength of the textured SiC depends on the crack-growth direction. © 2007 The Japan Institute of Metals.
