1.5117 nm [13-14]. The α-SiC is chemically unstable and as a result their application is very
limited. A schematic showing the crystal structure of α and β−SiC is given in Figure 1.
The nano sized β-SiC particles were obtained from MER Corporation, USA. These
particles are spherical in shape with average diameter of about 30 nm as shown in Figure 2.
The bulk material contains more than 95% of SiC with small traces of Oxygen and Carbon.
