Silicon carbide (SiC) is a well-known ceramic due to its excellent spectral absorbance and thermo-mechanical properties. The wide band gap, high melting point and thermal conductivity of SiC is used in high temperature applications. The present study was undertaken to investigate the effect of biofield treatment on physical, atomic, and structural characteristics of SiC powder. The control and biofield treated SiC powder was analysed using X-ray diffraction (XRD), particle size analyzer, surface area analyzer, and Fourier transform infrared (FT-IR) spectroscopy techniques with respect to control. The XRD pattern revealed that crystallite size was significantly increased by 40% in treated SiC as compared to control. The biofield treatment has induced changes in lattice parameter, density and molecular weight of atoms in the SiC powder. Particle size was increased upto 2.4% and the surface area was significantly reduced by 71.16% in treated SiC as compared to control. The FT-IR results indicated that the stretching vibrations frequency of silicon-carbon bond in treated SiC (925 cm -1 ) was shifted towards lower frequency as compared to control (947 cm -1 ). These findings suggest that biofield treatment has substantially altered the physical and structural properties of SiC powder.
