. The results of dielectric property show that the sample with 0.005 B has the largest values in ε′ and ε″ among the four samples due to the existence of the intrinsic defects. But the absence of the relaxation polarization leads to low values of all the samples. Key words: SiC powder; sol-gel; B dopant; dielectric property; Raman spectroscopy 1 Introduction Silicon carbide is often considered the most......
