Microwave dielectric properties of SiC(B) solid solution powder prepared by sol–gel

Review on the physicochemical treatments of rice husk for production of advanced materials

“…In the last decade, efforts have been made by various researchers to synthesize fine and pure SiC powder by alternative methods like sol-gel, plasma, laser, chemical vapor deposition (CVD), selfpropagatinghigh-temperature synthesis [229][230][231][232][233]. Nano-sized SiC rods have also been prepared using Si and C as the reactants at the temperature of 1200°C.…”

Fabrication and microwave absorbing properties of Ni–Zn spinel ferrites

“…The manufacture of microwave absorbing materials involves the use of compounds capable of generating dielectric and/or magnetic losses when impinged by an electromagnetic wave. Extensive study has been carried out to develop microwave absorbing materials with high efficiency and new absorption materials [1,[5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. By controlling the material type (dielectric or magnetic) and thickness, loss factor and impedances, and internal optical design, performance of the microwave absorbing material can be optimized for a single narrow band frequency, multiple frequencies, or over a broad frequency spectrum [23].…”

Mechanical and dielectric properties of porous Si3N4–SiC(BN) ceramic

“…Silicon carbide (SiC) is a good electromagnetic wave absorbing material [11][12][13][14], especially for nano-sized particles of SiC which are also useful for the improvement of mechanical and thermal properties of nanocomposite materials [15][16][17]. The relationship between dielectric behavior and interfacial polarization of nano-sized SiC materials has been studied [12,18,19], and the dielectric behaviors of nano-sized SiC doped with trace elements, such as B, N and Al, are much different from that of undoped nano-sized SiC [14,18,20,21].…”
