Effects of SiC nanofibers addition on microstructure and dielectric properties of lead titanate ceramics

Dielectric properties of PbTiO3/ZnO ceramic nanocomposites obtained by solid-state reaction method

“…A few studies have been conducted on ferroelectric matrix/metal nanodispersoid [14] and non-ferroelectric matrix/ferroelectric nanodispersoid [15]. PT ceramic-based composites have recently been developed to improve the mechanical and dielectric properties [16,17]. Silicon carbide (SiC) nanofibers and PT nanopowders have been employed as the reinforcement in the composites because of their ability to resist crack growth [18].…”

Dielectric properties of the SiC fiber-reinforced SiC matrix composites with the CVD SiC interphases

“…In addition, due to the excellent semiconductivity and relatively stable dielectric characteristics at high-temperature, SiC also has many practical and potential applications for microwave absorption [5][6][7][8][9][10][11][12][13][14]. However, due to the inherent brittle failure behavior of monolithic SiC ceramic, it has been gradually substituted by SiCf/SiC composites, which can significantly improve the properties of monolithic SiC ceramic [15][16][17].…”

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].…”
