Development of transparent polycrystalline beta-silicon …

Transparent beta-SiC is of great interest because its high strength, low coefficient of thermal expansion, very high thermal conductivity, and cubic crystal structure give it a very high thermal shock resistance. A transparent, polycrystalline beta-SiC window will find appliions in armor, hypersonic missiles, and thermal control for thin disc lasers. SiC is currently available as either

Improvement of piezoresistance properties of silicon …

Evaluation samples of alpha-silicon carbide ceramics were first fabried by glass capsule HIP method using powder mixture of silicon carbide and aluminum nitride with various ratios. The resultant aluminum nitride added silicon carbide ceramics were doped with nitrogen by changing the post-HIP nitrogen gas pressure.

Basic Parameters of Silicon Carbide (SiC)

Silicon carbide crystallizes in numerous (more than 200 ) different modifiions (polylypes). The most important are: cubic unit cell: 3C-SiC (cubic unit cell, zincblende); 2H-SiC; 4H-SiC; 6H-SiC (hexagonal unit cell, wurtzile ); 15R-SiC (rhoohedral unit cell).-SiC (rhoohedral unit cell).

IMPROVED TOUGHNESS OF SILICON CARBIDE

densified silicon carbide were formed in situ on fully sinterable silicon carbide-substrates. After final sintering, duplex silicon carbide structures resulted which were comprised of a fully sin tered, high density silicon carbide substrate or core, overlayed with an
