Chemical vapor deposition (CVD) silicon carbide resists corrosion in extreme environments while maintaining the high strength and excellent wear properties of silicon carbide. This capability, coined with the exceptional purity of 99.9995%, is helping make the ultra-clean manufacturing used in semiconductor production run faster and more efficiently.

Size: 1.5 ~ 20 mm, Weight: 30 pcs = around 25 g Silicon Carbide ( as known as Carborundum) does not occur naturally, it is man made from a coination of silica sand and carbon. This specimen reflects STRONG rainbow colors of greens, purples and blues and
Silicon Carbide Brick Appliion The silicon carbide brick is widely used in industry. It can be used for the inner lining of metallurgical steel tube, the nozzle, the plug head, the bottom and hearth of the blast furnace, the non water cooling rails of the heating furnace, the nonferrous metal smelting distiller, the tray of the distillation tower, the side wall of the electrolyzer, the
Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800 C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C. The high thermal conductivity coupled with low thermal expansion and high strength give this material exceptional thermal shock resistant qualities.

25/12/2013· For instance, "Silicon carbide exists in about 250 crystalline forms." But we can say that in all of these forms SiC exists as a network of alternating carbon and silicon atoms. Normally we think of CO2 as being nonpolar, with only London dispersion forces as the form of attraction between molecules.
Carborundum is a man made crystal coining silicon and carbon atoms fused together which sparkles in rainbow colours of gold, pink, green, blue and purple. Carborundum was originally sold as natural "rainbow hematite" and a few other rare crystals that look similar, but is increasingly being correctly known as a man-made silicon carbide.
Anisotropic Elasticity Hooke''s law describes the linear, isotropic relationship between stress (σ) and strain (ε) using compliance (S) and stiffness (C):σ=Cε , or ε=Sσ . The mechanical stiffness of materials under uniaxial loading is called the Young''s modulus, and is typically represented by the syol E in engineering texts, so Hooke''s law is often written as σ=Eε .
