Selenium - Wikipedia

2019-4-25 · Selenium is a chemical element with syol Se and atomic nuer 34. It is a nonmetal (more rarely considered a metalloid) with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium, and also has similarities to arsenic. It rarely occurs in its elemental state or as pure ore compounds

Silicon Carbide - an overview | ScienceDirect Topics

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. 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 use up to 1600 °C

Silicon - Element information, properties and uses

Silicon is also used to make silicones. These are silicon-oxygen polymers with methyl groups attached. Silicone oil is a lubricant and is added to some cosmetics and hair conditioners. Silicone rubber is used as a waterproof sealant in bathrooms and around windows, pipes and roofs.

2013-2-25 · typically 10 m/s. The mounted silicon cylinder is drained into the wire grid and thus cut into single wafers. The wire is either coated with diamond splinters or wetted with a suspension of abra-sive particles such as diamonds or silicon carbide grains, and a carrier (glycol or oil).

R&D Proposal

2002-2-15 · Silicon Carbide. Semi-insulating 4H-SiC has the intrinsic possibility of being a radiation hard particle detector. 4H-SiC has a large band gap (3.3 eV), e-h pair generation per 100 um per MIP (5100 e) and a low carrier density, which implies a low leakage current and high initial resistivity, as high as 1011 (cm. at room temperature.

Pink stones are also available from Brazil; but most of these stones have been heated from orange material. It will not be easy to find the red and deep pink colors; if the color is intense, expect to pay an expensive price per carat. Pastel pinks are also available. These rarer topaz colors generally are found in stones under ten carat sizes

Densifiion of a SiC-matrix by electrophoretic

With the aim to improve the properties of the SiC-matrix in a SiC f /SiC composite for fusion appliions, a new fabriion technique coining electrophoretic deposition (EPD) and polymer infiltration and pyrolysis (PIP) was introduced. By using EPD from a well-dispersed, aqueous suspension we were able to produce SiC green bodies with closely packed particles (>62%TD).
