We present new experimental results relating to the growth and evolution of sea ice. These show, in particular, that brine initially remains trapped in the interstices of the sea ice, only draining into the underlying ocean once the depth of the sea-ice layer exceeds a critical value. A general theory for convection within mushy layers is applied to develop a hypothesis for when brine drainage

Silicon windows have good transmission in the range from 1.2 to 7.0 µm, with little or no distortion of the transmitted signal. Silicon has an advantage over other IR materials due to its low density (about half that of Zinc Selenide or Germanium), making it ideal for
Used to straight face dress and form specific radii on the cutting surface of conventional abrasive (aluminum oxide and silicon carbide) grinding wheels. The Graff AdvantageThe performance of any dressing tool is dependant upon the quality of the diamond it contains.
Cree Inc., an innovator of lighting class LEDs, power and radio frequency (RF) semiconductors, and lighting products, has announced plans to spend as much as $1bn to increase its silicon carbide capacity. The CEO of Cree, Gregg Lowe, in announcing the company’s expansion, said it was Cree’s largest-ever investment to radically increase the supply of […]

The Chinese crystal and jade polishers discovered that sand on which a fire had been built kept its abrasive qualities much longer than ordinary sand. They were soon firing sand and charcoal in kilns to obtain larger quantities of the new abrasive, a form of silicon carbide.
Emeralds can be processed using ordinary silicon carbide grits, though they will need to be cushioned as they are quite prone to fracture. You can also effectively process rocks of different hardnesses at the same time -- say, Mohs 5 through 7 -- as long as you use the appropriate abrasives and techniques for the softer material.
1. The silicon atoms in semiconductors are bonded with oxygen atoms to form a crystal; in semiconductors the silicon is pure and thus forms the amorphous structure. 2. Silicon has no effect on the properties of glass and semiconductors. 3.
Plastic sheets and film are polymers that supply material for injection molding, machining, packaging, construction, electronics, signs, and other appliions. These materials resist corrosion and provide electrical insulation. Plastic film is thinner and more flexible
Silicon Carbide This synthetic silicon carbide (essentially moissanite with a high-iron content) comes from a steel blast furnace in Poland. The hardness is 9.5 and the individual crystals are razor sharp!
The people among the farthest from the semiconductor business know silicon carbide now, but don''t know it. It''s sold as the diamond simulant Moissanite . Exactly how they produce those clear, white crystals to cut into imitation diamonds when the chemically pure semiconductor is that off-yellow color is their trade secret.
