The major issue is variable purity values due to variations in the purification processes. Purity can achieve 4N, but 6N purity is problematic. At present, best results reported by a major company for metallurgically refined material is boron < 0.5 ppmw (parts per million weight) and ...
material which finds its applications in electrical, mechanical, structural and ballistic fields. Because of its very highstrengthto density ratio, silicon carbide is ideal material for armor industries and is generally preferred for applications where protection from moderate threats is required. The ...

under salt stress Zhao Gengmao1,2,*, Li Shihui1,*, Sun Xing1,*, Wang Yizhou1 & Chang Zipan1 Silicon(Si) is the only element which can enhance the resistance to multiple stresses. However, the role of silicon in medicinal plants under salt stress is not yet understood. ...
Elemental silicon is a major player in modern electronics because it's an ideal semiconductor of electricity. When heated into a molten state, silicon can be formed into semi-conductive wafers, to serve as the base for integrated circuits (microchips). ...

Two-dimensional photonic crystals have been realized in many different material systems; here, we focus on the silicon platform as it is suitable for low-cost mass production [17]. The fabrication of a silicon photonic crystal typically starts with a material known as Silicon-On-Insulator (SOI)...
The term Silicon Valley refers to a region in the south San Francisco Bay Area. The name was first adopted in the early 1970s because of the region's association with the silicon transistor, which is used in all modern microprocessors.1The area is notable for the vast number oftechnology c...
