silicon does not exist as the pure metal and most commonly occurs in silica (including sand) and silicates. Silicon dioxide, also known as silica, is a hard substance with a high melting temperature and clearly very different from carbon dioxide. Molten silica can be used to make glass, an...
Beyond fundamental studies, there is much technological importance in silicon–oxygen phases with nanoscale structure—the interface between Si and SiO2 is essential in silicon metal-oxide semiconductors, and defects at this interface have been investigated for decades8,9,10. A material in the binary...
2.6.1.1 Silicon Metal Preparation and Applications Silicon metal, defined as at least 96% silicon content, became an important raw material starting in the 1940s with the development of aluminum alloys, silicone and silane chemical compounds, and high-purity polysilicon for electronics. Silicon metal...
Platinum (Pt) is a chemically noble transition metal (TM) with exceptional properties including the highest catalytic activity for oxygen reduction of any of the pure metals [1], a relatively high melting point of 1769 °C [2], and a yield strength that is low enough to be compatible with...
