Bronze and brass ornamental work Bronze and brass ornamental work The use of bronze dates from remote antiquity. This important metal is an alloy composed of copper and tin, in proportion which vary slightly, but may be normally considered as nine parts of copper to one of tin. Other ingredients which are occasionally found are more or less accidental. The result is a metal of a rich golden brown colour, capable of being worked by casting — a process little applicable to its component parts, but peculiarly successful with bronze, the density and hardness of the metal allowing it to take any impression of a
Silicon-tin Silicon-tin Silicon-tin or SiSn, is in general a term used for an alloy of the form SiSn. The molecular ratio of tin in silicon can vary based on the fabrication methods or doping conditions. In general, SiSn is known to be intrinsically semiconducting, and even small amounts of Sn doping in silicon can also be used to create strain in the silicon lattice and alter the charge transport properties. Several theoretical works have shown SiSn to be semiconducting. These mainly include DFT-based studies. The band structures obtained using these works show a change in band gap of silicon with the
