hi i have a quation about the diference between the epdm and silicon gasket ? on the oder hand which of them is good for seeling on the compress? (meckanical parameter requred) thanks.
silicon and germanium
SILICON same as any other diode but with different characteristics
A silicon transistor is a transistor made of silicon.
Germenium and silicon are the examples of Semiconductors.
There are a few different types of solar panel, for example Polycrystalline, Mono-crystalline, Amorphous or Hybrid. Amorphous provides the best efficiency in low light conditions but does result in larger panel sizes.
The color of a solar panel does not affect its output. Output is affected by the structure of the silicon, with single crystaline cells being the best, then poly crystaline cells then thin film amorphous cells. Sierra Solar, the Solar Living Institute, Giam Real Goods are all excellent places for more info
name the different allotropes of silicon?
Silicate.
Opal is composed primarily of silica (silicon dioxide, SiO2) with varying amounts of water trapped within its structure.
Silicon allotropes can range from dark brown to black in appearance. Amorphous silicon appears as a dark brown powder or a shiny black solid, while crystalline silicon forms shiny, gray-colored crystals.
Glass is an amorphous (non-crystalline) material composed mostly of silicon dioxide. Plastic is a broad term for thousands of different polymers, which are manmade hydrocarbons. Some are crystalline, and some are not.
Amorphous silicon hasspecific gravity (or Specific Density) of 2.35Crystalline silicon (the stuff ICs are made out of) has specific gravity of 2.49Source: http://www.indicareer.com/entrance-exams/mht-cet/chemistry/Silicon-1.html
The structure of silicon dioxide consists of silicon atoms bonded to four oxygen atoms in a tetrahedral arrangement. These tetrahedra link together to form a three-dimensional network structure, resulting in a rigid and crystalline material. Silicon dioxide can exist in different forms such as quartz, amorphous silica, and glass, depending on the arrangement of its atomic structure.
No, silicon is a chemical element that is a major component of sand, while glass is an amorphous solid material typically made by heating sand and other ingredients. Glass can contain silicon along with other elements, but they are not the same thing.
According to SolarPanelCenter.net there are 4 types of solar panels, namely, Monocrystalline Silicon Panels, Polycrystalline Silicon Panels, String Ribbon Silicon Panels, and Amorphous Silicon Panels.
Glass is held together by intra-molecular forces, specifically covalent bonds between silicon and oxygen atoms in a network structure.
