The Quartz Page: Chemical Properties

The Si-O-Si bond linking two tetrahedra is not straight (180°), but forms an angle of 144° in quartz (Fig.5). As a result, the overall crystal structure of quartz is quite complex. In other silica modifiions this angle is different, while the angles inside the SiO 4 tetrahedra (defined by the O-Si-O bond) remain basically the same. The following table lists angles and distances for a few

Silicon Carbide SiC Material Properties

Silicon carbide is composed of tetrahedra of carbon and silicon atoms with strong bonds in the crystal lattice. This produces a very hard and strong material. Silicon carbide is not attacked by any acids or alkalis or molten salts up to 800°C. In air, SiC forms a protective silicon oxide coating at 1200°C and is able to be used up to 1600°C.

Chemistry for Kids: Elements - Silicon

Silicon has the relatively unique property for an element in that it expands when it freezes like water. It has a high melting point of 1,400 degrees Celsius and boils at 2,800 degrees Celsius. The most abundant compound in the Earth''s crust is silicon dioxide. Silicon Carbide (SiC) is often used as an abrasive and is nearly as hard as diamond.

Polysilicon - an overview | ScienceDirect Topics

A silicon wafer with insulated and conductive polysilicon vias is essentially like a standard silicon wafer for the device manufacturer. Typically, the process flow consists of through hole or blind hole preparation, insulation of the holes for example with thermal oxidation, the filling of the hole with polysilicon and final removal of the excess polysilicon ( Figure 39.4 ).
