Silicones - Essential Chemical Industry

Silicones are synthetic polymers with a silicon-oxygen backbone similar to that in silicon dioxide (silica), but with organic groups attached to the silicon atoms by C-Si bonds. The silicone chain exposes organic groups to the outside. Thus, despite having a very polar chain, the physical properties of silicones are similar to those of an alkane.

Silicon - Wikipedia

Silicon is a chemical element with the syol Si and atomic nuer 14. It is a hard, brittle crystalline solid with a blue-grey metallic lustre, and is a tetravalent metalloid and semiconductor.It is a meer of group 14 in the periodic table: carbon is above it; and germanium, tin, and lead are below it. It is relatively unreactive. Because of its high chemical affinity for oxygen, it was not

Silicon wafers, silicon wafer processing and related

Silicon wafers are generally not 100% pure silicon, but are instead formed with an initial impurity doping concentration between 1013 and 1016 atoms per cm3 of boron, phosphorus, arsenic, or antimony which is added to the melt and defines the wafer as either bulk n-type or p-type.

Czochralski method - Wikipedia

High-purity, semiconductor-grade silicon (only a few parts per million of impurities) is melted in a crucible at 1,425 °C (2,597 °F; 1,698 K), usually made of quartz.Dopant impurity atoms such as boron or phosphorus can be added to the molten silicon in precise amounts to dope the silicon, thus changing it into p-type or n-type silicon, with different electronic properties.

Silicon Monoxide - Properties and Evaporation Techniques

Silicon monoxide, SiO, is volatile at temperatures above 1100°C and can be readily vacuum deposited to form amorphous films with small grain size, high dielectric strength and good adhesion to glass. The films are not hygroscopic, are chemically stable at low oxygen pressures and temperatures below 200°C, and show good abrasion resistance.

Silicone Oil Explained: Weight (W or WT) Versus cSt - RC

Aug 12, 2016· While silicone oil is recognized as the best for RC due to its ability to resist changes in viscosity due to temperature fluctuations, the labeling can be misleading. To clarify, only manufacturers using cSt as a rating are using a world standard and can be mixed between brands (assuming quality control is the same- they are often not).
