Technical Aspects of Silicones

It is necessary that the discussion be confined to those organosilicon products which, on the basis of available information, show the greatest promise of widespread use. This would seem to mean the methyl, ethyl, and various alkyl-aryl silicone resins, methyl silicone oils and elastomers, and the methylchlorosilanes for water-repellent films. 

Future developments may change the relative emphasis on these materials.

Silicon nitride, oxynitride and silicon aluminium oxynitride (SiAlON) compounds are of considerable technical interest as advanced ceramics because of their stability and chemical inertness at elevated temperatures, and their excellent mechanical properties. Si MAS NMR has proved to be useful in studying various aspects of these compounds, including their formation and structure, the processes by which they are...

A final remark concerns the oxidation of silicon by reacting oxygen with silicon or polycrystalline silicon to form Si02—also performed in a furnace. Although technically the Si02 is directly thermally "grown" from the Si, this process is similar to LPCVD in many aspects. 

The increasing integration of different electronic systems requires new communication components which should not only suffice the technical requirements but should also take the economic aspect into consideration. Many communication systems are not inevitably dependent on very fast silicon semiconductor technology. A lot of tasks and applications can be managed with low complexity electronics. 

Technical alloys are usually of complicated composition. The aspects discussed so far show that the addition of aluminum, chromium, and/or silicon to the alloy composition can in particular be helpful for establishing protective oxide layers based on these elements. In order to form a continuous protective oxide scale of these elements in alloys that are based on other metals, first of all a minimum alloying concentration must be present. This situation has been dealt with in theory by Wagner (1952) and further de-...
