Applications of Silicones

The growing interest in volatile silyl-metal complexes for chemical vapor deposition reactions should also be mentioned. This technique is extremely useful for the preparation of silicide films in microelectronic devices. Further examples of applications of silicon-metal compounds are given in the appropriate sections. 

Many applications of silicon are found in integrated circuits and other semiconductor devices and include the following (see Chs. 13-16 on applications of CVD). 

Although germanium was the original semiconductor material in early experiments and production, it is now rarely used as such but mostly as an alloy with silicon.li l l l Some applications of silicon/ germanium are ... 

Although fabrics made from microfibres generally have a softer handle and better drape than those from conventional fibres, these properties can be further improved to a significant extent by the application of silicone softeners, the best results being obtained with aminofunctional polysiloxanes [491]. 

The conventional production method for SiC - the reaction of coke and sand (Acheson process) -does not involve soluble or fusible intermediates. For many applications of silicon carbide this fact is not necessarily a disadvantage, but for the preparation of ceramic composites such intermediates are required. 

We expect these micromachined sensors to become more and more important in the household industry, in many domestic applications of silicon pressure sensors, acceleration sensors, tilt sensors, infrared detectors and thermopiles, flow meters, as well as gas sensors and liquid constituent sensors.

Hydrophobicity loss and recovery in silicone rubbers has been extensively studied and reviewed in a few recent publications with numerous references.581,582 The ability to recover hydrophobicity after oxidation or contamination is considered as one of the important features determining the applicability of silicones in electrical and other outdoor insulation. The methods of studying of what is known as aging and recovery mechanisms are discussed. 

With the rapidly growing applications of silicones, it follows that there are concerns to be addressed regarding environmental aspects of the use of these materials. The stability of silicones has been and continues to be thoroughly...

The applications of silicon in the electronics industry are so important that the major part of this report will be devoted to the electrochemistry of the elemental silicon crystals used as semiconductors. In fact, the extremely efficient surface treatment of Si wafers needed for the construction of ultra large-scale... 

Other solid-state applications of silicon carbide include its use as an electroluminescent diode for use in sound recording equipment and photomultipliers and controllers. It has been studied as a reflective surface for lasers. By combining its excellent thermal conductivity and high electrical resistance, silicon carbide has also found application as an insulating material for integrated circuit substrates. 

Because of the important potential applications of silicon nitride, the use of low-cost starting materials, such as elemental silicon and liquid ammonia or amines, may be more effective than the existing chloride method. In earlier work, litis process was found to form silicon di-imide (Si(NH)2), but required purification steps to remove chloride.
