Primary silicon-based

Structures that come to mind for assignment to die observed spectra are those that would be expected from an initial disproportionation of two primary silyl radicals to a silene and a hydrosilane, followed by an addition of another silyl radical to the silene, producing a / silylated silyl radical. Repetition of the process would eventually lead to a highly sterically encumbered and undoubtedly persistent silicon-based radical carrying only silicons in its / positions ... [Pg.74]

These silicon-based polymers for coatings are usually primary linear chains of difunctional polysiloxane units with monofunctional end groups as follows ... [Pg.129]

Based on data from extensive past biological monitoring within the industry, urinary arsenic testing for silicon-based processing is of limited value. Its primary utility continues to be associated with gallium arsenide-based processing, particularly in maintenance activities. [Pg.218]

As the second most abundant element in the earth s crust (26-28%), silicon is vital to the construction industry as concrete and cement. The manufacture of silicon-based integrated circuits continues to evolve our computer-rich lifestyle. Most high-purity silicon is refined by conversion to ClsSiH or CUSi and distilled followed by reduction to elemental Si. These and other low-cost, high-purity materials serve as primary feedstocks for the manufacture of the diverse collection of silicon reagents used in organic synthesis. [Pg.841]

Because the Si in hot metal is rapidly oxidized to Si02 at the early of time in duplex converter process, almost all SiOa get into primary slag based on the Si oxidation ability. Silicon did not be remained in hot metal at the final stage of reaction, therefore Si02 was added into initial slag. The composition of hot metal was presented in the table 1. [Pg.200]

Hot corrosion is the term used for sodium-sulfate-induced corrosion. Components made of SiC and SigN4 form a layer of Si02 on their surfaces on exposure to oxidizing atmosphere. This thin layer acts as a protection that prevents the corrosion of the substrate. Previous works have shown that, for silicon-based ceramics, the primary mode of attack is dissolution of the silica scale [54-56]. [Pg.76]

Sinee there are very many different possibilities for varying organic groups within the molecule chains, there are many different products in the silicone marketplace with widely differing properties. The primary products which are produeed on a silicone base are silicone elastomers, silicone oils, which are... [Pg.116]

Although the primary function of sealants is to seal, adhesion promoters are often added, which allows them to adhere to the adjoining base materials. It is therefore sometimes difficult to distinguish between an adhesive and a sealant. For example, structural silicone adhesives are used in the building construction industry owing to their sealing, adhesive, elastomeric properties, and their resistance to harsh environmental conditions [67,70,77]. [Pg.700]

Canister anodes consist of a spirally wound galvanised steel outer casing containing a carbonaceous based extender which surrounds the primary anode element which may be graphite, silicon iron, magnetite, platinised titanium, mixed metal oxide-coated titanium or platinised niobium, etc. [Pg.163]
