Appliion of electron beam curing for silicon carbide …

Abstract A SiC fiber was synthesized from polycarbosilane–polyvinylsilane (PCS–PVS) blend polymer with electron beam curing under vacuum. The SiC fiber obtained from the blend polymer which contains 20 wt% of PVS in PCS was very fine and flexible, and its average diameter was 7 μm. Although the yield of the SiC fiber from the blend polymer was 73%, that is lower than that of 82% from PCS

silicon - David Darling

Silicon (Si) is a dark-gray, metalloid (or semimetallic) element (see Figure 1), which is the second most abundant element in Earth''s crust (25.7% by mass). It occurs naturally in various forms, including minerals composed of silies and those, such as quartz, composed of silicon dioxide.

Introduction Silicon is th most abundant element after oxygen in the earth''s crust occuring mostly as the silies and quartz (SiO2). The other elements are acutally quite rare (~10-3 %) but tin an dlead are found in concetrated pockets of their ores (cassiterite, SnO 2 and galena, PbS 2) from which they are easily obtained, so they have been known and used since antiquity.

Carbosilanes are compounds in which the elements of silicon and carbon alternate in a molecular framework or polymeric backbone in an approximate ratio of 1:1. By appropriate selection of the carbosilane precursor and deposition conditions the silicon carbide framework can be shifted toward substituted silicon and diamond-like structures.
