Abstract: A heater assembly is disclosed herein. The heater assembly may comprise a tubular body. The tubular body may include a graphite core disposed in a heating path. The graphite core may be coated with an overcoat layer. The tubular body may include slits that may cut-off heat transfer between portions of the tubular body. The heater assembly may have a configuration comprising a plurality of heating rungs having a predominant portion disposed substantially perpendicular to an upper surface of the heater so that the predominant portion is disposed vertically. The heater assembly may include a flange at a first end and a lip at a second end. The heater assembly configuration provides a heater that exhibits reduced thermal stress and/or reduced CTE mismatch stress particularly compared to other designs.

Abstract: The present technology provides a devitrification agent for crucibles with improved efficiency over previous devitrification agents for use in various technological fields, including semiconductors and photovoltaic applications. The devitrification agent may include (a) barium, and (b) tantalum, tungsten, germanium, tin, or a combination of two or more thereof. The devitrification agent may be integrated into a crucible during construction, applied to the surface of a finished crucible, and/or added into the silicon melt used in crystal pull. The technology described herein, improves sag resistance and provides a devitrified surface for slower, more controlled dissolution of silica by liquid silicon melt during silicon crystal growth.

Abstract: A process for producing a silylated product comprises reacting a mixture comprising (a) an unsaturated compound containing at least one unsaturated functional group, (b) a silyl hydride containing at least one silylhydride functional group, and (c) a catalyst, optionally in the presence of a solvent, to produce a dehydrogenative silylated product, a hydrosilylated product, or a combination of a dehydrogenative silylated product and a hydrosilylated product, wherein the catalyst is chosen from a pyridine diimine cobalt dicarboxylate complex or a cobalt carboxylate compound, and the process is conducted without pre-activating the catalyst via a reducing agent and/or without an initiator or promoter compound. The present catalysts have been found to be active in the presence of the silyl hydride employed in the silylation reaction.
