Abstract: A method of capturing soot includes the steps: combusting a first precursor in a burner to produce a soot stream, the soot stream comprising soot and exiting the burner at an outlet; and directing a capture medium to the soot stream, the capture medium contacting the soot in an impact region, the soot having a temperature greater than 50° C. in the impact region.

Abstract: Methods and apparatuses for forming optical preforms from silica glass soot are disclosed. According to one embodiment, a method for forming an optical preform may include loading silica glass soot in a mold cavity of a mold body. The mold body may be rotated at a rotational speed sufficient to force the silica glass soot towards an inner wall of the mold body. Thereafter the silica glass soot is compressed in an inward radial direction as the mold body is rotated to form a soot compact layer.

Abstract: A process for modifying a surface of a cast polycrystalline silicon sheet to decrease the light reflectance of the cast polycrystalline sheet is disclosed. The cast polycrystalline silicon sheet has at least one structural feature resulting from the cast polycrystalline silicon sheet being directly cast to a thickness less than 1000 micrometers. The process comprises grit blasting the surface of the cast polycrystalline silicon sheet to give an abraded surface on the cast polycrystalline silicon sheet. The process further comprises chemically etching the abraded surface of the cast polycrystalline silicon sheet to give a chemically-etched, abraded surface. The light reflectance of the chemically-etched, abraded surface is decreased in comparison to the light reflectance of the surface of the cast polycrystalline silicon sheet before the step of grit blasting.
