Abstract
Glass or ceramic products including glass optical waveguides are produced by a vapor phase oxidation process wherein .beta.-diketonate complexes of selected metals having significant vapor pressures at some temperature below their decomposition temperatures are vaporized, transported to an oxidation site in the vapor phase, and reacted in the vapor phase to form particulate metal oxide soot. After capture, this soot can be consolidated by sintering to form e.g. clear glass of a purity suitable for drawing into glass optical waveguide fiber.
