摘要： An improved sol-gel method is proposed for the preparation of a transparent silica gel block, in which a deposit of fine silica particles having a controlled particle diameter as prepared by hydrolyzing an alkoxy silane in the presence of ammonia is dispersed in a silica sol solution prepared in an acidic condition and settled therein to form a structure of closest-packing prior to gelation, drying, sintering and vitrification so that silica glass blocks can be obtained with low volume shrinkage from the wet gel in an improved yield without cracks, bubbles and haziness. The improvement can be further enhanced when two separately prepared deposits of silica particles having larger and smaller particle diameters are dispersed as combined in the silica sol solution, especially, when the particle diameter in one deposit is not exceeding 22.5% of that in the other deposit.

摘要： High transparency silica-titania glass beads are characterized by a linear transmittance of at least 70% as measured at a wavelength of 900 nm to 600 nm by a specific measurement method. Such beads are prepared by hydrolyzing and polycondensing a silicon alkoxide and a titanium alkoxide to form a silica-titania sol, converting the sol into a dry gel, and then grinding the gel followed by heating or heating the gel followed by grinding. A light transmisson epoxy resin composition comprising a curable epoxy resin, a curing agent, and the high tranparency silica-titania glass beads has crack resistance and high transparency in cured state. It is useful in encapsulating optical semiconductor devices.
