Abstract
Official abstract text for this publication.
A process for making inorganic, metal oxide spheres that includes exposing solidified, molded microparticles that include a glass precursor composition to a temperature sufficient to transform the molded microparticles into molten glass and cooling the molten glass to form inorganic, metal oxide spheres.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for making inorganic, metal oxide spheres, the process comprising: forming a glass precursor composition comprising glass precursor particles dispersed in a vehicle such that the composition forms a dispersion, the vehicle including at least one of water, an organic liquid, and a binder; positioning the glass precursor composition in a plurality of mold cavities; solidifying the glass precursor composition in the plurality of mold cavities to f…
