Claim Text:
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 form solidified, molded microparticles; demolding the solidified, molded microparticles from the plurality of mold cavities; exposing the solidified, molded microparticles, after demolding, to a temperature sufficient to transform the molded microparticles into molten droplets; and cooling the molten droplets to form inorganic, metal oxide spheres.
