Glass microspheres comprising sulfide, and methods of producing glass microspheres

摘要

A method for manufacturing a plurality of glass microspheres comprises: melting a batch into a first glass melt in a melter system, processing the first glass melt into a second glass, pulverizing the second glass into a plurality of glass fragments, thermally processing the plurality of glass fragments into a plurality of glass microspheres, providing at least one of a plurality of redox reactions and a plurality of events in at least one of the first glass melt and a melt of the second glass, and the plurality of redox reactions and the plurality of events are induced by a plurality of redox active group (RAG) components.

1. A method of producing microspheres, comprising:
melting a batch into a first glass melt; processing the first glass melt into a second glass comprising adding a gas to the first glass melt; pulverizing the second glass into a plurality of glass fragments comprising (i) sulfide and (ii) sulfate, and thermally processing the plurality of glass fragments into microspheres, wherein the thermally processing comprises heating to cause reaction of (i) the sulfide with (ii) the sulfate, to form SO2 gas, wherein the second glass has a melting temperature less than the first glass, and the gas comprises a sulfur containing compound.
