Abstract
A method of making chalcogenide glass which utilizes liquid encapsulation to prevent the evaporation loss of low boiling point or high vapor pressure glass components while the glass melt is being processed.
Claims35
A method of making chalcogenide glass, comprising the steps of:
- (a) placing about stoichiometric amounts of glass components into a reactor;
- (b) substantially covering the glass components in the reactor with an encapsulent;
- and
- (c) heating to a temperature sufficient to cause the glass components to react to form molten chalcogenide glass,
- wherein the encapsulent is not present in the chalcogenide glass.
2 more elements
A method of making chalcogenide glass, comprising the steps of:
- (a) placing about stoichiometric amounts of glass components, including at least a first glass component, into a reactor;
- (b) substantially covering the glass components in the reactor with an encapsulent;
- and
- (c) heating to a temperature below the boiling point of the lowest boiling point glass component,
- wherein the encapsulent is not present in the chalcogenide glass.

A method of making chalcogenide glass containing selenium, comprising the steps of:
- (a) placing about stoichiometric amounts of glass components, including selenium and at least a second glass component, into a reactor, wherein the second glass component has a melting point of at least about 600° C.;
- (b) substantially covering the glass components in the reactor with an encapsulent;
- and
- (c) heating to a temperature sufficient to cause the glass components to react to form molten chalcogenide glass,
- wherein the encapsulent is not present in the chalcogenide glass.

A method of making a ternary selenium-germanium-antimony chalcogenide glass, comprising the steps of:
- (a) placing about 50 mol % to about 98 mol % selenium, about 1mol % to about 40 mol % germanium and about 1 mol % to about 30 mol % antimony into a reactor;
- (b) substantially covering the selenium, germanium and antimony in the reactor with an encapsulent;
- and
- (c) heating the reactor to at least about 650° C. to cause the selenium, germanium and antimony to react to form molten chalcogenide glass,
- wherein the encapsulent is not present in the chalcogenide glass.
