MIXTURE FOR PRODUCING TELLURITE GLASS (VERSIONS) Russian patent published in 2016 - IPC C03C6/04 

FIELD: chemistry.

SUBSTANCE: invention relates to chemistry and concerns compositions of mixtures for producing tellurite glass, which can be used in optics for making fibre-optic guides and planar optical waveguides used in optoelectronic devices visible, near and middle infrared ranges. Mixture for producing tellurite glass includes connection of tellurium and molybdenum compound or compound of tellurium and tungsten compound. As a compound of tellurium charge contains orto-tellurium acid, and as compound of molybdenum is ammonium tetrahydrate heptamolybdate at following ratio of components, wt%: ammonium tetrahydrate heptamolybdate is 10-52, orto-tellurium acid is rest, or that of tellurium compound, it contains orto-tellurium acid, and as tungsten compound is ammonium dodecawolframate decahydrate at following ratio of components, wt%: ammonium dodecawolframate decahydrate is 6-39, orto-tellurium acid is rest.

EFFECT: technical result is high optical transparency of glass in visible and near infrared spectral regions.
