A method for vitrifying waste to prevent the formation of molybdate secondary phases includes forming a feed mixture that includes the waste, a source of vanadium, and at least one of glass frit or glass forming chemicals and vitrifying the feed mixture in a melter to produce a glass product that includes the waste.

Method for vitrification of waste

The present invention provides compositions and methods for converting hazardous waste glass into safe and usable material. In particular, the present invention provides compositions and methods for producing ceramic products from toxic-metal-containing waste glass, thereby safely encapsulating the metals and other hazardous components within the ceramic products.

Compositions and methods for converting hazardous waste glass into non-hazardous products

A method for vitrification of waste to reduce the formation of persistent secondary phases comprising separating at least one glass frit constituent from an initial glass frit to form a modified glass frit. The waste, modified glass frit, and the at least one glass frit constituent are mixed together with the modified glass frit and the at least one glass frit constituent being added as separate components. The resulting mixture is vitrified.

Mitigation of secondary phase formation during waste vitrification

A method for vitrification of high level waste to reduce the formation of persistent secondary phases comprising the steps of providing a high level waste for vitrification; providing a glass frit additive for mixing with said high level waste; redistributing selected constituents of said glass frit for mixing separately as raw chemicals with said high level waste; and, feeding said high level waste, said glass frit additive, and the redistributed glass frit constituents to a melter for vitrification of said high level waste so that formation of secondary phases is suppressed.
