  • Patent number: 6676858
    Abstract: Colorized fire retardants, and methods of making and using the same, are provided that include an uncolored or minimally colored fire retardant composition and a colorant. The colorant is an aqueous dispersion, slurry, or suspension that includes an insoluble, non-fugitive pigment, e.g., red iron oxide or titanium dioxide. The aqueous dispersion pigment is added to the uncolored or minimally colored fire retardant composition at a time proximate to discharging the retardant onto the fuel. Accordingly, a user has control over the type and amount of colorant added to the fire retardant composition.

  • Patent number: 6207024
    Abstract: A method of producing phosphorus in which a mixture of phosphoric acid and carbon reductant is exposed to microwaves at a power level sufficient to heat the mixture to a temperature at which phosphorous is produced. This method can be carried out at lower temperatures than conventional phosphorous production and does not give rise to the solid waste normally formed in conventional phosphorous production. The phosphorus thus formed can be converted back to phosphoric acid, thus effecting purification of the phosphoric acid.
