More Information
Summary:Vitreous, algae growing materials, release stably ferrous ions, over long periods of time. The duration of ion release can be controlled as desired by adjusting the particle size of the materials. The vitreous, algae growing, materials can be converted into porous forms or fabricated into at least parts of structures. The vitreous, algae growing, materials consist essentially of 15 to 50 weight percent SiO2, 1 to 35 weight percent either or both of Na2O and K2O, 30 to 70 weight percent B2O3, and 1 to 40 weight prercent of either or both of FeO and Fe2O3. Increasing the content of boron facilitates the release of ferrous ions from the vitreous, algae growing, materials.
