  • SUSTAINABLE SILICATES AND METHODS FOR THEIR EXTRACTION
    Publication number: 20240116766
    Abstract: Liquid silicate products derived from processed organic plant matter (112), such as rice hulls, have improved purity and properties for use in the production of higher purity amorphous silica compositions (180). The liquid silicate can be optically clear, can have a controlled ratio of silica to metal earth oxide components, and can have lower concentrations of undesirable contaminants such as aluminum, chloride, iron, sulfate, and titanium.
    Type: Application
    Filed: December 5, 2023
    Publication date: April 11, 2024
    Applicant: Pörner Ingenieurgesellschaft m.b.H.
    Inventors: Gerhard Bacher, Holger Henze, Dirk Fliegner, Christoph Manitz, Sebastian Grahl, William H. Mullee
