  • MILLED SILICA AND LIQUID RADIATION CURABLE COMPOSITIONS COMPRISING SAME
    Publication number: 20260201185
    Abstract: Fumed or precipitated silica milled in a first compressive milling step to a tapped density of 200%-1200% of the initial tapped density of the fumed or precipitated silica and milled in a second expansive milling step to a tapped density of 10% to 50% of the tapped density after the first compressive milling step.

  • PYROGENICALLY PREPARED SURFACE MODIFIED MAGNESIUM OXIDE
    Publication number: 20250326653
    Abstract: A pyrogenically prepared surface modified magnesium oxide finds application in electronics, catalysis, paints and oils and as cathode and/or anode active material coating for the production of cathodes and/or anodes in lithium-ion and sodium-ion batteries. In a process for the preparation of a pyrogenically prepared surface modified magnesium oxide, a surface modification and a thermal treatment at elevated temperatures adapts the physical and chemical properties of the magnesium oxide.

  • CATHODE ACTIVE MATERIAL PARTICLES ENCAPSULATED IN PYROGENIC, NANOSTRUCTURED MAGNESIUM OXIDE, AND METHODS OF MAKING AND USING THE SAME
    Publication number: 20250323245
    Abstract: A Process for producing a coated mixed lithium transition metal oxide starts with dry mixing of a mixed lithium transition metal oxide and a pyrogenically produced, nanostructured magnesium oxide in a mixing unit having a specific electrical power of 0.05-1.5 KW per kg of the mixed lithium transition metal oxide. The coated mixed lithium transition metal oxide finds application as an active positive electrode material for a lithium-ion battery, and electric and/or electronic devices.
