Latest Patents

Among Paolo Cortesi's latest patents is one that revolves around alpha-alumina in the form of spherical non-aggregated particles. This invention features alpha-alumina characterized by specific attributes: solid, spherical particles ranging from 0.06 to 2 μm in diameter, with a polydispersion index below 2.0, total porosity less than 0.3 cc/g, a specific surface area from 0.7 to 80 m²/g, and an apparent density of 3.20 to 3.94 g/cm³. The preparation process involves an alpha-alumina precursor with specified moisture content and particle size, subjected to a meticulous heat-treatment that converts the precursor to phase alpha while maintaining particle integrity.

In addition, he holds a patent for an apparatus designed for the preparation of monodispersed, spherical, non-agglomerated metal oxide particles. This innovative device uses a two-stream gaseous approach to ensure that the temperature in the duct is maintained below the condensation temperature of the metal compound, leading to the optimal formation of hydrated metal oxides which are then calcined to the desired oxide form.
