Abstract: A method of treating a powder (P) made from cerium oxide using an ion beam (F) in which: —the powder is stirred once or a plurality of times; —the ions of the ion beam are selected from the ions of the elements of the list consisting of helium (He), boron (B), carbon (C), nitrogen (N), oxygen (O), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe)—the acceleration voltage of the ions of the beam is between 10 kV and 1000 kV; —the treatment temperature of the powder (P) is less than or equal to Tf/3; —the ion dose per mass unit of powder to be treated is chosen from a range of between 1016 ions/g and 1022 ions/cm2 so as to lower the reduction temperature of the powder made from cerium oxide (P).

Abstract: A method of treatment using a beam of singly- and multiply-charged gas ions produced by an electron cyclotron resonance (ECR) source of a glass material in which —the ion acceleration voltage of between 5 kV and 1000 kV is chosen to create an implanted layer of a thickness equal to a multiple of 100 nm; —the ion dose per surface unit in a range of between 1012 ions/cm2 and 1018 ions/cm2 is chosen so as to create an atomic concentration of ions equal to 10% with a level of uncertainty of (+/−)5%. Advantageously this makes it possible to obtain materials made from glass that is non-reflective in the visible range

Abstract: A treatment method of a sapphire material, said method comprising bombardment of a surface of the sapphire material, said surface facing a medium different from the sapphire material, by a single- and/or multi-charged gas ion beam so as to produce an ion implanted layer in the sapphire material, wherein the ions are selected from ions of the elements from the list consisting of helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), boron (B), carbon (C), nitrogen (N), oxygen (O), fluorine (F), silicon (Si), phosphorus (P) and sulphur (S). Use of said method to obtain a capacitive touch panel having a high transmission in the visible range.
