  • Publication number: 20240199474
    Abstract: A transparent, chemically prestressable or chemically prestressed glass ceramic is provided. The glass ceramic has keatite as a main crystal phase, a transmittance greater than 80% at a thickness of 0.7 mm, a haze of less than or equal to 10, and a crystal phase content of at least 80% by weight of keatite solid solution based on all crystal phases in the glass ceramic.

  • Publication number: 20240199473
    Abstract: A transparent, chemically prestressable or chemically prestressed glass ceramic has a high transmittance, a low haze and a high crystal phase content of keatite solid solution. A method of making such a glass ceramic includes producing a silicate green glass with a melting process and subsequent hot shaping, temperature treating the silicate green glass with at least one nucleation step carried out in the temperature range of 690° C. to 850° C. for a period of 5 min to 72 h and at least one ceramization step carried out in the temperature range of 780° ° C. to 1100° C. for a period of 3 min to 150 h, and performing at least one ion exchange in an exchange bath at a temperature of the exchange bath between 370° C. and 500° ° C.

  • Publication number: 20210344039
    Abstract: The disclosure relates to an aluminum-doped lithium ion conductor based on a garnet structure comprising lanthanum, in particular an aluminum-doped lithium lanthanum zirconate (LLZO), in which the latter is co-doped with at least one trivalent M3+ ion on the lanthanum site, and in which the trivalent M3+ ion has an ionic radius that is smaller than that of La3+, and a higher lithium content is present in comparison to a stoichiometric garnet structure, with the provision that if M3+ is yttrium, a further trivalent M3+ ion, which is different than Y3+ and has an ionic radius that is smaller than that of La3+, is co-doped on the lanthanum site. A co-doping strategy is carried out, in which a doping on the lanthanum site with ions of the same valence, but smaller diameter brings about the change in the lattice geometry to the cubic modification. This leads to a stabilization of the cubic crystal modification that is present also with superstoichiometric quantities of lithium.
