  • Patent number: 11180415
    Abstract: Described are cementitious reagent materials produced from globally abundant inorganic feedstocks. Also described are methods for the manufacture of such cementitious reagent materials and forming the reagent materials as microspheroidal glassy particles. Also described are apparatuses, systems and methods for the thermochemical production of glassy cementitious reagents with spheroidal morphology. The apparatuses, systems and methods make use of an in-flight melting/quenching technology such that solid particles are flown in suspension, melted in suspension, and then quenched in suspension. The cementitious reagents may be combined with Portland cement and an alkali activator to form a blended cement. The cementitious reagents can be used in concrete to substantially reduce the CO2 emission associated with cement production.

  • Patent number: 9714192
    Abstract: Ion exchangeable glass compositions that develop concentration profiles and stress profiles that have higher magnitudes of concentration and compressive stress profiles than those provided by the error function (erfc)-shaped compressive stress profile for similar surface concentrations of stress-inducing components such as K+ or K2O and stresses. The advantaged stress profile is the result of a glass composition that is low in K2O (or potassium) in the base glass prior to ion exchange. A glass comprising lower amounts of K+ or K2O has a stronger dependence of diffusivity on concentration, leading to a non-erfc-shaped concentration profile. Several glass compositions that contain low amounts of K+ or K2O exhibit this beneficial effect, whereas other glasses containing higher amounts of K+ or K2O do not exhibit this effect.

  • Patent number: 9643882
    Abstract: Borosilicate glasses, preferably for use in the pharmaceutical sector, are provided. The borosilicate glasses are outstandingly suitable for the use as pharmaceutical primary packaging, such as phials or ampoules, since the aqueous or water-containing medicaments kept in the containers do not attack the glass significantly, and so the glass releases no, or only few, ions. The borosilicate glasses have the following composition in % by weight or consist thereof: SiO2 71-77; B2O3 9-12; Al2O3 5.5-8; Na2O 6-8; K2O 0.1-0.9; Li2O 0-0.3; CaO 0-1.5; BaO 0-1; F 0-0.3; Cl- 0-0.3; and MgO + CaO + BaO + SrO 0-2.

  • Patent number: 9365446
    Abstract: Methods for processing glass using select wavelength radiation in a convective environment, broadly referred to as “Local Temporary Annealing”, “LASER Edge Strengthening” and “LASER Enhanced Thermal Strengthening.” Local Temporary Annealing allows strengthened glass to be brought to a neutral stress state so daughter units can be cut from strengthened glass and other processes usually only performed on annealed glass. LASER Edge Strengthening allows surface compression to be thermally imparted to the edges of a whole sheet or daughter units cut from annealed glass, or modification of residual edge stress profiles in strengthened glass to produce stable, strengthened edges. LASER Enhanced Thermal Strengthening allows surface compression to be imparted to a sheet of annealed glass whilst maintaining reduced surface temperatures so the glass has superior geometric stability and surface compression can be imparted at levels not conventionally possible.

    Abstract: Intermediate to high CTE glass compositions and laminates formed from the same are described. The glasses described herein have properties, such as liquidus viscosity or liquidus temperature, which make them particularly well suited for use in fusion forming processes, such as the fusion down draw process and/or the fusion lamination process. Further, the glass composition may be used in a laminated glass article, such as a laminated glass article formed by a fusion laminate process, to provide strengthened laminates via clad compression as a result of CTE mismatch between the core glass and clad glass.
