  • Crystallization-free glass frit compositions and frits made therefrom for microreactor devices
    Patent number: 8252708
    Abstract: A borosilicate glass composition suitable for manufacturing microreactor glass frits includes 12-22 mol % B2O3=12-22; 68-80 mol % SiO2; 3-8 mol % Al2O3, 1-8 mol % Li2O, and one of 0.5±0.1 mol % ZrO2 and 1.1±0.5 mol % F. After sintering a glass frit having the borosilicate glass composition, the glass frit has a surface crystalline layer of 30 ?m or less or is amorphous throughout.
    Type: Grant
    Filed: March 8, 2012
    Date of Patent: August 28, 2012
    Assignee: Corning Incorporated
