  • Cylinder preparation for maintaining stability of stored materials
    Patent number: 9829152
    Abstract: Novel cylinder passivation procedures to increase the room temperature stability of gaseous tin deuteride (SnD4) are described. Incorporation of specific organic-containing materials, which when applied onto surfaces of a vessel and/or conduit extending therefrom, can increase the shelf life stability of thermodynamically unstable gases stored within such pretreated vessels.
