Abstract:
1. A fluid storage and dispensing vessel comprising an interior volume having disposed therein an adsorbent that is characterized by at least one of the following characteristics: (a) a fill density measured for arsine gas at 25° C. and pressure of 650 torr that is greater than 400 grams arsine per liter of adsorbent; (b) at least 30% of overall porosity of said adsorbent comprising slit-shaped pores having a size in a range of from about 0.3 to about 0.72 nanometer, and at least 20% of the overall porosity comprising micropores of diameter <2 nanometers; and (c) having a bulk density of from about 0.80 to about 2.0 grams per cubic centimeter, wherein said adsorbent is contained in said interior volume for sorptively retaining a fluid thereon and from which the fluid is desorbable for dispensing from the vessel, and further comprising said fluid contained therein, wherein the fluid comprises a fluid selected from the group consisting of hydrides, halides and organometallic gaseous reagents.
