A solid silica‐based matrix containing 30 cm 3 of Kr (STP)/cm 3 of glass was prepared by sintering 96% SiO 2 with 28% porosity under 140 MPa krypton pressure. The glass was heated to 850° or 900°C and held at temperature until the glass density was ∼2 g/cm 3 . At 420°C, only 0.7% of the krypton would be released after one half‐life of 85 Kr (10.7 years). At T>600°C, release of krypton is accompanied by crack development, comminution, and glass softening. Advantages and disadvantages of this technique for radioactive gas storage and diffusion data are presented.
