Compression is a common densification method for solid-state materials, but the structural evolution of compressed non-equilibrium oxide materials such as glasses and zeolites remains somewhat elusive. Here, the authors show that siliceous zeolite single-crystals cold-compressed at 20 GPa yield permanently densified glassy silica, while cold-compressed siliceous zeolite powder and glassy silica are metastable.
