By galvanic metal deposition, silicalite crystals have been embedded in silver or nickel foils; the resulting composites are self-supporting high-temperature membranes (thermally stable up to 650 K) and have been tested by permeation/pervaporation studies of a binary n-heptane–toluene mixture; a separation factor αtol/n-C7ca. 4 ± 1.5 is found over a wide temperature range.
