Abstract

We report that natrolite,Na 16 Al 16 Si 24 O 48 ·16H 2 O, a small pore auxetic zeolite can incorporate significant amounts of Argon under moderate pressure- and temperature conditions resulting in Na 16 Al 16 Si 24 O 80 ·16H 2 O·6Ar. This material has a ∼6.5% larger unit cell than natrolite at ambient conditions and its structure is related to Na 16 Al 16 Si 24 O 80 ·24H 2 O, an intermediate superhydrated natrolite referred to as para-natrolite. Argon insertion under pressure into auxetic frameworks such as natrolites is an important and overlooked confinement mechanism with potential applications and implications.
