摘要：

High-density silicate sheets made up of five-membered rings with Me 4NOH molecules and K+ ions in the porelike interlayer space: This is the structure of the silicate PLS-1. When PLS-1 (left picture) was heated above 673 K under vacuum, the novel zeolite CDS-1 (right picture) was obtained as the result of topotactic dehydration-condensation reactions. CDS-1 is a pure silicate and thermally stable, and should therefore find a range of industrial uses.
