The "supercompressed" state of matter as an investigation object in high-pressure chemistry

The prospects of a new line of research in high-pressure chemistry are disc ussed, which is associated with investigations of chemical reactions accomp anied by large volume effects at ambient pressure and, hence, resulting in greater compressibilities of the reaction products. The compounds formed by intercalation of alkali metals in graphite and intermetallic compounds for med between alkali metals and silver or Group V metals (Sb, Pi), which crys tallize with the BiF3 structural type, are considered as examples of "chemi cal compression.".
