Negative thermal expansion materials † [PDF]

open access: yesJournal of the Chemical Society, Dalton Transactions, 1999
The ZrW2O8 family of materials has been shown to exhibit the unusual property of negative thermal expansion over a wide temperature range. α-ZrW2O8 itself shows negative thermal expansion from 2 K to 1443 K with a coefficient of thermal expansion α1 of -9.1×10-6 K-1 between 2 and 300 K. This behaviour can be related to the unusual structure of these
