Abstract: Controlling negative thermal expansion (NTE) is an important topic in the study of NTE materials. Generally, a large magnitude of NTE with a wide NTE operation temperature window is preferable for applications of NTE materials,… read more here.

Abstract: We discovered that sintered bodies of Co3BO5 exhibit negative thermal expansion (NTE), despite positive expansion of the crystal lattice. Dilatometry results show that, at temperatures of 400–550 K, sintered bodies of Co3BO5 exhibit NTE. Synchrotron x-ray… read more here.
