摘要：

Sodium metavanadates in alpha (alpha-NaVO3), beta (beta-NaVO3) and hydrated (NaVO3 . 2H(2)O) forms were studied down to 10 K. All the phases were found to be stable at tow temperatures. The hydrated to beta transformation above room temperature was found to occur at 305 K. This transition is first order and most likely a one-step process, rather than a two-step process as had been suggested previously,
