title: Thermoanalytical properties of analytical grade reagents V. Sodium halates.
abstract: The thermoanalytical properties of sodium halates have been investigated by means of a derivatograph and a visual DTA instrument. The thermal decomposition of the compounds studied was found to proceed only in the melt phase to a measurable extent, while the corresponding sodium halides were being formed. For sodium chlorate the formation and decomposition of sodium perchlorate could also be observed. The comparison of the results of thermal investigations with results of X-ray measurements has shown that the ionic character of the chemical bonds is highest for sodium iodate and lowest for sodium chlorate.
