Abstract
Over seventy compounds of transition metals with B group elements were prepared and oxidised in air to determine the temperature for a weight increase of 1mg cm −1over 4 h, which is a measure of the onset of terminal oxidation and has been designated Tp. A vast majority of the compounds was found to be highly resistant to thermal oxidation and to be stable up to temperatures of the order of their melting point. The results have been classified using the concept of a periodic table divide and its associated zone of influence.
