DIFFERENTIAL THERMAL ANALYSIS OF SYNTHETIC MANGANESE DIOXIDES.

N S KRISHNA PRASAD, C C PATEL

Abstract


Differential thermal analysis of synthetic and natural modifications of MnO<sub>2</sub> samples has been carried out using Pt-Pt (13% Rh) thermocouples.It has been shown that the results obtained with Pt-Pt (Rh)thermo-couple are not reliable on account of the corrosion of Pt (Rh)alloy by the chemically prepared MnO<sub>2</sub> A method has been suggestedfor the application of corrections to overcome this difficulty in getting the thermal curves.
