Medida de tempo para o equilíbrio térmico em cristais de espoduménio

Américo Tsuneo Fuji, Sadao Isotani

Abstract


Experiments for measurement of time taken to reach thermal equilibrium in Spodumene crystals — 2mm to 5,4mm thick - in the temperature range 100° to 250°C are described. The measurements indicate a linear relationship between time and thickenes for heating as well as for cooling. Difference in thermal equilibrium time for heating and for cooling is about of 20 seconds.
