Description
Summary:To evaluate, design, or characterize any thermo physical process such as drying, the homonymous properties of materials involved in such process are decisive. Until now, in researches carried out on drying lateritic mineral, properties that are not specifically of this material have been used, therefore, in the present study its specific heat is established for temperature ranges between 20ºC to 100ºC and moisture concentrations of 3% and 37%. To this purpose, experimental technique called differential scanning calorimetry was used, in which it was obtained that the specific heat varies between 0.459 and 0.902 kJ / kg.ºC for sample with 3% humidity and 1.169 to 1.456 kJ / kg.ºC for samples with 37% humidity. In addition, equations that correlate the variation of specific heat as a function of temperature and humidity are established.
