Abstract
In the present work, the partial oxidation of boron carbide particles having average sizes of 10, 32 and 93µm was studied in air. Prior to the oxidation process, the oxidation reactions were investigated by differential thermal analysis (DTA) studies. The values of the enthalpy of oxidation reaction of B4C particles have been determined approximately −4216.35J/g, −1941.36J/g and −817.65J/g respectively. According to the DTA analysis results, B4C particles have been oxidized at selective temperatures 600, 650 and 700°C in the range between 10 and 120min. Results showed that temperature, time, particle size, and specific surface area of B4C particles influenced oxidation process, intensely.
