Özet
Aim The aim of this study is to synthesize of magnesium diboride using elemental magnesium (Mg) and elemental Boron (B) by mechanochemical method. Design & Methodology Magnesium diboride synthesis was carried out using elemental magnesium (Mg), and elemental boron (B).The products obtained were analyzed by using XRD and SEM-EDS. Originality Mg is an unstable element that can be easily oxidized. For this reason, MgB2, which has a stable structure, is thought to have an energy value that can be used in rocket fuels. Findings Optimum conditions are determined as follows: ball/powder mass ratio is 8/1, milling time is 7 hours, ratio of reactants are determined as 10% B excess and sinter process temperature is 650 degrees C. Conclusion After the production and purification steps, the yield was calculated as 87.1% and the calorific energy value of the obtained MgB2 was measured as 9.2 kcal/g. Declaration of Ethical Standards The author(s) of this article declare that the materials and methods used in this study do not require ethical committee permission and/or legal-special permission.
