High Temperature Analysis of Dysprosium Rods
The growing movement toward alternative energy has cultivated a need for research into materials, most notably rare earth metals. Dysprosium is one such element that is becoming crucial for its utility in magnetic applications, due to its high magnetic moment. It is estimated that demand for dysprosium compounds (such as Dy2O3) will increase drastically and thus, a more thorough understanding of its behavior is critical for its sustainability. At room temperature, dysprosium is predicted to have an HCP crystal structure. However, preliminary analysis using x-ray diffraction and electron microscopy has revealed both FCC and BCC crystallographic phases present in cast dysprosium rods (99.9%) provided by two independent vendors being researched in this study. The high temperature behavior of dysprosium was investigated using differential scanning calorimetry and dilatometry. Previous results using cross sectional image analysis suggest linear oxidation behavior from 650-750 Celsius, and parabolic behavior from 800-900 Celsius.
