Deuterated germane, also known as GeD2, is a stable isotope-labeled version of germane where the hydrogen atoms have been replaced by deuterium. Its CAS number is 7782-65-2. Here are some characteristics of deuterated germane:
Physical Properties:
Appearance: Deuterated germane is a colorless gas at room temperature and pressure.
Boiling Point: The boiling point of deuterated germane is slightly higher than that of germane (GeH4), due to the increased mass of deuterium compared to hydrogen. However, precise values might vary slightly.
Density: Deuterated germane has a higher density than germane because deuterium is heavier than hydrogen.
Chemical Properties:
Reactivity: Like germane, deuterated germane is a hydride and can react with air, water, and oxidizing agents. It is flammable and potentially explosive when mixed with air.
Decomposition: Upon decomposition, it may release toxic and corrosive fumes including hydrogen and germanium dioxide.
Uses:
Research: Used in scientific research and isotopic labeling studies.
Semiconductor Industry: Deuterated germane can be used in the semiconductor industry for doping and epitaxial growth, similar to its non-deuterated counterpart.
Handling and Storage:
Safety Precautions: Due to its flammability and potential toxicity, deuterated germane requires careful handling. It should be stored in a cool, dry, and well-ventilated area, away from incompatible substances and sources of ignition.
Personal Protective Equipment (PPE): Appropriate PPE should be used when handling this substance, including gloves, goggles, and a face shield.
