Lithium aluminum deuteride

Lithium aluminum deuteride, chemical formula AlD4Li, CAS number 14128-54-2, is also known as lithium aluminum deuteride hydride, presented as a powdered compound. It has a density of about 0.716 to 0.736 grams per cubic centimeter, a molecular weight of 41.98, a melting point of about 125 degrees Celsius, and shows good stability at room temperature and pressure. However, it is worth noting that lithium aluminum deuteride will undergo a violent chemical reaction when it comes into contact with water, so it is important to avoid contact with humid air, moisture or acidic substances. During the storage process, it should be ensured that lithium aluminum deuteride is in a normal temperature, airtight, dark, ventilated and dry environment, and it is recommended to use inert gas protection to ensure its stability and safety to the greatest extent.

Physical and chemical properties	deuterated Lithium Aluminum Hydride is a gray powder with a density of 0.716 g/cm. It is Stable under normal temperature and pressure, reacts strongly with water, avoids contact with humid air, acid, etc., and is stored under normal temperature, closed, dark, ventilated and dry inert gas.

1. Thermal stability

Lithium aluminum deuteride has high thermal stability. This means that at high temperatures, lithium aluminum deuteride can remain stable and is not prone to decomposition or deterioration. This property makes lithium aluminum deuteride have a wide range of applications in high temperature processes, such as the preparation of high temperature superconducting materials, nuclear fuel and so on. Lithium aluminum deuteride has a relatively small density, which makes it an advantage in some specific fields. In aerospace, for example, lightweight materials are essential to reduce the weight of aircraft and improve their performance. As a lightweight material, lithium aluminum deuteride can effectively reduce the weight of aircraft while ensuring strength and stability, thereby improving its flight efficiency.

2. Electrical conductivity

Lithium aluminum deuteride also has excellent electrical conductivity. Since aluminum and lithium are both metallic elements, they have excellent electrical conductivity. However, the addition of deuterium has no obvious effect on its electrical conductivity, which makes lithium aluminum deuteride have potential application value in electronic devices, circuits and other fields.

3. Radioactivity

Lithium aluminum deuteride is somewhat radioactive. Although its radioactivity is relatively weak, in some special application scenarios, this property may play an unexpected role. For example, in the medical field, radioactive materials can be used to prepare radiopharmaceuticals, perform radiation therapy, etc. The radioactive properties of lithium aluminum deuteride may provide new possibilities for its application in the medical field.
