Sodium aluminum hydride

Sodium aluminum hydride, also known as sodium tetrahydroaluminate with the formula NaAlH4, is a white crystalline chemical. Under certain conditions, it has unique chemical properties. When heated to 180 ° C, sodium aluminum hydride will undergo a decomposition reaction, releasing a lot of energy. With a relative density of 1.2, it can remain stable in dry air and is not easily affected by the environment. However, sodium aluminum hydride is extremely sensitive to moisture and proton-containing solvents. Therefore, special moisture-proof measures need to be taken during storage and use. Typically, in laboratory or industrial Settings, sodium aluminum hydride will be stored in well-sealed containers and placed in a dry, cool place.

Sodium aluminum hydride, chemical formula NaAlH4, is a typical aluminum hydride with significant activity and reaction rates. In view of its structural characteristics, safety must be strictly guaranteed during storage and transportation, and contact with air, water, etc., to prevent the risk of violent reactions.

In the field of scientific research, sodium aluminum hydride has attracted much attention because of its unique chemical properties. Its high Hydrogen storage density makes it an ideal hydrogen storage material. When hydrogen is needed to be released, sodium aluminum hydride can be hydrolyzed or pyrolyzed under specific conditions to release a large amount of hydrogen, thus showing a broad application prospect in the field of hydrogen energy.
