Caesium tetrafluoroaluminate(1-)(CAS: 138577-01-2)

Caesium tetrafluoroaluminate(1-) is a solid compound with a crystalline form. Its molecular weight is approximately 256.84 g/mol. It has limited solubility in water but is soluble in non-polar solvents. Chemically, it is highly reactive with common acids and is stable in air and moisture under normal conditions.

Caesium tetrafluoroaluminate(1-) is typically synthesized through the reaction of caesium fluoride and aluminium fluoride in a suitable solvent. Commonly, this involves the use of a reaction vessel under anhydrous conditions to prevent decomposition. The yield is usually around 85-90%, and the process is selective for the formation of the desired tetrafluoroaluminate complex.

Caesium tetrafluoroaluminate(1-) finds applications in the semiconductor industry, particularly in the production of high-performance thin-film transistors. It is also used in the development of sensitive sensors and as a component in certain polymers for specific electronic applications.

When handling Caesium tetrafluoroaluminate(1-), it is essential to wear appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. It should be stored in a fume hood to minimize exposure to air and moisture. In the event of a spill, use appropriate spill cleanup procedures, and the material safety data sheet (MSDS) should be consulted for specific handling instructions.
