Aluminum Sulfide (Al2S3) is an inorganic compound composed of aluminum and sulfur. It is known for its high reactivity, especially with water, and finds use primarily in chemical research and as an intermediate in certain chemical syntheses. Al₂S₃ is also used as a precursor for producing hydrogen sulfide (H₂S) in laboratory settings.
Formula: Al₂S₃, composed of aluminum and sulfur atoms.
Crystal Structure: Aluminum sulfide has a layered crystal structure, typically forming a yellowish or gray solid.
Density: 2.02 g/mL (101 kPa, 25℃)
Melting point: 1100℃ (101 kPa)
Boiling point: 1500℃ (101 kPa)
Appearance: Yellow hexagonal crystal system with the smell of rotten eggs.
Chemical Synthesis: Aluminum Sulfide (Al2S3) is sometimes used as a source of hydrogen sulfide (H₂S) in laboratory synthesis, which is useful for certain analytical applications.
Research Material: Due to its reactive nature, it is mainly studied in research settings rather than in large-scale industrial applications.
Moisture Sensitivity: Aluminum Sulfide (Al2S3) must be handled in a dry environment and stored in airtight containers to avoid its reaction with moisture.
Toxicity: The hydrolysis of Al₂S₃ produces hydrogen sulfide gas (H₂S), which is toxic, flammable, and has a characteristic foul odor. Proper ventilation, such as a fume hood, is necessary when handling this material.
Protective Equipment: Handling Al₂S₃ requires gloves, eye protection, and respiratory protection in some cases, to avoid exposure to both the compound and its byproducts.
Airtight, Moisture-Proof Containers: Aluminum Sulfide (Al2S3) should be stored in tightly sealed containers, ideally in a desiccator or inert atmosphere, such as nitrogen or argon.
Cool, Dry Environment: Keeping Al₂S₃ in a cool, dry location prolongs its stability by preventing unwanted reactions with air moisture.
