FAQ

What are the physical and chemical properties of Holmium trichloride (CAS: 10138-62-2)?

Holmium trichloride (CAS: 10138-62-2) is a trivalent trichloride of holmium, forming rhombohedral crystals. Its molecular weight is approximately 461.12 g/mol. It is slightly soluble in water and has a low reactivity with common reagents. It is stable under normal conditions but should be stored away from moisture and acids.

How is holmium trichloride (CAS: 10138-62-2) typically synthesized?

Holmium trichloride is typically synthesized by the reaction of holmium metal with chlorine gas at high temperatures. The reaction is catalyzed by an inert metal such as platinum. The selectivity and yield are high, and the product is purified by recrystallization from ethanol.

What industries use holmium trichloride (CAS: 10138-62-2)?

Holmium trichloride (CAS: 10138-62-2) is primarily used in the production of laser materials, phosphors, and as a dopant in semiconductors. It also finds applications in the development of magnetic materials and as a catalyst component in certain organic synthesis reactions.

What precautions should be taken when handling holmium trichloride (CAS: 10138-62-2)?

When handling holmium trichloride (CAS: 10138-62-2), it is essential to use appropriate personal protective equipment (PPE), including gloves, goggles, and a lab coat. Work should be conducted in a well-ventilated area or a fume hood. Spills should be cleaned up immediately using appropriate procedures, and the material should be stored in a dry, cool place away from moisture and acids. Always consult the Safety Data Sheet (SDS) for detailed handling instructions.
