Uses & Applications

Applications and End-Uses for Holmium

Holmium (Ho) is a high-criticality rare earth element with annual global production of approximately 15 tonnes. Holmium possesses the highest magnetic moment of any naturally occurring element, making it useful in creating extremely powerful magnetic fields. Holmium lasers are widely used in medical procedures including lithotripsy and eye surgery. It is one of the least abundant rare earth elements and is produced exclusively as a co-product of other rare earth mining.

Key Applications

The primary end-uses of Holmium span multiple sectors. The following applications represent the most significant sources of global demand:

• Strongest permanent magnets - Holmium is valued in strongest permanent magnets for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Medical lasers for surgery - Holmium is valued in medical lasers for surgery for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Nuclear reactor components - Holmium is valued in nuclear reactor components for its unique physical and chemical properties that are difficult to replicate with alternative materials.
• Microwave equipment - Holmium is valued in microwave equipment for its unique physical and chemical properties that are difficult to replicate with alternative materials.

Product Forms and Specifications

Holmium is commercially available in 3 primary product forms, each serving different industrial requirements:

Demand Outlook

Holmium appears on both the USGS Critical Minerals List and the EU Critical Raw Materials List, underscoring its strategic importance across Western economies. Growing demand from electrification, digitalization, and defense modernization is expected to place additional pressure on the Holmium supply chain through the end of this decade.
