Description

Holmium is a rare earth metal element known for its exceptional magnetic properties and specific spectral characteristics. It is a critical material in advanced technology sectors where precise control over physical properties is paramount. This high-purity material is essential for manufacturers and research institutions in the fields of specialized optics, nuclear technology, and high-strength magnetic alloys.

Application

• Specialized Optical Components: Used as a dopant in yttrium-based crystals (YAG, YLF) to produce specific laser wavelengths for medical, military, and scientific equipment.
• Nuclear Industry: Employed in control rods for nuclear reactors due to its high neutron absorption cross-section.
• High-Strength Magnets: An alloying element in neodymium-iron-boron (NdFeB) magnets to improve coercivity and thermal stability for high-performance motors and generators.
• Colorants and Phosphors: Imparts sharp yellow and red colorations in glass, cubic zirconia, and specialty phosphors.
• Calibration Standards: Serves as a spectral calibration standard for optical spectrophotometers due to its sharp absorption bands.
• Solid-State Research: A key material in research involving magnetostrictive materials and quantum computing components.

Quality Control

Our holmium is produced and handled under strict quality management protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing purity and trace metal content, typically analyzed via Inductively Coupled Plasma Mass Spectrometry (ICP-MS) and other relevant techniques. Specifications can be tailored to meet research-grade, 99.9%, 99.99%, or 99.999% (5N) purity requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place. For long-term storage of fine powder forms, maintaining an inert atmosphere (argon or nitrogen) is recommended to minimize surface oxidation. Keep away from strong acids and strong oxidizing agents.
