Description:

Holmium is a moderately hard, silver-white metal that is relatively stable in the air. It reacts easily with dilute acids, but not with dilute or concentrated hydrofluoric acid (HF), since a protective surface layer made of HoF3 forms. Holmium is a very strong paramagnet above 133 K (–140 ° C or –220 ° F). At this temperature, the metal arranges itself antiferromagnetically and forms a spiral structure in the base plane. At 19 K (–254 ° C) the magnetic moments along the c-axis tilt about 10 ° from the base plane and form a conical ferrimagnetic structure.

Areas of application:

  • Railing construction
  • food industry
  • Beverage industry
  • chemistry
