Recommended Features

Gadolinium has a silvery-white color and is moderately ductile. It becomes ferromagnetic below 17C, and near absolute zero, becomes superconducting. It is used for some electronics, high-temperature
Terbium has a silver-white color. It is a rare earth metal of the yttrium group and a member of the lanthanide series.
A hard and reactive metal, dysprosium has few uses. Its compounds can be used as catalysts in oil refining, and as components in some electronics. Near absolute zero, dysprosium is superconducting.
Holmium is a rare earth metal of the yttrium group and a member of the lanthanide series. It is silver in color made of hexagonal close packed crystals. It is one of the most paramagnetic sources know
Erbium is a metal with few uses. It is a grayish- silver color and can be used as an infrared absorbing glass and as an activator in some phosphorescent materials.
