Holmium Sulfate is a moderately water and acid soluble Holmium source for uses compatible with sulfates. Sulfate compounds are salts or esters of sulfuric acid formed by replacing one or both of the hydrogens with a metal. Most metal sulfate compounds are readily soluble in water for uses such as water treatment, unlike fluorides and oxides which tend to be insoluble. Organometallic forms are soluble in organic solutions and sometimes in both aqueous and organic solutions. Metallic ions can also be dispersed utilizing suspended or coated nanoparticles (See also application discussion at Nanotechnology Information and at Quantum Dots) and deposited utilizing sputtering targets and evaporation materials for uses such as solar energy materials and fuel cells. Holmium has the highest magnetic moment (10.6 µB) of any naturally occurring element and has been used to create the highest known magnetic fields as a pole piece or magnetic flux concentrator. Holmium Sulfate is generally immediately available in most volumes. Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. Nanoscale (See also Nanotechnology Information and Quantum Dots) elemental powders and suspensions, as alternative high surface area forms, may be considered. We also produce Holmium Sulfate Solution. Additional technical, research and safety (MSDS) information is available as is a Reference Calculator for converting relevant units of measurement.

Holmium is a Block F, Group 3, Period 6 element. The electronic configuration is [Xe]4f116s2. In its elemental form holmium's CAS number is 7440-60-0. The holmium atom has a radius of 174.3.pm and it's Van der Waals radius is unknown. Holmium has the highest magnetic moment (10.6µB) of any naturally occurring element. Because of this it has been used to create the highest known magnetic fields by placing it within high strength magnets as a pole piece or magnetic flux concentrator. This magnetic property also has value in yttrium-iron-garnet (YIG) lasers for microwave equipment.
