Holmium acetate is the acetate salt of holmium, with a chemical formula of Ho(CH3COO)3.
Holmium acetate can be obtained by dissolving holmium carbonate in acetic acid: [1]
Dissolving holmium oxide in acetic acid at a pH of 4 will form the tetrahydrate of holmium acetate (Ho2(CH3COO)6·4H2O):[2]
Holmium acetate hemihepthydate decomposes at 105 °C, forming into a hemihydrate, further decomposing at 135 °C into an anhydride. Further adding heat will form Ho(OH)(CH3COO)2, HoO(CH3COO) then Ho2O2CO3, forming holmium oxide at 590 °C.[3]
Holmium acetate is used in the manufacture of ceramics, glass, phosphors, metal halide lamps, and as a dopant in garnet lasers. It is also used in nuclear reactors to keep the chain reaction in check.[4]
