Neodymium arsenate, also known as neodymium(III) arsenate, is the arsenate of neodymium with the chemical formula of NdAsO4. In this compound, neodymium exhibits the +3 oxidation state. It has good thermal stability, and its pKsp,c is 21.86±0.11. [2]
Neodymium arsenate can be obtained from the reaction between sodium arsenate (Na3AsO4) and neodymium chloride (NdCl3) in solution: [3]
When crystallizing from a lead pyroarsenate flux, neodymium arsenate crystals produced explode when cooled. [4]
Neodymium arsenate also occurs in nature as a mineral. [5]
