text: # Dysprosium(III) oxide
  
  Dysprosium oxide $(Dy_2O_3)$ is a sesquioxide compound of the rare earth metal dysprosium. It is a pastel yellowish-greenish, slightly hygroscopic powder having specialized uses in ceramics, glass, phosphors, lasers, as a Faraday rotator and dysprosium metal halide lamps.
  
  It can react with acids to produce the corresponding dysprosium(III) salts:
  
      $Dy_2O_3$ + 6 HCl → 2 $DyCl_3$ + 3 $H_2O$
