  Germanium monoxide (chemical formula GeO) is a chemical compound of germanium and oxygen. It can be prepared as a yellow sublimate at 1000 °C by reacting $GeO_2$ with Ge metal. The yellow sublimate turns brown on heating at 650 °C. GeO is not well characterised. It is amphoteric dissolving in acids to form germanium(II) salts and in alkali to form "trihydroxogermanates" or "germanites" containing the $Ge(OH)_3^−$ ion.
  
  ## Chemistry
  
  Germanium oxide decomposes to Ge and $GeO_2.$
