Europium(III) chromate is a chemical compound composed of europium , chromium and oxygen with europium in the +3 oxidation state , chromium in the +5 oxidation state and oxygen in the −2 oxidation state.[4] [3] Eu Cr O 4
Preparation [ edit ]
To obtain europium(III) chromate, an equimolar solution of europium(III) acetate and chromium(IV ) oxide is dried in a vacuum at 70 °C and then heated to 400 °C in air.[2] [5] europium(III) nitrate hexahydrate and chromium(III) nitrate nonahydrate for 30 minutes at 433 K (160 °C; 320 °F), 30 minutes at 473 K (200 °C; 392 °F) and then 1 hour at 853 K (580 °C; 1,076 °F). A constant stream of oxygen is passed over the reaction mixture. An oxygen flow is used to stabilise the +5 oxidation state of chromium.[4]

Properties [ edit ]
Europium(III) chromate crystallizes tetragonally with space group I 4 1 /amd (No. 141) with lattice parameters a 1 ) and c 1 ) pm with four formula units per unit cell .[2]
The Néel temperature of europium(III) chromate is 15.9 K (−257.2 °C; −431.0 °F).[4] EuCrO3 ).[3]
