The Bi 4 Ti 3 O 12 (BIT) is a well known ferroelectric ceramic within the family of so called Aurivillius phases. The present work shows that when bismuth (Bi 3+ , r = 0.96 A) is substituted by trivalent europium ( r = 0.95 A), a solid solution, Bi 4

Upon electrochemical reduction in a lithium cell, calcite-type FeBO3 gives an amorphous compound which can intercalate 3 Li per formula at 1.1 V, ending with metallic iron for full discharge to 0.9 V. The amorphous phase can be cycled reversibly at 1
