In the solid state reaction method bismuth oxide (BiO) and iron oxide (FeO) in a 1:1 mole ratio are mixed with a mortar, or by ball milling and then fired at elevated temperatures. The volatility of bismuth and the relatively stable competing ternary phases BiFeO (sillenite) and BiFeO (mullite) makes the solid state synthesis of phase pure and stoichiometric bismuth ferrite challenging.
Other historical antecedents of series elements include Hadrian’s Wall (which becomes Martin’s Wall), the legend of Atlantis (ancient Valyria), Byzantine Greek fire ( wildfire ), Icelandic sagas of the Viking Age (the Ironborn), the Mongol hordes (the Dothraki), the Hundred Years’ War (1337–1453) and the Italian Renaissance (c. 1400–1500).

When molten rock containing magnetic material, such as hematite (FeO), cools and solidifies in the presence of a magnetic field, it becomes magnetized and takes on the polarity of the background field.
The ancestors of the Ulpii were Roman colonists in Hispania. Little is known of them except that they were connected with a family of the Aelii, who had also settled in Hispania; Trajan’s aunt was the grandmother of the emperor Hadrian.
