Chemical synthesis and microstructure of nanocrystalline RB 6 (R = Ce, Eu)

Amorphous Europium Hexaboride: A Potential Room Temperature Formaldehyde Sensing Material

“…EuB 6 (Table S1) − is typically prepared by carbothermal reduction of europium oxide (Eu 2 O 3 ) and boron carbide (B 4 C) at 1650 °C, in vacuo, or by reduction of EuO with B in vacuum at 1400 °C . However, the extremely high reaction temperatures required makes these methods highly energy-intensive, and hence, there is a need to develop low-temperature methods for preparation of EuB 6 .…”
