Preparation

Barium carbide was first synthesized as an impure compound in the Soviet Union in 1986 by reducing Barium carbonate powder with metallic Magnesium in the presence of Carbon-14.[3] It can also be prepared by heating a Barium amalgam and Carbon powder mixture in a Hydrogen current. The pure compound is prepared by reducing Barium oxide with Carbon at a high temperature.[4]

Properties

Barium carbide reacts similarly to Calcium carbide,[5] but it's more fusible. When exposed to extreme heat, the Barium will evaporate leaving behind crystals of Graphite. It can also absorb the Carbon in a solution at high temperatures.[4]

Hazards

Barium carbide can cause damage to the GI tract and irritation in the skin and eyes[1]
