Berylliumacetylid Chemische Eigenschaften,Einsatz,Produktion Methoden

Chemische Eigenschaften

Red cubic crystal; hard and refractory; density 1.90 g/cm3; decomposes when heated above 2,100°C; reacts with water.

Physikalische Eigenschaften

Brick-red or yellowish-red octahedra. Uses: Nuclear reactor cores.

Verwenden

Beryllium carbide (Be2C) is used for the cores in nuclear reactors.

synthetische

Beryllium carbide is prepared by heating the elements beryllium and carbon at elevated temperatures (above 900°C). It also may be prepared by reduction of beryllium oxide with carbon at a temperature above 1,500°C:
2BeO + 3C → (1500℃)→ Be₂C + 2CO
Beryllium carbide decomposes very slowly in water:
Be₂C + 2H₂O → 2BeO + CH₄
The rate of decomposition is faster in mineral acids with evolution of methane. However, in hot concentrated alkalies the reaction is very rapid, forming alkali metal beryllate and methane:
Be₂C + 4NaOH → 2Na₂BeO₂ + CH₄
