Beryllium carbide

Beryllium carbide 화학적 특성, 용도, 생산

• 화학적 성질

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

• 물리적 성질

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

• 용도

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

• 제조 방법

  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
