Natural abundance of Boron-10 (¹⁰B) in boron carbide (B₄C)
Assistant:
Natural Abundance of ¹⁰B in Boron Carbide (B₄C)
Natural isotopic background of elemental boron:
Natural abundance of ¹⁰B = 19.8%
Natural abundance of ¹¹B = 80.2%
When boron carbide (B₄C) is synthesized from natural boron raw materials, the isotopic proportion remains unchanged.
Therefore:
✅ The natural abundance of ¹⁰B in ordinary industrial-grade boron carbide is also 19.8%.
The standard industrial range is 19.7%～19.9%, and 19.8% is the conventional reference value.
