说明

一般說明

Calcium is a highlyreactive and non-toxic metal that is widely used as a reducing agent. It isalso used for the improvement of steel, as a desulfurizer, and as an alloying agent. Calciumis prepared by the aluminothermal or electrolysis method.

應用

Ca₈Al₃ 和 Ca₁₃Al₁₄ 的前体；具有新金属性 Zintl 相的金属互化物。⁷

Calcium can be used as:

• Process control agent in mechanical alloying of titanium to get maximum powder yield and microstructural stability.
• A precursor to synthesize Ca₈Al₃ and Ca₁₃Al₁₄ with metallic Zintl phases and Ca_6.2Mg_3.8Sn with an unprecedented type of tin chain composed of square-planar tin units.
• A catalyst in the highly selective oxidation of phenols.
