一般描述

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.

应用

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 Ca6.2Mg3.8Sn with an unprecedented type of tin chain composed of square-planar tin units.
  • A catalyst in the highly selective oxidation of phenols.

The emergence of jawed vertebrates (gnathostomes) from jawless vertebrates was accompanied by major morphological and physiological innovations, such as hinged jaws, paired fins and immunoglobulin-based adaptive immunity. Gnathostomes subsequently diverged into two groups, the cartilaginous fishes and the bony vertebrates.
