2016/1/15· A recent modern technique known as oxide-metal-oxide (OMO) sandwich was applied to prepare the samples containing 0, 0.5, 1, 1.5, and 2 wt.% calcium. The results of the intensive research studies clarify that the presence of the calcium in the aluminum intensifies the oxidation of the alloys and subsequently the thickness of the oxide layers.
It is a soft, silver-white, highly reactive metal. In the Periodic table it is in column 1 (alkali metals), and shares with the other six elements in that column that it has a single electron in its outer shell, which it readily donates, creating a positively charged atom - a ion. Its only stable isotope is 23Na.
