chemical element: Ca
( Granules )
High purity Calcium Metal Granules (99%).
Calcium is a chemical element; atomic number 20. Calcium metal reacts with water evolving Hydrogen gas and producing an alkaline Calcium Hydroxide solution. When ignited in air, Calcium metal burns with a bright white light, forming Calcium Nitride. In vacuum systems, small amounts of Calcium metal serves as a 'getter' for residual gasses. Calcium forms a thin white oxide layer on its surface that protects the metal from additional oxidation.
