CALCIUM METAL |
Application: |
Due to its strong affinity for oxygen and sulphur is utilised as a cleanser for nonferrous alloys. As a deoxidiser, desulphuriser and decarburiser for various ferrous and nonferrous alloys, where it is implemented in the form of a stick or lump of metal. It is used as a alloying agent for aluminium, beryllium, copper, lead and magnesium alloys. Serves as a ‘getter’ for residual gases in vacuum tubes. Crystalline calcium is employed in the form of a very reactive free-flowing powder of 94 to 97% purity and contains 2.5% calcium oxide (CaO) and smaller amounts of magnesium and these impurities. It can be used to harden lead. |
