Mass-dependent discrepancies in calcium isotope composition are conventionally expressed through the ratio of two isotopes (generally 44Ca/40Ca) in a sample in comparison with the exact same ratio in a normal reference content. 44Ca/40Ca differs by about 1% between prevalent earth materials.[33] Heritage
In addition to metallurgy, the reactivity of calcium is exploited to remove nitrogen from superior-purity argon gas and being a getter for oxygen and nitrogen. It is also applied to be a minimizing agent during the production of chromium, zirconium, thorium, vanadium and uranium.
