Calcium formate is shown to be more readily absorbed form of calcium than calcium carbonate and calcium citrate. [7] No optic nerve damage has been observed with calcium formate supplementation – along with formaldehyde , formate is a major metabolic product of methanol , which can cause blindness upon ingestion.

Calcium is a chemical element; it has symbol Ca and atomic number 20. As an alkaline earth metal, calcium is a reactive metal that forms a dark oxide-nitride layer when exposed to air. Its physical and chemical properties are most similar to its heavier homologues strontium and barium.
Calcification is the accumulation of calcium salts in a body tissue. It normally occurs in the formation of bone, but calcium can be deposited abnormally in soft tissue, [1] [2] causing it to harden. Calcifications may be classified on whether there is mineral balance or not, and the location of the calcification. [3]
Calcium-60 is the heaviest known isotope as of 2020. [1] First observed in 2018 at Riken alongside 59 Ca and seven isotopes of other elements, [ 26 ] its existence suggests that there are additional even- N isotopes of calcium up to at least 70 Ca, while 59 Ca is probably the last bound isotope with odd N . [ 27 ]
Calcium oxalate is a combination of calcium ions and the conjugate base of oxalic acid, the oxalate anion. Its aqueous solutions are slightly basic because of the basicity of the oxalate ion. The basicity of calcium oxalate is weaker than that of sodium oxalate, due to its lower solubility in water.
Dystrophic calcification can occur even if the amount of calcium in the blood is not elevated, in contrast to metastatic calcification, which is a consequence of a systemic mineral imbalance, including hypercalcemia and/or hyperphosphatemia, that leads to calcium deposition in healthy tissues. [2]
Powellite is a calcium molybdate mineral with formula CaMoO 4. Powellite crystallizes with tetragonal – dipyramidal crystal structure as transparent adamantine blue, greenish-brown, yellow-to-grey typically anhedral forms. It exhibits distinct cleavage, and has a brittle-to-conchoidal fracture.
