Chemical Information
FooDB NameCalcium diphosphate
Descriptioncalcium diphosphate, also known as ca2p2O7, belongs to the class of inorganic compounds known as alkaline earth metal pyrophosphates. These are inorganic compounds in which the largest oxoanion is pyrophosphate, and in which the heaviest atom not in an oxoanion is an alkaline earth metal. Based on a literature review a small amount of articles have been published on calcium diphosphate.
