                                According to the U.S. National Institutes of Health, dicalcium phosphate dihydrate is also known as brushite. This compound, with the chemical formula $CaHPO_4·2H_2O$, is a hydrated calcium phosphate mineral that plays a role in both biological and industrial applications, from forming kidney stones and dental calculus to serving as a dietary supplement.
