Taupānga
Ko te dicalcium phosphate te konupūmā phosphate me te tātai CaHPO4 me tōna dihydrate.Ko te "di" prefix i roto i te ingoa noa ka puta na te mea ko te hanga o te HPO42– anion he tango i nga protons e rua mai i te waikawa phosphoric, H3PO4.Kei te mohiotia ano ko te dibasic calcium phosphate or calcium monohydrogen phosphate.Ka whakamahia te dicalcium phosphate hei taapiri kai, ka kitea i roto i etahi toothpastes hei maaka whakakorikori, he mea koiora.
