Borate phosphate
Chemical compound
From Wikipedia, the free encyclopedia
Borate phosphates are mixed anion compounds containing separate borate and phosphate anions. They are distinct from the borophosphates where the borate is linked to a phosphate via a common oxygen atom. The borate phosphates have a higher ratio of cations to number of borates and phosphates, as compared to the borophosphates.[1]

Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa).

There are also organic esters of both borate and phosphate, e.g. NADH-borate.[2]
Production
In the high temperature method, ingredients are heated together at atmospheric pressure. Products are anhydrous, and production or borophosphates is likely.[3]
The boron flux method involves dissolving ingredients such as an ammonium phosphate and metal carbonate in an excess of molten boric acid.[3]
Use
Borate phosphates are of research interest for their optical, electrooptical or magnetic properties.[3]
