Boron phosphate is aninorganic compound with thechemical formula BPO4. The simplest way of producing it is the reaction ofphosphoric acid andboric acid. It is a white infusible solid that evaporates above 1450 °C.[3]
Boron phosphate is synthesized fromphosphoric acid andboric acid at a temperature range from 80 °C to 1200 °C. The relatively cold treatment produces a whiteamorphous powder, which is converted to amicrocrystalline product when heated at about 1000 °C for 2 hours.[4]
The main reaction of the process is:
New ways of synthesizing the compound have also been reported, such ashydrothermal andmicrowave synthesis.[5]
Due to the particular industrial interest of boron phosphate, other methods are used as well:[5]
If obtained at pressure, the ordinary structure isisomorphous with the β-cristobalite, while subjecting it to high pressure is obtained a compoundisomorphic with α-quartz.[6] The structure of AlPO4,berlinite, isisomorphous with α-quartz.[3]
It is used as a catalyst fordehydration and other reactions inorganic synthesis. Also, it serves as a source of phosphates forexchange reactions in the solid state to obtain metal phosphates.[7]
