Boron phosphate is an inorganic compound with the chemical formula BPO4. The simplest way of producing it is the reaction of phosphoric acid and boric acid. It is a white infusible solid that evaporates above 1450 °C.〔Corbridge DEC 2013, ''Phosphorus: Chemistry, Biochemistry and Technology,'' 6th ed., CRC Press, Boca Raton, Florida, ISBN 978-1-4398-4088-7〕 ==Synthesis== Boron phosphate is synthesized from phosphoric acid and boric acid at a temperature range from 80 °C to 1200 °C. The relatively cold treatment produces a white amorphous powder, which is converted to a microcrystalline product when heated at about 1000 °C for 2 hours. The main reaction of the process is: :H3BO3 + H3PO4 → BPO4 + 3 H2O New ways of synthesizing the compound have also been reported, such as hydrothermal and microwave synthesis. Due to the particular industrial interest of boron phosphate, other methods are used as well:〔 *Phosphoric acid and triethyl borate *Triethyl phosphate and boron trichloride *Diammonium phosphate acid and borax heated to 1000 ° C *Boric acid and phosphorus pentoxide (hydrothermal) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Boron phosphate」の詳細全文を読む スポンサード リンク
