boron phosphate hydrate - Nature
Open Data Verified Data
white tetragonal crystal or fine powder. Melting point> 1200 °c. Density 2.802g/cm3. Soluble in caustic metal solution, insoluble in water, ethanol, benzene, acetone, dilute acid. Anhydrous boron phosphate is a stable substance, non-hygroscopic. There are 1, 3, 4, 5, 6 Kinds of hydrate. Boron phosphate containing 1 molecule of crystal water is a white crystal, which is not deliquescent and soluble in water, and is dehydrated to BP04 by heating to above 400 ℃, and is converted into quartz-type boron phosphate at 32 ℃ and under high pressure. Boron phosphate and ammonia is not easy to form adduct, and six water soluble in liquid ammonia will form BP04-3H20.

boron phosphate hydrate - Preparation Method
Open Data Verified Data
phosphoric acid boric acid method is a more common production method. Phosphoric acid boric acid method can be divided into the following two processes.
- phosphoric acid and boric acid are mixed, and the reaction is carried out by heating at 80 to 100 ° C., or a phosphoric acid solution and a boric acid solution are mixed and then evaporated to dryness on a water bath. The amorphous material thus obtained was burned at 1000 ° C. For 2H. It was converted to crystalline boron phosphate. The boron phosphate prepared by the above reaction at 80 to 100 ° C. Is easily soluble in water; However, after strong heat (about 10 00 ° C.), it becomes a water-insoluble boron phosphate product.
- will 3. 44g of Crystalline boric acid was mixed with 6.44mol 85% Phosphoric acid in a molar ratio of P2 05:B203=0. 85-1, and then add 3.65g of ammonium phosphate in the ratio of (NH4)2 hpo4 I B2 03-0.5;1, in the obtained mixture, generally, the content is about P2 05 l B2 03=1.1 1 1, and 5g of formaldehyde solution is added at the same time, the corresponding molar ratio is CHzo ;B2 03=1.2:1, then, the mixture was added into a small thin-necked container made of polytetrafluoroethylene, stirred evenly, maintained at 150 ℃ for 24h, filtered, washed with distilled water, before 110 ℃, and then calcined at 300 ℃, finished crystalline boron phosphate

| production method | phosphoric acid-boric acid method is a more common production method. The phosphoric acid-boric acid method can be divided into the following two processes. Phosphoric acid and boric acid are mixed, heated at 80~100 ℃ for reaction, or phosphoric acid solution and boric acid solution are mixed and evaporated to dryness in a water bath. If the amorphous substance obtained in this way is burned at 1000 ℃ for 2 hours, it will be converted into crystalline boron phosphate. Boron phosphate prepared by the above 80~100 ℃ reaction is easily soluble in water; However, after strong heat (about 1000 ℃), it becomes a finished boron phosphate insoluble in water. Its H3BO3 + H3P04 → BPO4 + 3H2O mixes 3.44g of crystalline boric acid and 6.44 mol 85% phosphoric acid with a molar ratio of P2O5:B2O3 = 0.85:1, and 3.65g of ammonium phosphate is added with a ratio of (NH4)2HPO4:B2O3 = 0.5:l. in the obtained mixture, the content is generally about P2O5:B203 = 1.1:1, and 5g of formaldehyde solution is added at the same time, the corresponding molar ratio is CH2O:B2O3 = 1.2:1. Then, the above mixture is added into a small thin neck container made of polytetrafluoroethylene, stirred evenly, reacted at 150 ℃ for 24 hours, filtered, washed with distilled water, calcined at 110 ℃ and then calcined at 300 ℃ to obtain crystalline boron phosphate finished product. Its H3PO4 + H3B03 → BPO4 + 3H2O |
