| Potassium tetrafluoroborate Usage And Synthesis |
| Chemical Properties | It appears as white powder or gelatinous crystals. It has hygroscopicity with bitter taste. It is slightly soluble in water and hot ethanol, insoluble in cold ethanol. |
| Application |
|
| Preparative Methods | Fluoroboric acid-potassium hydroxide method: Hydrofluoric acid and boric acid are sent into the reactor at a ratio of 25: 6.2 (weight ratio); the temperature does not exceed 40 ℃. The reaction continues for 6h. The prepared fluoroboric acid is fed to a neutralization tank and neutralized with a 5 mol/L potassium hydroxide under stirring and cooling (until the methyl orange is discolored). Precipitated potassium fluoroborate crystal is subject to centrifugal separation, washing and drying, obtaining the finished product of potassium fluoroborate. its 4HF + H3BO3 → HBF4 + 3H2O HBF4 + KOH → KBF4 + H2O Fluoroboric acid/potassium carbonate neutralization method: under the stirring of the coating container, apply the saturated potassium carbonate solution for neutralizing fluoroboric acid to until the methyl orange is discolored. The precipitated potassium fluoroborate is subject to centrifugal separation, washing and drying, obtaining the finished product of potassium fluoroborate. Its reaction is: 2HBF4 + K2CO3 → 2KBF4 + H2O + CO2 ↑ |
| Chemical Properties | white odourlesss crystalline powder |
| Uses | Has been proposed as a flux for soldering and brazing; filler in resin-bonded grinding wheels. |
| Uses | Potassium tetrafluoroborate is used as an active filler in the preparation of resin-bonded abrasives. It is also used for extraction, refining and processing of metals in the chemical industry. It finds application as additive in alloying industry and welding agent. Further, it is used in the production of fluxing agents for brazing and soldering. |
| Hazard | Toxic by ingestion. |
| Flammability and Explosibility | Notclassified |
| Safety Profile | Poison by intraperitoneal route. When heated to decomposition it emits very toxic fumes of F, K2O, and BOx. Used in sand casting of aluminum and magnesium, grinding, and in resinoid grindmg wheels. See also FLUORIDES and BORON COMPOUNDS. |
| Purification Methods | Crystallise it from H2O (solubility% (temperature): 0.3 (3o), 0.45 (20o), 1.4 (40o), 6.27 (100o), and dry it under vacuum. It is a non-hygroscopic salt. A 10% solution is transparent blue at 100o, green at 90o and yellow at 60o. [V.rlander et al. Chem Ber 65 535 1932, Kwasnik in Handbook of Preparative Inorganic Chemistry (Ed.
