What is Potassium tetrafluoroborate?
Chemical properties
white odourlesss crystalline powder
The Uses of Potassium tetrafluoroborate
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.
The Uses of Potassium tetrafluoroborate
Has been proposed as a flux for soldering and brazing; filler in resin-bonded grinding wheels.
Hazard
Toxic by ingestion.
Flammability and Explosibility
Not classified
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.
