Chemische Eigenschaften
white odourlesss crystalline powder
Verwenden
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.
Sicherheitsprofil
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.
läuterung methode
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. Brauer) Academic Press Vol I p 223 1963.]
