Beschreibung
Lead fluoborate is a nonflammable colorlessliquid or crystalline powder with a faint odor. Specific gravity (H2O:1) = 1.75 at 20℃; Molecular weight = 380.81.Hazard Identification (based on NFPA-704 M RatingSystem): Health 1, Flammability 0, Reactivity 0. Slightlysoluble in water (decomposes).
Chemische Eigenschaften
Lead fluoborate is a nonflammable colorless liquid or crystalline powder. Faint odor.
Verwenden
Used in tin-lead electroplatingLead(II) tetrafluoroborate is used as a catalyst involved in calixarene formation through hydrogen-bonded dimmers and in the preparation of linear polyesters. It is involved in the development and optimization of a bipolar lead-boron tetrafluoride accumulator. It is an electroplating solution for coating metal objects with lead and curing agent for epoxy resins. Further, it is used in printing lines, tin-lead alloy plating, lead soldering and also as a circuit board tin-lead alloy plating.
Verwenden
Catalyst for mediation of calixarene formation via hydrogen-bonded dimers

Analyzed in terms of electochemical characterization of the effects of impurities and organic additives in lead electrowinning from fluoroborate electrolyte

Used in the development and optimization of a bipolar lead-boron tetrafluoride accumulator
Allgemeine Beschreibung
Odorless colorless liquid. An aqueous solution. Sinks and mixes with water.
Reaktivität anzeigen
Solution is acidic and will corrode most metals [USCG, 1999]. Toxic and irritating hydrogen fluoride gas may form in fire [USCG, 1999].
Health Hazard
Early symptoms of lead intoxication via inhalation or ingestion are most commonly gastrointestinal disorders, colic, constipation, etc.; weakness, which may go on to paralysis, chiefly of the extensor muscles of the wrists and less often of the ankles, is noticeable in the most serious cases. Ingestion of a large amount causes local irritation of the alimentary tract; pain, leg cramps, muscle weakness, paresthesias, depression, coma, and death may follow in 1 or 2 days. Contact with eyes or skin may cause burns and/or irritation.
Brandgefahr
Special Hazards of Combustion Products: Toxic and irritating hydrogen fluoride gas may form in fire.
mögliche Exposition
This material is used in material finishing operations.
Erste Hilfe
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Antidotes and special procedures for lead: Persons withsignificant lead poisoning are sometimes treated with CaEDTA while hospitalized. This “chelating” drug causes arush of lead from the body organs into the blood and kidneys, and thus has its own hazards, and must be administered only by highly experienced medical personnel undercontrolled conditions and careful observation. Ca EDTA orsimilar drugs should never be used to prevent poisoningwhile exposure continues or without strict exposure control,as severe kidney damage can result.Note to physician: For severe poisoning BAL [British AntiLewisite, dimercaprol, dithiopropanol (C3H8OS2)] has beenused to treat toxic symptoms of certain heavy metals poisoning. In the case of lead poisoning it may have SOMEvalue. Although BAL is reported to have a large margin ofsafety, caution must be exercised, because toxic effects maybe caused by excessive dosage. Most can be prevented bypremedication with 1-ephedrine sulfate (CAS: 134-72-5).
Lager
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Lead fluoborate must be stored to avoid contactwith oxidizers (such as perchlorates, peroxides, permanganates, chlorates, and nitrates) and chemically active metals(such as potassium, sodium, magnesium, and zinc), sinceviolent reactions occur. A regulated, marked area should beestablished where this chemical is handled, used, or storedin compliance with OSHA Standard 1910.1045. Lead is regulated by an OSHA Standard 1910.1025. All requirementsof the standard must be followed.
