Potassium Fluoride
Chelora Chemicals supplies industrial-grade Potassium Fluoride (KF, CAS 7789-23-3), a water-soluble inorganic fluoride salt used as a fluorinating agent in organic synthesis, a flux additive in glass and ceramics processing, and a reagent in metal surface treatment. Export packing is engineered for the controlled handling fluoride salts require, moving in bulk from Indonesia to specialty chemical and metal-finishing buyers.
What Potassium Fluoride is, and why buyers source it
Potassium Fluoride supplies a reactive fluoride ion in a manageable, water-soluble crystalline form, making it a practical laboratory and industrial alternative to handling anhydrous hydrogen fluoride directly for many fluorination and flux applications.
KF dissociates cleanly in water and in polar aprotic solvents, releasing fluoride ion for nucleophilic fluorination reactions, halogen-exchange chemistry, and as a mild base/catalyst in organic synthesis routes.
In glass, ceramics and enamel formulations, Potassium Fluoride lowers melting points and improves surface flow, functioning alongside other fluoride fluxes to control opacity and finish.
How Potassium Fluoride is made
An overview of the production route for orientation purposes. Our manufacturing partners' own process parameters and in-process controls are proprietary and are not disclosed beyond what is needed to interpret the certificate of analysis.
Potassium Fluoride is manufactured by neutralising hydrofluoric acid (HF) with potassium carbonate or potassium hydroxide, followed by crystallisation and drying.
Reaction stoichiometry, crystallisation temperature and drying conditions are controlled to deliver a consistent, low-moisture, free-flowing product suitable for precise dosing in downstream reactions.
Industries and processes that use it
Potassium Fluoride's applications span organic fluorination chemistry and inorganic flux and surface-treatment uses.
Organic Fluorination
Nucleophilic fluorinating agent for halogen-exchange reactions in pharmaceutical and agrochemical intermediate synthesis.
Glass & Ceramics Flux
Melting-point depressant and flow modifier in specialty glass, enamel and ceramic glaze formulations.
Metal Surface Treatment
Component in fluxes and pickling formulations for aluminium brazing and selected metal-finishing processes.
Laboratory Reagent
General-purpose fluoride source for analytical and synthetic chemistry applications.
How the molecule is typically carried forward
Potassium Fluoride acts as a fluoride-ion donor, participating in substitution and flux-forming reactions depending on application.
Dissolution / Dispersion
KF is dissolved or dispersed in the target reaction medium or formulation.
Fluoride-Ion Action
Fluoride ion participates in nucleophilic substitution or lowers the melting/flow point of the glass or flux matrix.
Isolation / Finishing
Product isolation (organic synthesis) or cooling and finishing (glass/ceramics applications) completes the process.

Safety classification at a glance
Based on GHS classification as commonly listed for this substance. This is a summary for orientation only — always work from the current safety data sheet supplied with your specific batch.
Harmful if swallowed.
Harmful in contact with skin.
Harmful if inhaled.
Causes skin irritation.
Dust mask / respirator recommended for routine handling.
Safety goggles required.
Gloves recommended during handling.
Dry, cool, well-ventilated area, away from strong acids.
Potassium Fluoride is handled as a moderate-hazard inorganic salt. While less acutely hazardous than hydrofluoric acid itself, fluoride salts can cause irritation and systemic effects on prolonged or repeated exposure, so standard dust control, PPE and hygiene practices are followed throughout handling and packing.
Keeping it on spec between delivery and use
General storage guidance for this grade. Site-specific storage rules, segregation requirements and re-test intervals should follow your own EHS procedures and the MSDS issued with your batch.
Store in tightly sealed, moisture-resistant containers away from strong acids. Avoid contact with glass containers for extended storage as fluoride can etch glass over time.
How it ships from Indonesia
Standard packing and export terms for this product. Confirm exact figures against your order — they vary slightly by destination and quantity.
What travels with every batch
Specification is agreed before the purchase order, not discovered on arrival. Every shipment of Potassium Fluoride leaves with a documented, checkable paper trail.
Certificate of Analysis
Batch-wise assay (by titration/GC), colour and relevant physical constants, issued against the agreed specification so your QC team can check it, not just file it.
Safety Data Sheet
GHS-format SDS in English covering hazard classification, handling, storage, first-aid and spill response for the exact grade of Potassium Fluoride shipped.
Technical Data Sheet
Reference physical and chemical properties, recommended storage and typical applications, for internal circulation to your process or R&D teams.
Certificate of Origin
Confirms Indonesian origin for customs clearance and any preferential-duty claim at your destination port.
Dangerous Goods Declaration
UN packing group, classification and shipper's declaration prepared ahead of loading so documentation never holds up customs.
Third-Party Inspection
Independent pre-shipment inspection and re-sampling can be arranged on request, at your cost, for buyers who require it as a matter of policy.
