High-Purity Crystalline Potassium Fluoride 99.42% Assay for Battery Electrolyte
Crystalline potassium fluoride with reference batch data of 99.42% assay and 0.07% moisture, produced on a fluorspar-based fluorine chemical chain.
Product Summary
This crystalline form of potassium fluoride (CAS 7789-23-3) targets buyers who need a high-purity electronic-grade salt for pharmaceutical, pesticide, electronics and battery applications. Reference batch data for the crystal type shows an assay of 99.42% and a moisture content of 0.07%, alongside chloride below 0.01%, sulfate below 0.005%, fluorosilicate below 0.005%, heavy metals as Pb below 0.001% and Fe below 0.0005%. The guaranteed specification remains at least 99.0% potassium fluoride by weight with water no more than 0.3%, so incoming inspection has a clear acceptance window. Two product forms are available, and this page covers the crystalline option; the spray-dried alternative exists for processes where dissolution speed, flowability or storage stability set the requirement.
Key Features
- Reference batch assay 99.42% and moisture 0.07% — actual crystal-type data gives buyers a concrete picture of delivered quality rather than a limit value alone.
- Chloride below 0.01%, sulfate below 0.005%, fluorosilicate below 0.005% — controlled anion impurities support stable behaviour in electrolyte and catalysis duties.
- Heavy metals as Pb below 0.001% and Fe below 0.0005% — metal impurity control addresses contamination concerns in pharmaceutical, pesticide and electronic applications.
- Batch-to-batch consistency for four application families — pharmaceutical, pesticide, electronics and battery users can qualify one source across multiple lines.
- 1,000 tons per year high-purity electronic-grade capacity — supports recurring electrolyte and synthesis programmes instead of one-off lots.
- Fluorspar-rooted supply chain — upstream cooperation in Myanmar, Inner Mongolia and Liaoning keeps raw material supply stable and quality control traceable.

Models and Options
The crystalline form described on this page is one of two product forms. The alternative spray-dried form is supplied where dissolution speed, flowability or storage stability are the deciding factors. Reference data quoted here (99.42% assay, 0.07% moisture) belongs to the crystalline crystal type; the specification table is the guaranteed acceptance basis for both forms.
Materials and Structure
The material is potassium fluoride, CAS 7789-23-3, supplied as white crystals. It is produced within an integrated fluorine chemical chain that runs from fluorspar resources through fluorination processes and high-purity fluoride finishing, with a boron-fluorine dual-element framework that allows mutual material supply and by-product utilisation. The company has supplied high-purity fluoride salts since 2015 and develops products jointly with a domestic fluorine chemical research institute.
Applications
- Electrolyte additive for lithium-ion batteries
- Fluorinating agent and catalyst for pharmaceutical and pesticide synthesis
- Electronic applications requiring tightly controlled metal impurities
- Welding flux and glass etching additive
- Electroplating pretreatment agent
Customization
Buyers can choose between the crystalline and spray-dried forms according to their process, and the sales and technical service team supports specification review, application questions and after-sales follow-up. The stated aim of reducing reliance on imported high-purity potassium fluoride, shortening lead times and lowering procurement cost is delivered through domestic production and a traceable fluorspar-based chain.
FAQ
What assay and moisture can we expect in the crystalline form?
Reference crystal-type batch data shows an assay of 99.42% and moisture of 0.07%. The guaranteed limits are a minimum of 99.0% potassium fluoride and a maximum of 0.3% water.
Which impurity limits matter for battery electrolyte use?
Chloride is capped at 0.01%, sulfate at 0.01%, fluorosilicate at 0.005% and heavy metals as Pb at 0.001%; reference data also shows Fe below 0.0005%.
Is the crystalline form different from the spray-dried form?
Yes. They are two separate product forms offered to meet different process requirements such as dissolution speed, flowability and storage stability. The crystalline form is the one covered by the reference data on this page.
How is quality kept consistent between lots?
Strict impurity control is applied across chloride, sulfate, fluorosilicate, heavy metals and Fe, and the fluorspar-based integrated chain allows traceable quality control from raw material to finished high-purity fluoride.
What capacity is available for electronic-grade potassium fluoride?
The company maintains a stable supply of 1,000 tons per year of high-purity electronic-grade potassium fluoride.
Do you support new application development?
Yes. Continuous product improvement and new application development are carried out in cooperation with a domestic fluorine chemical research institute.
Which sectors does this grade already serve?
The grade is positioned for pharmaceutical, pesticide, electronics and battery applications, including use as a fluorinating agent or catalyst and as an electrolyte additive in lithium-ion batteries.
