Product Summary

Potassium fluoride (CAS 7789-23-3) from Changzhou Jiayuan Chemical Co., Ltd. is supplied in a spray-dried product form. Two product forms are available from the same production chain, and the spray-dried option is intended for processes where dissolution speed, flowability and storage stability drive the purchasing decision. The guaranteed specification is a potassium fluoride content of at least 99.0% by weight, water content no more than 0.3%, free acid as HF no more than 0.2%, free base as KOH no more than 0.2%, chloride no more than 0.01%, sulfate no more than 0.01%, fluorosilicate no more than 0.005% and heavy metals as Pb no more than 0.001%. Typical uses are as a fluorinating agent or catalyst, a welding flux component, a glass etching additive and an electroplating pretreatment agent.

Key Features

• Assay of 99.0% minimum with water no more than 0.3% — a defined active content supports repeatable fluoride dosing across batches instead of trial-and-error adjustments.
• Chloride no more than 0.01% and sulfate no more than 0.01% — capped impurity levels help protect flux and etching bath chemistry from drifting.
• Fluorosilicate no more than 0.005% and heavy metals as Pb no more than 0.001% — tighter ceilings on problematic impurities support stable downstream performance.
• Spray-dried form alongside a crystalline form — lets a buyer select the form that suits dissolution speed, flowability and storage stability requirements.
• Integrated fluorspar-based supply chain — upstream cooperation on fluorspar operations in Myanmar, Inner Mongolia and Liaoning supports traceable raw material sourcing.
• 1,000 tons per year of high-purity electronic-grade potassium fluoride — installed supply capacity supported by technical service from product selection through use.

Technical Specifications

Models and Options

Two product forms are offered: spray-dried and crystalline. This page covers the spray-dried form with the specification table above. The crystalline form is the alternative where a crystalline crystal type is preferred, and reference batch data for that form shows assay 99.42% and moisture 0.07%. Buyers comparing the two forms should state the process step, the required dissolution behaviour and the storage conditions so the matching form can be recommended.

Materials and Structure

The product is potassium fluoride, an inorganic fluoride salt with the CAS number 7789-23-3, supplied as white crystals. Production sits inside an integrated fluorine chemical chain that starts at fluorspar and continues through fluorination processes to high-purity fluoride salts, with mutual supply of materials and by-product utilisation across the company’s fluoride and boron-fluorine lines. R&D collaboration with a domestic fluorine chemical research institute supports continuous product improvement.

Applications

• Welding flux formulations
• Glass etching additive
• Electroplating pretreatment agent
• Fluorinating agent and catalyst
• Electrolyte additive for lithium-ion batteries

Customization

Selection support is available from first enquiry through to use: the product form (spray-dried or crystalline) is chosen against the buyer’s process requirements, and the sales and technical service team supports specification alignment and application questions. Continuous product improvement and new application development are carried out with a domestic fluorine chemical research institute.
