In the evolving landscape of fluorine chemistry, efficient resource recovery and sustainable production have become top priorities. The fluorosilicic acid to hydrofluoric acid device represents a critical innovation that transforms a common industrial by-product—fluorosilicic acid (H₂SiF₆)—into high-value hydrofluoric acid (HF). This advanced system, developed by Jiangsu Kesheng Intelligent Manufacturing Co., Ltd., leverages precise thermal control and intelligent automation to offer a cleaner, safer, and more economical method for HF production.
Why Convert Fluorosilicic Acid?
Fluorosilicic acid is a by-product typically generated during phosphate fertilizer production. While traditionally considered waste, it contains a high concentration of fluorine and can serve as a raw material for hydrofluoric acid—an essential chemical in industries ranging from electronics and glass etching to lithium battery materials and high-performance coatings.
By converting H₂SiF₆ into HF, this device provides a value-added recycling solution that reduces environmental discharge and creates economic benefits.
How the Device Works
The core principle of the device is the thermal decomposition of fluorosilicic acid:
Under controlled high temperatures—often using microwave heating technology—H₂SiF₆ breaks down into hydrogen fluoride and silicon tetrafluoride (SiF₄). The HF is then separated, purified, and collected for industrial use.
The system is designed with corrosion-resistant materials and high-efficiency heating zones to ensure stable operation in harsh chemical environments. Advanced process monitoring ensures safety and product purity throughout the reaction.
