Description

Lithium Hexafluorosilicate is an inorganic salt of lithium and hexafluorosilicic acid, known for its role as a versatile source of fluoride and lithium ions. This compound is valued in industrial processes for its ability to introduce these key elements efficiently and with high purity. It is primarily utilized in sectors such as ceramics manufacturing, metal surface treatment, and as a precursor in the synthesis of other lithium and silicon-based materials.

Application

• Ceramics and Glass Industry: Acts as a fluxing agent and opacifier to lower melting temperatures and modify the physical properties of glazes and glass compositions.
• Metal Surface Treatment: Used in aluminum anodizing and other metal finishing processes to form protective coatings and enhance corrosion resistance.
• Lithium-Ion Battery Research: Serves as a potential precursor or additive in the development of advanced electrolytes and cathode materials for energy storage systems.
• Chemical Synthesis: Employed as a fluorinating agent or a source of silicon tetrafluoride (SiF4) in organic and inorganic synthesis.
• Wood Preservation: Functions as an active ingredient in formulations designed to protect timber from fungal decay and insect infestation.
• Water Fluoridation (Industrial Grade): Used in specific industrial water treatment applications where controlled fluoride release is required.

Quality Control

Our Lithium Hexafluorosilicate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can lead to caking or decomposition. Keep away from strong alkalis.
