Description

Lithium Metatungstate is a high-density, water-soluble inorganic salt primarily used as a heavy liquid for mineral separation and density gradient applications. Its exceptional stability and consistent performance make it a critical material for precise laboratory and industrial processes where reliable density control is paramount. This product is essential for geologists, materials scientists, and researchers in sectors including mining, ceramics, and advanced materials development.

Application

• Mineral Separation & Sink-Float Analysis: Used as a high-density medium for separating minerals and geological samples based on specific gravity.
• Density Gradient Centrifugation: Employed in the preparation of stable, non-viscous gradients for the isolation of cells, organelles, and macromolecules in life science research.
• Ceramics & Glass Manufacturing: Acts as a high-density additive or filler to modify the physical properties of specialty ceramics and glass composites.
• Radiation Shielding: Utilized in the formulation of high-density polymers and composites for lightweight radiation shielding applications due to its tungsten content.
• Petroleum & Geological Research: Serves as a calibrant and standard in core analysis and porosity measurement techniques.
• Metallurgy & Materials Testing: Applied in the recovery of fine heavy minerals and in density-based quality control processes for metal powders and alloys.

Quality Control

Our Lithium Metatungstate is manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis to verify key parameters such as density, pH, and chemical purity. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure containers are sealed after each use to prevent absorption of atmospheric moisture.
