SnO₂ – SnF₂ granules are a composite granular material consisting of tin dioxide (SnO₂) and tin fluoride (SnF₂).
Composition analysis: Composed of SnO₂ and SnF₂.
Colour change pattern: it shows different shades from white to off-white.
Crystal structure: SnO₂ has rutile tetragonal crystal structure, SnF₂ has layered crystal structure.
Density properties: The density of SnO₂ is about 6.95 g/cm³ and the density of SnF₂ is about 4.57 g/cm³, so that the density of SnO₂ – SnF₂ particles depends on the ratio of SnO₂ to SnF₂ and lies between these two density values.
Lithium-ion batteries: Fluorine doped Tin Oxide particles are used as anode materials in lithium-ion batteries, where the tin elements in SnO₂ and SnF₂ can react reversibly with lithium ions.
Gas sensors: Gas sensors are prepared based on the semiconducting and chemisorption properties of SnO₂ – SnF₂ particles. When the sensor is exposed to the target gas environment, the gas molecules are adsorbed on the surface of the particles, resulting in changes in the electrical properties of the particles (e.g. resistance, capacitance, etc.).
Catalysis: Fluorine doped Tin Oxide particles have a catalytic role in a number of chemical reactions. the crystal structure and surface properties of SnO₂ enable it to adsorb reactant molecules, facilitating the reaction.
VI HALBLEITERMATERIAL GmbH (VIMATERIAL) employs a stringent quality assurance system to ensure the reliability of our product quality. Strict quality control is implemented throughout the entire production chain, and for defective products, we strictly enforce the principle of rework and redo. Each batch is released only after passing detailed specification tests.
Every batch of our materials is independently tested, and, if necessary, we send samples to certified companies for testing. We provide these documents and analysis certificates with the shipment to certify that our products meet the required standards.
