Fluorine doped Tin Oxide (FTO)

SnO₂ – SnF₂ target is a kind of composite target of great importance in the field of material science.

Basic Information

Appearance and colour: Different shades from white to off-white.
Common shapes and size specifications: Common shapes include round, square, etc. to suit different sputtering equipment.
Density: The density of SnO₂ is approximately 6.95 g/cm³ and the density of SnF₂ is approximately 4.57 g/cm³, so the density of SnO₂ – SnF₂ powders varies between these two values depending on the mixing ratio of the two.
Hardness: SnO₂ is hard and SnF₂ is relatively soft, so the hardness of the powder mixture also depends on the ratio of the two.

Areas of application

Lithium-ion batteries: Fluorine doped Tin Oxide powders are used as anode materials in lithium-ion batteries, where the tin elements in SnO₂ and SnF₂ can react with lithium ions in a reversible chemical reaction.

Gas sensors: Based on the semiconducting and chemisorption properties of SnO₂ – SnF₂ powders, they can be used to prepare gas sensors.

Catalysis: Fluorine doped Tin Oxide powders have a catalytic effect in some chemical reactions. the crystal structure and surface properties of SnO₂ enable it to adsorb reactant molecules and promote the reaction.
