Tin Dioxide (SnO₂): Transparent Conductive Films For Displays, Gas Sensors, Ceramic Glazes, Environmental Catalysts
Also called "tin oxide". Chemical formula: SnO₂. Molecular weight: 150.69. White tetragonal crystals (also exists in hexagonal or orthorhombic forms), turns yellow when heated. Melting point: 1127°C, sublimes at 1800-1900°C, relative density: 6.95, refractive index: 1.997, 2.093.
SnO₂ shows excellent stability to air and heat. Insoluble in water and resistant to most acids/alkalis, but soluble in hot concentrated sulfuric acid, molten caustic alkalis and potassium hydroxide, slightly soluble in alkali metal carbonate solutions. Generally inert to chemical reagents and nitric acid. Slowly converts to chloride when heated with concentrated HCl. Reduced to metallic tin by hydrogen at high temperatures. Reacts with CO to form metallic tin and CO₂ (reversible reaction).
Applications
1.Electronics Industry
● Transparent conductive films: Used in LCDs, touchscreens and solar cells due to high conductivity and transparency.
● Gas sensors: Detects combustible/toxic gases with high sensitivity and fast response.
● Varistors: By doping with metal oxides (e.g. CoO, Nb₂O₅), used in power systems and circuit protection.
2.Glass & Ceramics
● Glass manufacturing: Acts as clarifier and colorant to enhance transparency/hardness (e.g. opal glass, optical glass).
● Ceramic glazes: Improves gloss, wear/chemical resistance (tiles, sanitaryware).
3.Catalysts & Environmental
● Organic synthesis/exhaust treatment: Catalyzes oxidation reactions (nitric/acetic acid production) and purifies automotive exhaust.
● Photocatalysis: Degrades organic pollutants in water/air treatment.
4.Other Industrial Uses
● Coatings/pigments: White pigment that enhances hardness/heat resistance.
● Specialty materials: Used in Ag-SnO₂ electrical contacts (replacing toxic Ag-CdO), electrodes and polishing agents.
