Physicochemical properties and preparation method of antimony oxide

Antimony oxide is a chemical component, there are two kinds of antimony trioxide Sb2O3 and antimony pentoxide Sb2O5. Antimony trioxide is white cubic crystal, soluble in hydrochloric acid and tartaric acid, insoluble in water and acetic acid. Antimony pentoxide is light yellow powder, insoluble in water, slightly soluble in alkali, and can generate antimonate.

Physical and chemical properties of antimony oxide

Antimony trioxide is white cubic crystal; melting point is 656°C, relative density is 5.2; amphoteric, stronger than acid; easily soluble in acid; solubility in water is 0.002g/100ml water. Antimony trioxide turns yellow when heated to 300-400°C in the air, and antimony (III) [SbIII(SbVO4)] can be obtained, and its relative density is 5.82, and oxygen is released when heated to become antimony trioxide. . Antimony trioxide and strong alkali are melted to obtain M2SbⅢ(SbⅢO4) type salt (M is a monovalent metal). The Sb2O3 vapor molecule is a dimer Sb4O6, which begins to dissociate into Sb2O3 above 800°C, and dissociates almost completely at 1800°C.

Antimony pentoxide is light yellow powder; insoluble in water, slightly soluble in alkali to form antimonate.

Antimony oxide preparation

Antimony oxide is obtained by melting or burning antimony metal in air.

Overview of Antimony Oxide ATO Powder

Antimony tin oxide is also called antimony doped tin dioxide, or ATO for short. It is a non-resistance transparent conductive material in the semiconductor field. It can be used in all kinds of glass, plastic, and various resins, and plays the role of transparent, conductive, anti-static radiation, ultraviolet and infrared blocking. Antimony tin oxide conductive nanomaterials have broad application prospects in many fields due to their high conductivity and light-color transparency. This is a new type of functional material that has developed rapidly in recent years.

Antimony oxide ATO powder is recognized as an excellent material in the world, with a series of unique properties. They exhibit good conductivity in antistatic applications and have good infrared absorption. It has a strong absorption effect on near-infrared light, and can maintain transparency in the visible light range in the film.

ATO (antimony tin oxide) is a highly insoluble, thermally stable source of aluminum for glass, optical and ceramic applications. Antimony tin oxide is one of the most commonly used transparent conductive oxides because it possesses two key properties, including optical transparency and electrical conductivity. These properties are important for photovoltaic devices including solar cells and flat panel displays.

Current techniques to form particulate and nanoparticulate tin oxide and use acidic media to provide surface coatings, however, coating acid-sensitive materials with nanoparticle-doped antimony oxide (ATO) thin films has become very important.

Antistatic coating is the main application market of nano ATO powder. Nano-composite transparent antistatic coating can be prepared by adding nano-ATO powder as conductive filler to matrix resin (such as polyamide, acrylic), and selecting appropriate dispersion method. Since the past conductive fillers generally use carbon black, they are not as good as ATO powder in terms of color control.

Application of antimony oxide ATO powder

When the fiber is spinning, the nano-scale ATO powder is directly added. The key is the compatibility of the inorganic nano-scale ATO with the fiber material, and special dispersing additives need to be added;

Add nano-scale ATO or textile auxiliaries during the dyeing process of raw materials (such as tops, polyester yarn) to complete dyeing and functionalization in one step;

Add nano-level ATO textile auxiliaries in the process of grey fabric dyeing or finishing.

Nano ATO powder has small particle size, good compatibility with plastics and light color, which expands the application range of conductive powders in plastics. Conductive ATO can be made into plastic additives, or plastic conductive masterbatch can be made into conductive plastic. If the ATO particles are larger, it will have a certain negative impact on the production of conductive plastics. Therefore, ATO raw materials with the smallest possible particle size are required. Other applications for antimony tin oxide include:

1. Antimony tin oxide nanoparticles exhibit excellent electrical and optical properties.

2. Antimony oxide can be used in optoelectronic display devices and flat panel display devices, such as LED, LCD, ECD, etc.

3. Antimony oxide can also be used in solar cells and transparent electrodes.

4. The high conductivity of antimony oxide makes it suitable for use as an antistatic material in coatings, chemical fibers, polymer films and other industries.

5. Antimony tin oxide nanoparticles also exhibit high heat resistance.

6. Antimony oxide can be used for thermal insulation in buildings or in glass and hot mirrors.

7. Antimony oxide can also be used in automobile glass and aircraft glass to prevent fogging and frosting.

8. Antimony tin oxide nanoparticles have the property of reducing microwaves.

9. Antimony oxide can be used in areas that need to shield electromagnetic waves. These areas include the computer room and radar.
