What is Tin Oxide?

Tin Oxide chemical formula SnO, soluble in acid and alkali, slightly soluble in NH4Cl, insoluble in dilute alkali, ammonia and water. It can be reduced to metal by heating in hydrogen. It is oxidized to tin(IV) oxide by heating in air. It reacts with Cl2 to form tin(IV) chloride. Oxidation with nitric acid produces H2SnO3. Preparation method: add ammonia water or alkali solution to the tin protochloride aqueous solution until the phenolphthalein changes color, heat and boil to obtain a precipitate, which is obtained by drying under the isolation of air. SnO has reducing properties and can be used as a reducing agent to prepare stannous salt. The reaction of stannous salt solution with sodium hydroxide solution generates stannous hydroxide Sn(OH)2, which is then heated and decomposed to generate Tin Oxide.

Therefore it is widely used in fields such as catalyst, electroplating and glass industry. In recent years, people have prepared SnO by methods such as vapor deposition, homogeneous precipitation, and laser radiation, and studied its properties. From the test results, it needs to be further improved. For example, the SnO-based lithium storage material prepared by research has an initial reversible discharge capacity of only about 400 mAh/g; the reported lithium storage material has a capacity of only about 100 mAh/g after 20 cycles. The emergence of nanotechnology, especially the emergence of high-performance nanomaterials, provides a good opportunity for the study of high-performance lithium-ion batteries.

Due to the small size effect and surface effect of nanomaterials, it exhibits unique photoelectric properties. Therefore, using it to transform lithium-ion batteries can not only greatly increase the specific energy of lithium batteries, but also reduce the intercalation and removal of lithium batteries. Bit, improve the electrode structure and its cycle performance 8 micron Tin Oxide shape has whisker, particle, film, flower shape, disk shape, mesh shape, block shape, platelet flake shape, plate shape, Bipyramidal and dendritic and so on. Different morphologies of Tin Oxide have different application properties. Therefore, more in-depth research is needed on the controllable synthesis methods for preparing Tin Oxide with different morphologies, as well as its formation mechanism and application. Important theoretical value and practical significance.

Tin Oxide Application

Tin Oxide is reductive and can be used as a reducing agent to prepare stannous salt. The reaction of stannous salt solution with sodium hydroxide solution generates stannous hydroxide Sn(OH)2, which is then heated and decomposed to generate stannous oxide. Therefore it is widely used in fields such as catalyst, electroplating and glass industry. Its application examples are as follows:

1. Tin oxide is an important metal oxide that can be used as the negative electrode material of lithium batteries. Compared with batteries with carbon materials as the negative electrode, its performance has higher volume specific energy and mass specific energy, and its theoretical reversible discharge capacity Up to 880mAh/g.

2. Tin Oxide is used to prepare a Tin Oxide textured film. SnO is a simple binary oxide. Due to the anisotropy of SnO layered structure, its transport properties are also anisotropic. According to theoretical calculations, the effective hole mass of SnO is anisotropic, which makes it easier for holes to jump and conduct within layers than between layers.

Therefore, it is very important to adjust the crystallographic orientation of SnO by experimental methods. At present, SnO has been widely studied in thin film transistors, gas sensors, etc., especially p-type and bipolar TFTs with excellent performance have been prepared with SnO as the channel layer. The stannous oxide textured film comprises from bottom to top: substrate, Tin Oxide main body layer and metal oxide covering layer, and the preferred orientation of stannous oxide in the Tin Oxide main body layer is (101).

The metal oxide coating changes the surface energy of Sn/O and Tin Oxide of stannous oxide, as well as the interface energy between tin oxide and the substrate, thereby controlling the crystallographic orientation of the film. The metal oxide coating should have stable performance and not Reaction with the main layer of stannous oxide can reduce the diffusion of oxygen, such as: Al2O3, ZnO, Y2O3, HfO2, etc.

3.Tin Oxide is used in cosmetics as an abrasive, filler and opacifier at concentrations up to 0.4% in rinse-off products and up to 1.3% in leave-on products.

Preparation of Tin Oxide

A kind of method utilizing tin protosulfonate waste liquid to prepare Tin Oxide, comprises the steps:

1) Take tin-containing waste liquid, vacuum distillation to recover water and methanesulfonic acid and other substances, then add tin metal to react, the reaction temperature is 80-95°C, the reaction time is 30-60min, the amount of tin metal added Calculated by adding 10 to 15 kg of tin metal per cubic meter of tin-containing waste liquid; because divalent tin is easily oxidized to tetravalent tin under high temperature conditions, Sn4+ exists in the tin-containing waste liquid, and the chemical reaction in this step is:

2) Dilute the reacted material with water to a tin content of 40-80g/L, filter, wash, and combine the filtrate and lotion; the purpose of diluting with water in this step is to dissolve tin-containing water-soluble substances;

3) adding lye to the combined filtrate and washing liquid for reaction, the reaction temperature is 60-95°C, and the pH value at the end of the reaction is controlled at 5-6, so that impurities such as iron and lead are separated from stannous oxide to obtain Crude Tin Oxide;

4) After the crude product of Tin Oxide is dried, washed, dried and sieved, the finished product of tin oxide can be obtained.

Invention of Tin Oxide

The object of the present invention is to provide a kind of method for preparing Tin Oxide, and its operation is simple, process parameter is easy to control, and cost is low, and the Tin Oxide purity that makes is high, can reach more than 99%, crso.02%, product dissolves in methyl The solution was clear after sulfonic acid.

The main technical scheme adopted to realize the object of the present invention is: 1. neutralization reaction: the tin protochloride of crystallization and sodium carbonate are dissolved into solution, while stirring, the sodium carbonate solution is gradually added in the Tin Oxide solution on the one hand, and the reaction terminal pH Value is 6~7, and reaction solution has white precipitate to separate out;

② Transformation reaction: immediately heat the neutralized reactant, add sodium hydroxide aqueous solution to the material at the same time, keep it in a boiling state, and the conversion is completed when the white precipitate is transformed into a blue-black precipitate;

③ Washing and drying: After the conversion, the reactant is washed with water to remove cr, and the cr concentration is less than 0.2%, after which an antioxidant is added. After the product is filtered, the temperature is raised for vacuum drying to obtain Tin Oxide.

Concrete technical scheme of the present invention also includes:
