What is Tin Oxide?

The chemical formula of stannous oxide is 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.

Application of Tin Oxide

SnO has decreasing residential properties as well as can be utilized as a lowering agent to prepare stannous salt. The response of stannous salt solution with sodium hydroxide solution generates stannous hydroxide Sn( OH) 2, which is after that heated and broken down to produce stannous oxide. As a result it is extensively used in fields such as stimulant, electroplating and glass industry. Tin oxide is generally utilized in cosmetics as a sunscreen, frequently in combination with mica and titanium dioxide. Its application examples are as adheres to:

1. Tin oxide is an important metal oxide that can be utilized as the unfavorable electrode material of lithium batteries. Compared to batteries with carbon products as the unfavorable electrode, its efficiency has greater volume certain energy and also mass details power, and also its academic reversible discharge ability Approximately 880mAh/g.

2. Used to prepare a stannous oxide textured film. Tin oxide is a basic binary oxide. As a result of the anisotropy of the split framework of tin oxide, its transport homes are also anisotropic. According to theoretical estimations, the effective hole mass of SnO is anisotropic, which makes it simpler for holes to jump as well as perform within layers than in between layers.

For that reason, it is extremely important to adjust the crystallographic positioning of SnO by experimental approaches. At present, Tin Oxide has actually been commonly examined in slim movie transistors, gas sensing units, etc, particularly p-type and also bipolar slim film transistors with excellent efficiency have been prepared with tin oxide as the network layer. The stannous oxide textured movie makes up from base to top: a substrate, a stannous oxide major layer and also a steel oxide covering layer, and also the preferred orientation of stannous oxide in the stannous oxide primary layer is (101 ).

The metal oxide finish alters the Sn/O of stannous oxide, the surface area energy of stannous oxide, and also the user interface power in between stannous oxide and also the substratum, consequently regulating the crystallographic positioning of the movie. The steel oxide finishing ought to be steady in performance, Does not react with the primary layer of tin oxide, can reduce the diffusion of oxygen, such as: Al2O3, ZnO, Y2O3, HfO2, and so on.

Production Method 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, and process parameter is easy to control, and cost is low, and the stannous oxide purity that makes is high, can reach more than 99%, crso.02%, product dissolves in formazan The solution was clear after sulfanic acid.

The main technical scheme adopted to realize the object of the present invention is: 1. neutralization reaction: the Tin Oxide of crystallization and sodium carbonate are dissolved into solution, while stirring, sodium carbonate solution is gradually added in the tin protochloride 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, until the concentration of cr is less than 0.2%, adding an antioxidant, and after the product is filtered, it is heated and vacuum-dried to obtain stannous oxide.

Concrete technical scheme of the present invention also includes:

During neutralization reaction, the weight percent concentration of Tin Oxide solution is 30%~50%, sodium carbonate solution concentration 18~22%; During conversion reaction, sodium hydroxide solution concentration is 4%~15%, the pH of control reaction solution Value is 10~12, keeps reaction solution boiling 1h.

In the washing and drying process of the present invention, the antioxidant added after washing is cresol sulfonic acid, and the amount added is 2ml antioxidant for every 500g crystallized Tin Oxide, and the drying is at 80°C. C~100. Under C, the time is 2h~3h.

Compared with traditional production methods, the present invention has the following advantages:

1. Adopting one-step neutralization conversion, the production process is simplified, and the direct recovery rate is improved. The direct recovery rate of the traditional production method is about 96%, and the direct recovery rate of the present invention can reach more than 98%. 2, use sodium hydroxide instead to convert, strengthen the pH value during conversion, make the product conversion complete, improve the main content of the product, the main content of the traditional production method is about 98%, and the main content of the product produced by the present invention is greater than 99% %.

3, after the present invention has added antioxidant, the stability of product improves, and after being dissolved in 30% methanesulfonic acid solution, solution is clear.

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 stannous oxide;

4) The finished product of Tin Oxide can be obtained after the crude Tin Oxide is dried, washed, dried and sieved.
