Zinc Oxide powder –
Zinc dioxide is an inorganic substance. Its chemical formula, ZnO. Insoluble with water. Solvable in strong acids or bases.
Zincoxide consists of a hexagonal or white powder. The powder is white, sandless and tasteless. When heated, it turns yellow. It sublimates at 1800. The concealing ability is about half that of zinc and titanium dioxide. The tinting ability is two times that of basic lead carboxylate. The zinc o is insoluble in water, ethanol, and concentrated hydroxide bases.
It is also known as zinc white. Because ZnS also is white, it has the benefit of not turning black when exposed to H2S. ZnO slowly changes from light yellow to yellow-white when heated. The yellow color will then fade away as it cools. It is added to thermometers and paints to produce color-changing paints. ZnO, which has a convergence and certain sterilization capability, is often used as an ointment in medicine. ZnO may also be used to create a catalyst. ZnO has been used as a chemical additive in a wide range of materials and products. These include cosmetics, food supplements and rubber. They are also used to make adhesive tape, lubricants and sealants. Zinc oxide is a synthetic product, even though it can be found naturally in the form of zinc.
For thousands of year, skin care products have included zinc oxide. The skin is safe. It is also used in skin care products. Zinc Oxide Cream, Zinc Oxide Diaper Cream, are all made with zinc oxide.

How are and zinc oxide ZnO powders produced?
Direct method
1. Calcined with zinc carbonate.ZnCO3 is ZnO + CO2.
From the calcination zinc hydroxide decomposition.
Smelting crude zinc oxide and converting it to zinc by high-temperature oxidation.
The oxidation reaction of molten zinc.
5. There are several methods that can be used: the indirect method, which uses zinc ingots (also referred to as the French Method), the direct method (which uses zinc ore) as a raw material (also referred to as the American Method), and the wet process.
Indirect method
Reaction equation: 2Zn+O2=2ZnO
Operation: The zinc ingot obtained through electrolysis is heated at 600-700°C after melting. It is then placed in the high temperature crucible for melting and gasification, which occurs between 1250-1300°C, and imported into hot, humid air for oxidation. The cooled and separated zinc oxide by the cyclone and the fine particles captured with cloth bags is the final zinc oxide.
The direct method
Reaction equation:
ZnO+CO=Zn (vapor) +CO2
Zn (vapor ) + CO+O2 = ZnO+CO2
Operation methods:
The proportions of zinc ore (or zinc-containing materials), anthracite, and limestone are 1:0. A ball is prepared by mixing 5:0.05. After reduction smelting, at 1300 hours, zinc oxide is reduced in the ore to zinc vapour, which is oxidized then by air. The resulting zinc dioxide is captured and used to produce zinc-oxide finished products.
The Wet Method:
Zinc oxide is made by combining zinc ash, sulfuric and sodium carbonate. It is then reacted with ammonia. Zinc oxide is made by using zinc hydroxide or zinc carbonate. The reaction formula is:
Zinc +- H2SO4= ZnSO4+H2 write
ZnSO4 + na2CO3 = na2CO3 + znCO3
ZnSO4 nh3 * H2O + 2 = zinc (OH) 2 left + (NH4) 2 so4
The zinc oxide is prepared by washing, drying calcining, and crushing. Write ZnCO3 + > ZnO+ CO2
Zinc oxide can be prepared from zinc hydroxide using water washing precipitation followed by drying, cooling, calcination and grinding.

Use of Zinc oxide ZnO powder
Zinc is an additive widely used for plastics and silicate products. It is also found in paint coatings. The zinc oxide exciton has a wide energy band gap and excellent light emitting properties at normal temperature. They are used for liquid crystal displays, transistors and light-emitting dimmers. Zinc oxide microparticles are also playing a role as nanomaterials in certain fields.
1. Uses: mainly in rubber and cable industries. Also used as active agents and colorants for white gums.
2. Sulfur gas is a raw material used in the fertiliser industry.
3. Mainly used in white pigments, rubber-vulcanized active agents and organic synthetic catalysts.
4. Natural gas, petroleum and synthetic ammonia chemical raw material Gas
5. As a matrix to analytical reagents and reference reagents. Also used as fluorescent agents or photosensitive materials
