What is zinc oxide?
Zinc oxide or zinc oxide with the chemical formula ZnO is a widely used mineral compound that is normally in the form of a white powder. The origin of this chemical substance is the mineral zincite and it was also called tutia in the past. This mineral compound currently has different types and its synthetic type is widely used in the industry. Currently, due to its special physical and chemical properties, this mineral compound is used in the production of many chemicals and different products, especially ceramics, rubber, glass, food supplements, cosmetics, paint, glue, etc. as additives. is used. Zinc oxide has many features and characteristics, and for this reason, it is used in many industries.
As mentioned, zinc oxide is used as an additive in food, especially food supplements, and therefore this chemical is completely safe and not toxic in any way. Of course, exposure to compounds such as zinc oxide and rice, which contain zinc oxide alloy, is dangerous and causes people to get metal vapor fever.
Zinc oxide production methods
Now that you are familiar with zinc oxide, we are going to talk about its production methods and provide the necessary information. As mentioned, the production of zinc oxide is done in different ways, which include the following:
A more chemical process: in the wet chemical process method, the production of zinc oxide is done in such a way that zinc carbonate or zinc hydroxide deposits must be obtained from aqueous solutions of zinc salt, and then these deposits, which are solid, must be heated at 800 Calcination at °C.
Direct method: The production of zinc oxide in the direct method is done by melting zinc-containing rocks, and then all the melted materials are reduced to zinc vapors using a carbon source. In the next steps, by increasing the temperature, zinc vapor will react with oxygen, and by decreasing the temperature, zinc oxide will be produced. The zinc oxide produced in this method is of lower quality and purity.
Indirect method: The production of zinc oxide in the indirect method is that zinc metal must first be melted in graphite crucibles and turned into steam at a temperature above 900 degrees Celsius. After that, the zinc vapor will react with oxygen and by reducing the temperature, zinc oxide or ZnO will be produced, which is very bright and bright. After that, zinc oxide particles will be transferred to a cooling duct and collected and stored in a special chamber. This method is considered as the most common and common method of zinc oxide production in the world and a large volume of zinc oxide produced in the world is produced by this method.
Laboratory synthesis: Laboratory synthesis is another method of zinc oxide production, which is known as one of the most specialized methods available. In this method, by applying changes in the oxygen concentration of the final composition, even the color of zinc oxide can be changed to green and red colors.
Applications of zinc oxide
Due to its special physical and chemical properties, zinc oxide has a wide range of applications, including the following:
Industrial items such as the production of glass, ceramics, plastic, rubber, cement, all kinds of paints, softeners, all kinds of industrial adhesives, all kinds of ferrite magnets, all kinds of wax, all kinds of commercial pigments, batteries, all kinds of lubricants, grease, food, etc.
Preparation of tutia or zinc oxide for the production of ointments, sunscreen, baby powder, anti-dandruff shampoo, etc.
Medicinal items such as burn ointments, types of sunscreens, types of anti-itch creams, types of moisturizers, etc.
Cosmetic items such as soaps, deodorants, sunscreens, mineral cosmetics, etc.
Can be used in the production of electrodes for all types of displays, LED lights and transistors
Physical and chemical properties
The physical and chemical properties of zinc oxide are as follows:
Insoluble in water
very transparent
Having a wide energy gap range
It has a melting point of 1974 degrees Celsius
It has a density of 5606 g/cm3
molecular weight 406 (g/mol)
Introduction of zinc oxide family products
Zinc oxide family products also have many uses due to their special properties. Among the most widely used products of the zinc oxide family in the industry, the following can be mentioned:
Gold zinc oxide
Copper oxide
Silver oxide
Platinum zinc oxide
Iron oxide
