Zinc oxide powder
Zinc oxide powder
It is an organic substance that has a chemical composition of ZnO. ZnO is an oxide form zinc. The substance is not easily soluble or soluble with water. It can be dissolved in strong acids and alkali. Zinc oxide powder, an important chemical additive is used widely in plastics and silicate products. High transparency and good room-temperature light-emitting ability are some of the advantages that zinc oxide powder offers. You can use it in liquid crystal displays and thin-film transistors. It also makes light-emitting dimdes. Micro-particle zinc dioxide as a nanomaterial is also being used.
Zinc oxide powder’s physical characteristics
Property and appearance: hexagonal or white crystals. Non-sandy and tasteless. The substance turns yellow upon heating, then becomes white again on cooling. This concealment power is twice that of titanium dioxide or zinc sulfide. It has twice the tinting power of basic lead carbonate.
Solubility
Zinc oxide powder chemical properties
Zinc oxide powder It is also known by the common name of zinc white. The advantage of ZnO is its inability to turn black when it comes into contact with H2S gas, as ZnS itself is white. ZnO changes gradually from light yellow to lemony yellow as it heats. As it cools down, the yellow disappears. You can mix it with paint, or add to a thermometer for a color changing paint. ZnO can be used to make medicine ointments because it has an anti-bacterial andstringency. ZnO can be used to create catalysts.
Making zinc oxide powder
1. Direct Method:
1. You can obtain it by calcining Zinc Carbonate. ZnCO3=ZnO+CO2|
2. You can get it by calcining or decomposing zinc hydroxide.
3. Zinc can be made by melting crude zinc oxide. Then, it is oxidized with high-temperature oxygen.
4. Obtained by the oxidation and fusion of molten Zinc.
5. These methods include: The indirect method, also known as the French Method using zinc ingots for raw material; the direct method using Zinc Ore (also known to be the American Method) and the dry method.
2. Method of indirect.
Reaction equation: 2Zn+O2=2ZnO
Instructions for operation: First heat the ingot of zinc made through electrolysis at 600700 degrees to melt. Next, transfer it to a high-temperature resistive crucible to make it melt. After it has vaporized, cool it down and add hot air to oxidize. Once the oxide has cooled, it is Cyclone separated. Fine particles are then collected in a cloth bag and finally the finished zinc oxide product is produced.
Direct method Reaction equation:
C+O2=CO2
CO2+C=2CO
ZnO+CO=Zn (steam)+CO2
Zn (steam)+CO+O2=ZnO+CO2
Instructions: A mixture of roasted zircon ore (or zinc-containing materials), anthracite, and limestone is used to make balls in a 1:0.5:0.05 ratio. Following reduction at 1300degC and subsequent smelting, zinc oxide in the ore particles is reduced to zinc vapour. The resulting zinc dioxide is captured and used as a raw material for zinc oxide.
3. Methode wet
The zinc ash reacts with sulfuric acids to create zinc sulfate. Next, ammonia and sodium carbonate are combined to make zinc oxide. Here is how the reaction works:
Zn+H2SO4=ZnSO4+H2|
ZnSO4+Na2CO3=ZnCO3|+Na2SO4
ZnSO4+2NH3*H2O=Zn(OH)2|+(NH4)2SO4
This product was made using zinc carbonate as the raw material. zinc oxide can be obtained by washing, drying and pulverizing. ZnCO3-ZnO+CO2|
The zinc oxide product is made from zinc hydroxide, which can be used as a raw material. This includes washing, precipitation and drying. Zn(OH)2-ZnO+H2O
