Chemical formula of zinc oxide
The chemical formula of zinc oxide is ZnO.
Chemical formula of zinc oxide
The chemical formula of zinc oxide is ZnO, where Zn represents the
zinc element, whose valence is +2, and O represents the oxygen
element, whose valence is -2. Therefore, the ratio of the number of
zinc and oxygen atoms is 1:1, forming an inorganic compound called
zinc oxide.
Preparation methods and common applications of zinc oxide
Zinc oxide can be prepared by a variety of methods, including
calcination, hydrothermal, sol-gel and solution methods. Each
method has its own characteristics and scope of application, and
the appropriate preparation method can be selected according to
specific needs. The calcination method is suitable for large-scale
industrial production, while the sol-gel method can obtain zinc
oxide powder with smaller particles and uniform distribution. The
application of zinc oxide in the fields of environmental protection
and new energy is also becoming more and more extensive, such as
photocatalytic degradation of organic matter, solar cells, etc.
With the advancement of science and technology and people's pursuit
of high-quality life, the application scope of zinc oxide will
continue to expand, and its importance will become increasingly
prominent. In the future, through continuous research and
innovation, zinc oxide is expected to create a better living and
working environment for us.

The direct method, also known as the French process, involves the
following steps:
1. Raw Material Selection: High-purity zinc materials such as zinc ore or zinc scrap are
used.
2. Smelting: Zinc is heated and vaporized.
3. Oxidation: Zinc vapor reacts with oxygen in a controlled environment to
produce fine zinc oxide powder.
4. Collection and Processing: The resulting ZnO is collected, filtered, and classified to
ensure quality and uniformity.
The production of Zinc Oxide via the direct method is based on the
principle of oxidation of metallic zinc in the presence of oxygen.
The chemical reaction is:
2Zn + O₂ → 2ZnO
This process ensures the formation of high-purity zinc oxide with
uniform particle size.
