Guide to French Process, a Traditional Manufacturing Methods at Zinc Oxide Factory

A zinc oxide factory uses different manufacturing processes to create the final product, zinc oxide. One of them is the French Process. Here, you will learn more about this process and how it works.

What Is the French Process?

This manufacturing process is also known as direct process. It is one of the oldest methods to manufacture zinc oxide. Even though it is a traditional method, many zinc oxide factories are still using it because of its efficiency.

How Does the French Process Work?

The first step of this process is the melting stage. At this stage, we use a high-temperature furnace to melt and vaporize zinc metal. The temperature of this furnace is around 1200 degrees Celsius.

Compared to other metal processing methods, that temperature is considered medium level. However, that is enough to change zinc metal properties from solid to gas. Afterward, the vaporized zinc metal will turn into zinc oxide particles.

After that, the zinc oxide particles will enter a special chamber. Every element, including pressure and temperature, is in controllable status. And, in this chamber, the particles will turn into the final product.

The zinc oxide particles will react to the oxygen inside the chamber. This reaction will solidify the particles and turn them into the zinc oxide product. Then, with some adjustments to the equipment at the zinc oxide factory, you can decide the quality or grades of the final product.

Other than that adjustment, there is also a cooling step in this process. This step determines the conformity of zinc oxide particles. It uses the grade metrics as the base to adjust this conformity level.

All these processes and steps are necessary to ensure the specification of zinc oxide. It includes the purity level, effectiveness, and consistency of zinc oxide.

The Final Result

The zinc oxide factory with the French Process manufacturing method can produce zinc oxide with high purity and excellent chemical reactivity. This kind of product is in high demand for the pharmaceuticals, cosmetics, and ceramics manufacturing industries.

Conclusion

Its ability to create superior-quality zinc oxide is the reason why the French Process is one of the most popular methods in many zinc oxide factories. Many products from the factories that use this method also have been exported to many countries, like Japan, Australia, China, and many more.

Yet, this is only one of many processes to manufacture zinc oxide. You can find other processes you might need to know at the zinc oxide factory.
