In summary, the conversation is about finding a way to coat the inside of a small nickel plated steel can with a conductive graphite layer to prevent ZnCl2 from reacting with the metal. The person mentions using Aquadag, but it may not provide enough conductivity. They also consider using silver as a coating and ask if it will react with ZnCl2.

Hi ,

I am looking to coat the inside of a small nickel plated steel can (about the same size as an AA battery casing) with a conductive graphite layer that has enough density to prevent ZnCl2 (zinc chloride) reacting with the steel.
The can is filled with some ZnCl2 and I am trying to prevent the ZnCl2 from reacting with the metal whilst keeping the lining of the can highly conductive.
Can this be achieved by paint or other form of coating ?

Don't know if it will work, but we used to use something called "Aquadag" to paint on a nice flat-black graphite coating. http://en.wikipedia.org/wiki/Aquadag

Somehwat surprisingly, you can buy it in little bottles via Amazon: https://www.amazon.com/dp/B008OVGH9A/?tag=pfamazon01-20

Thanks , Aquadag does not provide enough conductivity (too much resistance) , really need to keep the graphite pure.
Alternatively I am thinking about Ag as a coating , does Ag react with ZnCl2 ?

Thanks !
 

FAQ: Can a Conductive Graphite Coating Prevent Zinc Chloride Reaction with Steel?

1. What is the difference between steel and zinc chloride?

Steel is a metal alloy composed primarily of iron and carbon, while zinc chloride is a chemical compound made of zinc and chlorine atoms. Steel is a solid material with high strength and durability, while zinc chloride is a crystalline substance that is typically a white powder.

2. Which one is more corrosion resistant, steel or zinc chloride?

Steel is more corrosion resistant than zinc chloride. This is because steel is able to form a protective layer of iron oxide on its surface, which acts as a barrier against further corrosion. Zinc chloride, on the other hand, is a corrosive substance that can cause damage to metals.

3. How are steel and zinc chloride used in different industries?

Steel is used in a wide range of industries, including construction, transportation, and manufacturing. It is commonly used to make buildings, bridges, cars, and machinery. Zinc chloride, on the other hand, is primarily used in the production of batteries, as well as in the manufacturing of dyes, pharmaceuticals, and other chemicals.

4. Can steel and zinc chloride be used together in certain applications?

Yes, steel and zinc chloride can be used together in certain applications. For example, zinc chloride can be used as a coating on steel to provide additional corrosion resistance. It can also be used as a flux in welding, which helps to remove impurities from the steel and create a stronger bond.

5. Is one more environmentally friendly than the other?

Both steel and zinc chloride have potential environmental impacts. Steel production requires large amounts of energy and can contribute to air and water pollution. Zinc chloride is a hazardous substance that can have negative effects on the environment if not properly managed. However, both materials can also be recycled, which can help reduce their environmental impact.
