Do Ceramics Have Corrosion Resistance? 5 Key Points to Know

Ceramics have excellent corrosion resistance.

They are highly resistant to corrosion from water, neutral and acidic liquids, concentrated acids and acid mixtures, chlorine, bromine, iodine, and organic compounds.

Ceramics also have superior chemical attack resistance compared to other metals and materials.

They can withstand extended exposure times and temperatures above 100°C without visible corrosion.

Borosilicate glass, a type of ceramic, can even withstand caustic solutions of up to 30% concentration at ambient temperatures without difficulties.

5 Key Points to Know About Ceramic Corrosion Resistance

Do Ceramics Have Corrosion Resistance? 5 Key Points to Know

1. Wide Range of Chemicals Resistance

Ceramics are resistant to a broad spectrum of chemicals, including water, neutral and acidic liquids, concentrated acids, chlorine, bromine, iodine, and organic compounds.

2. Superior Chemical Attack Resistance

Compared to other metals and materials, ceramics offer superior resistance to chemical attacks.

3. Extended Exposure and High-Temperature Resistance

Ceramics can endure prolonged exposure times and temperatures above 100°C without showing signs of corrosion.

4. Borosilicate Glass's Caustic Solution Resistance

Borosilicate glass, a specific type of ceramic, can handle caustic solutions up to 30% concentration at room temperature without issues.

5. Wear Resistance and Extreme Condition Tolerance

In addition to corrosion resistance, ceramics are highly resistant to wear. They can withstand high temperatures, pressures, and other extreme conditions.

Some ceramics, like those with physical vapor deposition coatings such as titanium nitride, are not only wear-resistant but also highly resistant to tarnishing and corrosion.

These coatings are used for decorative finishes on items like watches, door handles, plumbing fixtures, and marine fixtures, providing superior hardness, durability, and resistance to wear.
