Ceramics are generally known for their chemical stability and resistance to chemical reactions and corrosion.
They are inert and do not react with acids or bases.
However, there are some exceptions to this rule.
For example, exposed ceramic heating elements made of silicon carbide can react with atmospheric gases at elevated temperatures.
This reaction can lead to an increase in electrical resistance over time, affecting the performance of the heating element.
5 Key Points to Consider
1. Chemical Stability
Ceramics are typically chemically stable and do not react with most substances.
2. Exceptions to the Rule
Certain conditions, such as high temperatures, can cause ceramics to react with atmospheric gases.
3. Integration with Other Materials
Integrating ceramics with other materials like metals, glass, and polymers can be challenging due to differences in melting points.
4. Metal Ceramic Sintering
Metal powder can be added to clay to make ceramics more resistant to high temperatures and less prone to breaking.
5. Metalloceramics
Metalloceramics are prepared by adding oxide powder to a metal matrix, enhancing their properties.
