Which of the following properties of silicon is not exploited in the manufacture of non-stick cookware?

Options

A. high resistance to heat
B. poor electrical conductivity
C. non-stick nature
D. high resistance to chemicals

Explanation

To answer the question about which property of silicon is not exploited in the manufacture of non-stick cookware, we need to consider the properties of silicon and how they relate to non-stick cookware.

### Step-by-Step Solution:

1. **Identify Properties of Silicon**:
- Silicon is known for its high melting point, thermal stability, and ability to form strong bonds with oxygen. It is also a semiconductor and has a low reactivity with many substances.

2. **Understand Non-Stick Cookware**:
- Non-stick cookware is typically coated with materials that prevent food from sticking. Common materials include Teflon (PTFE) and silicone-based coatings.

3. **Determine Relevant Properties for Non-Stick Cookware**:
- The properties that are beneficial for non-stick cookware include:
- **Low surface energy**: This helps in preventing food from sticking.
- **Thermal stability**: This ensures that the cookware can withstand high cooking temperatures without degrading.
- **Chemical inertness**: This prevents reactions with food.

4. **Identify Irrelevant Properties**:
- Properties such as **semiconductor behavior** or **high electrical conductivity** are not relevant to non-stick cookware. These properties do not contribute to the non-stick feature or the cooking performance of the cookware.

5. **Conclusion**:
- The property of silicon that is not exploited in the manufacture of non-stick cookware is its **semiconductor behavior**.

### Final Answer:
The property of silicon that is not exploited in the manufacture of non-stick cookware is its **semiconductor behavior**.
