Question

Thin sheets of ceramic material is produced by:

• A. Tape casting
• B. Rolling
• C. Forging
• D. Injection molding

Hint:

\textbf{Tape casting} is a key technique for fabricating thin ceramic sheets used in capacitors and electronics.

Answer 1

The Correct Option is A

Step 1: What is Tape Casting?
Tape casting is a widely used technique for producing thin, flexible sheets of ceramic materials. It is primarily used in electronics and ceramic capacitor manufacturing. Step 2: Process Description
- A slurry of ceramic powder, solvents, binders, and plasticizers is prepared. - The slurry is cast onto a flat surface using a doctor blade. - The sheet is dried to remove the solvent, resulting in a thin ceramic "green" tape. Step 3: Applications of Tape Casting
- Used for multilayer ceramic capacitors (MLCCs), - Fuel cell electrolytes, - Substrates in microelectronics. Step 4: Elimination of Incorrect Options
- Rolling and Forging: Suitable for metals, not ceramics.
- Injection Molding: Used for complex 3D ceramic shapes, not thin sheets. Conclusion: Thin ceramic sheets are produced using the tape casting process.
