Ideal requirement of metal ceramic casting____________?
Correct answer: D. All of the above
- A. Low fusing ceramic and high fusing alloys
- B. Matching of coefficients of thermal expansion of ceramics and alloy
- C. Bonding between ceramic and alloy
- D. All of the above
Explanation
A successful metal-ceramic casting requires a compatible high-fusing alloy, a suitable lower-fusing ceramic, closely compatible thermal expansion, and reliable ceramic-metal bonding. Since all three listed requirements contribute, “all of the above” is correct.
