Answer:
Malleable.
Step-by-step explanation:
Ceramics are typically known for their strength, hardness, and high melting points. They are also good insulators of heat and electricity, and are generally chemically unreactive. However, ceramics are not malleable, meaning they cannot be easily shaped or bent without breaking. This is because ceramics are brittle and prone to fracture under stress. Therefore, the property that is NOT a property of ceramics is malleability.
