Glass is not a common ceramic matrix material due to its low strength and poor high-temperature stability compared to other ceramics.

Ceramic composites exhibit increased toughness compared to monolithic ceramics due to the presence of a second phase that can deflect cracks and hinder their propagation.

Carbon nanotubes are widely used as a reinforcement phase in ceramic nanocomposites due to their exceptional mechanical properties, high aspect ratio, and ability to form strong interfacial bonds with the ceramic matrix.

Hot pressing is a common processing technique for ceramic composites, involving the application of high pressure and temperature to consolidate the composite powder mixture.

Ceramic composites often exhibit excellent oxidation resistance due to the formation of a protective oxide layer on the surface, which prevents further oxidation and degradation.

Poor interfacial bonding between the reinforcement and matrix phases is a major challenge in ceramic nanocomposites, as it can lead to reduced mechanical properties and premature failure.

Ceramic composites are widely used in aerospace applications due to their ability to withstand extreme temperatures and harsh environments, such as those encountered during re-entry into Earth's atmosphere.

Nanocomposites exhibit improved mechanical properties, such as increased strength, toughness, and hardness, due to the presence of nanoscale reinforcement phases that can effectively reinforce the ceramic matrix.

Polymer-derived ceramics is a versatile processing technique for fabricating ceramic nanocomposites, involving the conversion of a polymeric precursor into a ceramic material through a series of chemical reactions.

Crack bridging is the primary mechanism responsible for the enhanced toughness of ceramic composites. The reinforcement phase bridges the crack, transferring load and preventing its propagation.

Ceramic nanocomposites with a low dielectric constant are desirable for applications in electronic devices, as they reduce signal propagation delay and improve device performance.

Poor biocompatibility is a major challenge associated with the use of ceramic composites in biomedical applications, as they can elicit adverse reactions in the body.

Nuclear waste disposal is not a typical application area for ceramic nanocomposites, as they are primarily used in high-performance engineering and electronic applications.

Ceramic composites are widely used in high-speed cutting tools due to their excellent wear resistance, which enables them to maintain sharp edges and prolong tool life.
