Compact materials are substances that have a high density and are closely packed together. This means that their particles are tightly arranged, which often results in enhanced strength and durability. Examples of compact materials include metals like steel and titanium, which are commonly used in construction and manufacturing due to their robust properties. These materials are essential in various applications, from building structures to creating tools and machinery. Their compact nature allows them to withstand significant stress and pressure, making them ideal for use in environments where reliability is crucial. Additionally, compact materials can also be found in everyday items, such as ceramics and glass.
