Which characteristic is commonly associated with compactability in tableting?

Tableting compactability refers to how well powders can be compressed into tablets without compromising the structural integrity of the final product. The correct answer highlights the relationship between tensile strength and solid fraction, which is a key indicator of compactability.

When assessing compactability, it is crucial to understand that the tensile strength of a tablet is indicative of how well the particles bond to each other during compression. As the solid fraction increases (meaning more of the powder is occupied in the tablet), the tensile strength typically increases up to a certain point. This relationship indicates that the powders are effectively compacting and forming strong bonds, which leads to tablets that can withstand handling and storage without breaking.

A strong tensile strength in relation to the solid fraction ensures that the tablet maintains its form and integrity, aligning with the principles of effective tableting process design. This aspect is vital for the manufacturability and performance of dosage forms, ensuring that the tablets can withstand mechanical stress during production and transportation.

Considering other options, while they also relate to the physical properties of tablets, they do not directly connect to the primary mechanism of compactability as characterized by tensile strength and solid fraction. For instance, resistance to capping refers to a specific failure mode during production rather than overall compact
