What type of amalgam consists of both spherical and lathe cut alloys?

The amalgam that consists of both spherical and lathe cut alloys is classified as admixed amalgam. This type of amalgam combines the properties of both types of alloy particles: spherical particles provide easier handling and decreased voids, while lathe cut particles offer strength and enhance the overall mechanical properties of the mixture. The combination aims to improve the performance characteristics of the amalgam, providing better adaptation, strength, and longevity compared to using either type alone.

While conventional amalgam typically consists of lathe cut particles, high copper amalgam can refer to formulations that use either spherical particles or a high copper content but do not inherently require a mixture of both types. Self-curing refers to a different category not specifically related to the type of particle composition in amalgam. Thus, the distinctive combination of spherical and lathe cut alloys characterizes admixed amalgam as the correct answer in this context.
