The metal component of an admixed amalgam is produced by which method?

An admixed amalgam combines both spherical and lathe-cut particles of metal, which provides distinct properties such as improved packing and strength. The production of the metal component for admixed amalgam involves two techniques: lathe cutting and melting and spraying.

Lathe cutting involves machining an ingot of alloy to produce lathe-cut particles, which are flat and allow for greater surface contact when mixed with the spherical particles. This technique contributes to the overall strength and handling characteristics of the amalgam.

Simultaneously, the melted and sprayed method produces spherical particles by heating an alloy to a molten state and then spraying it into a chilled environment. This creates small spherical particles that can blend well with the lathe-cut particles, adding to the admixed amalgam's ability to achieve a dense, smooth mix upon condensation.

Therefore, since both methods of producing the metal component are utilized in the creation of admixed amalgam, the correct answer is that both processes contribute to the final product, making the combination of these methods essential for achieving optimal physical and mechanical properties in the amalgam.
