The viscous behavior of agZIF-62 was investigated through ball penetration viscometry, following the work of Douglas et al. using a vertical thermomechanical analyzer (Netzsch TMA 402 F1 Hyperion) equipped with an alumina punch and well-defined sapphire spheres as penetration objects. Prior to actual measurements, the temperature at the position of the sample was calibrated through reference measurements of a set of pure metals (≥99.99%) with well-known melting points in the relevant temperature range (In, Sn, Bi, Zn, Al).
