The Effect Of Liquid Gallium On Plastics, Vivek P. Dwivedi
Theses
As part of a joint effort by Cornell University and NJIT to find a replacement for mercury as a pressuring medium for P-V-T devices, we investigated the effect of liquid gallium on four thermoplastics: two semi-crystalline ( high density polyethylene and polypropylene ) and two amorphous ( polystyrene and polymethylmethacrylate ). Test specimens were covered with liquid gallium and held in vacuum oven at temperatures close to their melting points for up to two weeks. Change in weight after treatment with gallium was measured, along with tensile testing and particle analysis using dispersion x-ray spectroscopy. The results are compared with …
