Show II eltin metal A note concerning the peculiar phenomenon noticed in the melting of metals when under extended pressure liaa recently been published by 11 bischof of wiesbaden Wies baden when a metal is bedded in a mortar of chemically pure aluminium 0 bide thoroughly dried and then subjected to the necessary heat beat a considerable sid erable ablo retardation in melting is noticed for instance a rod of silver which should melt at 1830 degrees F when thus treated will not change it its S form and melt together until do 10 arces re es F palladium which should in melt e it pt t 2780 2730 degrees za P F shows no sign of yielding at 2900 2000 degrees F it would seem that these rods of metal unable to expand while in the powerful grip ot of the aluminium oxide which contracts on heating beating simply cannot melt as they would under normal conditions |
