Hello,
Ive been trying to make a small Zn/Al disc. So, I started with some Zn tablets and a little piece of Aluminum cable (3% wt or so), and put them in a graphite crucible (fully covered), then heated it in an oven to 800ºC and waited for an hour.
After that, all I get is a poor sintered of the zinc tablets. And one time Ive got nothing but a soft white appearence (oxide i guess)
The melting point of the Zinc is 420ºC, and the aluminum has it at 660ºC. Im working with just a few grams of material
Should I wait more time? should i heat it more? Is there any evident fact im missing here?
THANKS!
