Dear Colleagues,

Does anyone know the answers for the following questions regarding the
properties of gallium liquid metal,

1. Is there any solid surface that the melted gallium does NOT wet?
2. Gallium with liquid state has much larger surface tension than mercury
does, and has almost the same small viscosity as water does, but why it can
not form a good sphere drop?
3. Can the solid state gallium be easily oxidized?
4. Could you please recommend some specialists on liquid metals so that I
can consult.

Any answer will be highly appreciated,
