Nope, it's a colloidal suspension made of metal particles coated in a surfactant (read an oil) (which also prevents them from joining up) suspended in a liquid phase (normally something hydrophobic to tolerate the oil). It's more of a liquid that has metal inside but cannot split from it.

It's relatively easy to make if you have ammonia handy (which in my country is a regulated substance).
