I note a question mark at the end of the post, so I'll ask you one back.

Since chains have to be lubricated internally where the parts move against each other (think door hinge), how do you suppose your solid material rubbed onto the outside would get to where it's needed?

OTOH, teflon powder is available as are waxes with various melting points, so nothing stops you from melting some wax, stirring in some teflon, and making your own bar to experiment with.
