    It's not trouble. You take a finely dispersed mixture of the
    micronized metal and graphite, hydralically compact near net,
    then ignite a solid flame with a hot wire.

    Google
    carbides "solid flame" 28 hits
    carbide "solid flame" 32 hits

    Even titanium carbide is fun - and much more electrically
    conductive than the pure metal.
