Thermite can be formulated to produce many different effects. One effects described in the rubble is steel that is partially "vaporized" or "evaporated". Another effect described in the rubble is "melting of girders" and "molten steel running down the channel rails" and "like a little river of molten steel".
I've never seen any evidence that depleted uranium was used for ballast in 767s.
What makes you think "large quantities of explosives" would be needed? According to FEMA a very few truss anchors failed, and that initiated a chain reaction bringing the entire building down. That was conventional engineering wisdom for 3 years! Dr. Van Romero opined that a few charges in key place could have brought the buildings down.
