Naquadah is a super heavy mineral, and has superconductor capabilities. It stores massive amounts of energy and is extremely hard. It gives off a unique energy signature that the Goa'uld, former hosts, Jaffa, Tok'ra and Cassandra can detect. However large doses of drugs can counter this. Also handheld sensors, and those on the Prometheus can detect the signature. The energy stored in Naquadah can be released rather efficiently. Small amounts of Naquadah can be absorbed into the blood streams of some creatures. Allied with the host body's bio-electrical impulses, the energy contained within the naquadah in the bloodstream of host and symbiote renders these Goa'uld devices operable when touched. It was stated to be quartz like. Because of the Naquadah in her blood Samantha Carter is resistant to anesthesia. Radio signals cannot pierce large amounts of Naquadah. Naquadah is capable of repeatedly handling an active wormhole, where as Titanium only lasts several minutes under similar conditions. The hardest known substance in the universe is the Asgard created alloy, consisting of carbon, neutrino, and naquadah. Liquid naquadah is capable of firing powerful pulses of energy repeatedly. A variant of Naquadah called Naquadria stores much more power. However it was believed to be created artificially by Thanos, and is only known to exist on Langara. Carter theorizes that the substance can be used to solve hyperdrive technology, as well as shields.
