Grant thermite 893 was a suspension based compound used in remote spectroscopy vaporization devices. The fuel was provided in .005 g pellets for field spectroscopy tricorder use and 0.2 kg charges for use in long-range impact space probes. Per SFRA 83329.6, personnel handling this compound had to protect it from ionizing radiation. In 2367, this compound was stored on aboard the Federation starship USS Enterprise-D.
In that year, Grant thermite 893 was on a list of explosives that Lieutenant Commander Data and Counselor Deanna Troi searched through in an attempt to find one that could produce enough energy to release the USS Enterprise-D and an alien ship from the Tyken's Rift. (TNG: "Night Terrors")
