)[18] Magnetic remanence, recorded while in the iron oxide particles, suggests the energy of Earth's magnetic field after they have been cooled over and above their Curie temperature; this can be made use of to differentiate magnetic particles of terrestrial and meteoric origin.[19] Fly ash consists largely of silica and calcium oxide. Cenospheres are current in smoke from liquid hydrocarbon fuels. Moment metallic particles made by abrasion might be current in motor smokes. Amorphous silica particles are existing in smokes from burning silicones; smaller proportion of silicon nitride particles is often shaped in fires with insufficient oxygen. The silica particles have about 10 nm measurement, clumped to 70–100 nm aggregates and additional agglomerated to chains.[11] Radioactive particles could possibly be present as a result of traces of uranium, thorium, or other radionuclides within the gasoline; scorching particles may be present in the event of fires for the duration of nuclear incidents (e.g. Chernobyl disaster) or nuclear war.
