摘要： Ferrite particles having a plurality of distinct Curie temperatures are encapsulated within a glass matrix to provide tagging material especially useful in identifying explosive materials even after detonation. In one embodiment, phosphor is dispersed within the glass matrix or an intrinsically fluorescent glass is employed to facilitate visual identification and collection of tag particles following detonation. The tags are also usable in tagging other articles, especially where harsh environmental conditions are likely to be encountered.

摘要： Magnetic particles, particularly ferrites, exhibiting a plurality of distinct Curie temperatures are disposed within standard center-fire or rimfire cartridge ammunition to provide a method for identifying cartridges. In one embodiment, magnetic particles are disposed within the projectile portion of the cartridge; in another embodiment, the magnetic particles are disposed within the primer of the cartridge; and in still another embodiment, magnetic tagging particles are disposed on or about the cartridge casing.
