    摘要: Substantially homogeneous, substantially spherical interdiffused metallic oxide particles, especially useful in plasma spraying applications, are readily and economically prepared from constituent metal oxide powders by the method of this invention which includes the step of heating a mass of discrete agglomerated particles under conditions of temperature and time sufficient to interdiffuse the constituent metallic oxides within the agglomerates, but insufficient to sinter the agglomerates together.

    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.

    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.
