Title: SELF-GLOWING MATERIALS, TRACER AMMUNITION, AND ILLUMINATION DEVICES
Abstract:
A self-glowing solid material comprises a man-made metal mixture containing at least one rare earth metal and an oxide of iron. The material is inducible by flame initiation to self-glow with yellow-to-red colors (577-to-700 nanometer wavelengths). A stealth tracer ammunition comprises a projectile body having a tip and a base, and a solid pellet disposed in the base. The pellet may be made from the above-mentioned self-glowing solid material or another suitable material. The pellet becomes incandescent as a result of being heated when the ammunition is fired. The incandescent pellet emits a glow observable only from behind when the ammunition travels downrange after being fired.
