A primer includes a layered thermite coating comprising alternating layers of metal oxide and reducing metal (thermite) deposited upon a substrate. The layered thermite coating may include a primary ignition portion adjacent to the substrate, and a secondary ignition portion deposited on the primary ignition portion. The alternating thermite layers may be thinner within the primary ignition portion than in the secondary ignition portion. The primary ignition portion is structured for sensitivity to a firing pin strike to the opposite side of the substrate. The secondary ignition portion is structured to burn at a rate that will ignite smokeless powder or other ignitable substances used in munitions.

Provided is an oxygen candle starting device, comprising a pull line column (17) and a percussion cap (15), wherein a pull line hole (155) is provided in the pull line column in an axial direction of the pull line column, a percussion cap cavity (154) is provided inside one end of the pull line column, a fire-preventing cavity is provided inside the other end of the pull line column, and the pull line hole passes through the fire-preventing cavity and the percussion cap cavity; the percussion cap is mounted in the percussion cap cavity, and sand grains (16) are packaged in the fire-preventing cavity. Further provided is an oxygen candle comprising the oxygen candle starting device and an oxygen generator, wherein the oxygen generator comprises an agent loading housing, with a through hole being provided in the top of the agent loading housing, a gas outlet being provided in the bottom thereof, and a filter being mounted at the gas outlet; and the percussion cap of the oxygen candle starting device is in contact with an oxygen candle agent via the through hole, the oxygen generator is connected to the agent loading housing in a sealed manner, and the filter is connected to the gas outlet in a sealed manner. The oxygen candle employs a pull-type starting device, and the starting structure for an existing oxygen candle is simplified, thereby preventing a false start caused by the falling-off of a steel needle and improving the reliability.

An ignition system includes a multi-metallic ignition body that has at least two metallic elements in contact with each other. The metallic elements define an ignition initiation temperature above which there is a self-sustaining alloying reaction. A fluorine-containing body is in contact with the multi-metallic ignition body. The metallic elements may include palladium or palladium-ruthenium and aluminum.

The present invention relates to a nano-energetic material (nEM) composite having ignition and explosion characteristics by a low-power laser pointer beam and capable of being remotely and optically ignited by adding black powder to nEM composite powder, and a method of preparing the same. The nEM composite includes: nEM composite powder; and black powder used as a mediator for initial ignition to initiate ignition in response to a laser pointer beam and cause a nEM to be continuously ignited and consecutively explode by ignition heat.
