The invention relates to a pyrotechnic agent containing at least one azotetrazolate as a component thereof.

Pyrotechnic agent

The invention relates to a primer composition, to a method for producing the same and to the use of said primer composition.

Primer composition

A propellant charge, a priming cap including the propellant charge and a weapons training system including the priming cap are characterized in that the propellant charge contains a soft friction agent. The propellant charge can contain at least one impact-sensitive explosive substance as a heavy-metal-free priming compound, and the soft friction agent can be marble, calcite, dolomite, soft carbonates and/or mixtures thereof.

Propellant charge

The invention relates to a lead- and barium-free ignition charge which does not contain any oxidant, and its use.

Ignition charge

Ignition means for propellant powders include at least one oxidation means, at least one reduction means and at least one binder, and are free from primary explosives.

Ignition means for propellant powders

The invention relates to a heat-generating mixture, to a method and a device for generating heat, especially for heating food such as water, coffee, etc.

Heat-generating mixture and device and method for heat generation

The invention relates to thermal pre-ignition agents and to their use as thermal fuses, in particular for use in gas generators of motor-vehicle safety systems.

Thermal pre-ignition agents

The invention relates to the salts of styphnic acid, to methods for producing the same and to their use.

Salts of styphnic acid

The subject of the present invention is lead- and barium-free propellant charges with primary explosives mixed with oxygen-supplying substances, characterized in that the primary explosives are selected from alkali metal and/or alkaline earth metal salts of dinitrobenzofuroxanes and the oxygen-supplying substances are chosen from metal peroxides, nitrates of ammonium, guanidine, aminoguanidine, triaminoguanidine, dicyanodiamidine, and the elements sodium, potassium, magnesium, calcium, cerium, and/or multivalent metal oxides. The propellant charges according to the invention exhibit increased stability with respect to known propellant charges that are free of harmful substances.

Lead-and barium-free propellant charges

A gas-producing material for a gas generator, particularly, for an inflatable impact cushion for protecting motor vehicle passengers is made up of a combustible liquid gas mixture of one or several short-chain hydrocarbons and nitrogen monoxide. As a result of exothermic action during combustion there is a multifold increase in volume so that no filters which are required for solid matter generators, are necessary.

Gas-producing material

A gas-producing material for a gas generator, particularly for a belt tightener or for an inflatable impact cushion (airbag) to protect motor vehicle occupants, containing a liquefied gas mixture in which the liquefied gas components consist of a mixture of one or more ethers, olefins, ammonia or hydrogen and nitrous oxide (N.sub.2 O).

A method for producing a caseless propellant charge is disclosed wherein a polynitro polymer having an aromatic or heterocyclic ring is employed as a binder with a solvent and a propellant to produce an admixture and the admixture is molded into a shaped charge body.

Polymer nitroaromatic compounds as propellants

An electrically primable igniter charge yield has a composition that yields a reduced proportion of toxic vapors after the deflagration. The composition of the charges contains, as the oxidizing agent, zinc peroxide and, as a component providing additional energy, initiating explosives of the kind which do not trigger a detonation in direct contact with press-molded elements of nitrocellulose propellant charge powders. Among these initiating exposives are the potassium salts of trinitrophenol or trinitroresorcinol. The components of the igniter charges are mixed with fibers of an electrically conductive material. Suitable conductive materials are carbon or metals, such as iron or copper, or metal alloys, such as brass, for example. The igniter charges furthermore contain a binder which is preferably a secondary explosive, such as, for example, nitrocellulose.

Electrically primable igniter charges for caseless ammunition and

A nucleus-nitrated aryl ether is produced by reacting an aromatic halogen-containing nitro compound with an aromatic hydroxy compound, which may be nitrated in the presence of a base. The ether may be an oligomer compound or a polymer and is suitable for use as an explosive or propellant charge.

Nitrated aryl ethers

A primer charge containing an oxidizing agent and an initiating explosive. The charge contains as the oxidant zinc peroxide and as the initiating explosive diazodinitrophenol and/or a strontium salt of mono- and/or dinitrodihydroxydiazobenzene. In correspondence with the content of the strontium salt employed, the charge can also be utilized with low tamping; alternatively, such tamping can be selected at will. The charge is furthermore distinguished by lead-free and barium-free combustion products so that the charge does not exhibit the properties which make the heretofore known primer charges deleterious to the health of humans.
