Fine-grained halide bodies are formed which have comparable optical properties to a single crystal halide body. The halide bodies are formed by press forging while an essentially constant fluid pressure is applied to the halide body.

Formation of halide optical elements by hydrostatic press forging

To obtain a compressed explosive charge of high density and low sensitivity, an explosive material having a bimodal grain size distribution is used, the coarse grain fraction having a mean grain size from 20 to 80 mu m and the fine grain fraction having a mean grain size from 2 to 10 mu m, the coarse grain fraction/fine grain fraction weight ratio being 3-10 : 1.

Process for producing compressed explosive charges

A method and a mould for manufacturing articles of compacted powder by isostatic compression of powder in a mould, which is made of flexible material of substantially constant thickness and is substantially barrel-shaped, the mould having at one end a bottom made integral with the rest of the mould and being adapted to be closed by a separate plug at its other end.

Method of manufacturing articles of compacted powder

The invention relates to a method for manufacturing explosives, especially propelling charge powder, from a stabilised explosive, especially a humidified stabilised explosive. Said method comprises dehydrating, gelatinising and processing the raw material to produce a granulated material by means of a shearing cylinder in a granulating device. The granulated material is formed into a block by means of an isostatic press, in a warm state and immediately after the granulation. Subsequent processing of the block is carried out in a conventional manner, e.g. by means of a hydraulic press.

Manufacturing of solvent-free propelling charge powder

Disclosed are an apparatus and method for loading small and medium caliber cartridges with pressable plastic bonded explosives (PBXs) A plurality of pellets are pre-formed to have a high density, and are loaded into a small and medium caliber cartridge one by one Accordingly, a high and uniform density is obtained And, when manufacturing small and medium caliber cartridges, the pressable PBXs are anticipated to be massively loaded into the small and medium caliber cartridges in the future
