Esplosivi alti (High Explosives) o Esplosivi dirompenti (Brisant Explosives). To these belong Esplosivi da guerra, such as Tritolo (TNT), Pentrite (PETN), T4 (RDX), Melinite (PA), Tetrile (Tetryl), etc and Esplosivi da mina, such as listed in Tables I III and under DINAMITI, Items a, b, c, d, e, g, h, i, j, k, 1, m, p q.

Stettbacher, quoting the work of Langhans (Ref 2), stated that Aurum fulminans is the most ancient brisant explosive known and that manipulation with it in the past caused many serious accidents. For example, the famous Swedish chemist Baron J.J. Berzelius (1779— 1848) lost both eyes while working with FG (Ref 2, p 330)... 

Note. Dynamites I III, as well as the above Brisant Explosives, can also be used in non-gaseous coal mines. They are listed in Belgian Regulations as Type 1 Non Safety Mines Explosives... 

I960) as GerP 1031700. This DAS deals with prepn of a smokeless propellants and brisant explosives, now known as Holtex (See Ref 7 under Colloidal Explosives). All of these compositions were invented by Dr. E. von Holt (Dr. H. Freiwald, private communication, 25 Sept 1962)... 

By acidifying the hydrolysis mixture with sulfuric acid and by fractionating the product, Curtius procured anhydrous hydrazoic as a colorless liquid which boils at 37°. Hydrazoic acid is intensely poisonous and bad smelling. It is easily exploded by flame, by a brisant explosive, or by contact with metallic mercury. The anhydrous substance is extremely dangerous to handle, but dilute solutions have been distilled without accident.

Phlegmatized and pressed Cyclonite is used as a highly brisant material for the manufacture of -> Booster and -> Hollow Charges. Non-phlegmatized Cyclonite in combination with TNT is also used as a pourable mixture for hollow charges and brisant explosive charges (-> Compositions fi) mixtures of Cyclonite with aluminum powder are used as torpedo charges (Hexotonal, Torpex, Trialen). Cyclonite may also be used as an additive in the manufacture of smokeless powders. 

Loading density is a very important parameter, both in propellant powders (owing to the necessity of ensuring the strongest possible propellant effect in the loaded chamber, whose shape and size are mostly limited by the design of the weapon) and in brisant explosives (- Brisance). 

A highly brisant explosive is required for this purpose. Mud caps are usually covered with mud in order to enhance their brisance. It is often desirable to use charges of definite shape (-> Shaped Charges-, -> Cutting Charges). 

PETN is one of the most powerful and most brisant explosives, its -> Stability is satisfactory, and its -+ Sensitivity is not extreme. It is used in high-efficiency blasting-cap fillings and detonation cords. If phleg-matized with a small amount of wax and pressed, it may be used to produce boosters and fillings for smaller caliber projectiles. PETN can also be incorporated into gelatinous, industrial explosives (e.g., for seismic prospecting).

Although there seems to exist a coherence between performance and sensitivity (we give a lot of examples), the more brisant explosive being also the more sensitive one, there is no fundamental law that the gain in performance has to be paid with a loss in security. This can be verified by a few considerations An explosive single crystal is not detonable...

The separation may be accomplished in several ways. One way is condensing the ozone out as a liquid at a low temperature and then pumping off any oxygen that condensed along with the ozone this presents the hazards of handling concentrated liquid ozone, a touchy and brisant explosive.
