The third phase of the Arsenal s development began with an appropriation in 1906 of 165,000 for the erection and equipage of a powder factory. This work was undertaken by Major B.W. Dunn, Jr, the inventor of Explosive D , which replaced Maximite for armor-piercing shell. 

In 1907 this, the Army s first powder factory, was constructed. It was at this time also, and in line with its expanding activities, that the name was Finally changed to Picatinny Arsenal...

This powder was so successful that it was adopted not only in Russia (in preference to Vieilles Poudre B , developed in Fr), but also by the US Navy. Its introduction in this country was due to Lt. Bernadou, US Naval Attache in St. Petersburg at that time. Soon after its introduction in the USA (1395—96), the powder was manufd at the Naval Powder Factory, Indian Head, Md. lt should be noted that Bernadou improved the powder by using NC with a slightly higher N content (12.6—12.7%), and this became known as Pyrocellulose Powder . Its use by the US Army began about 1899...

Escales [56] gives the following figures characterizing the influence of duration of kneading on the density of the product (according to data obtained from the powder factory at Spandau). 

The more modem approach to the problem of mixing nitrocellulose consists of mixing defined types of nitrocellulose in the nitrocellulose factory itself. In this case the two forms of nitrocellulose are mixed under water in mixers as described in Vol. II, p. 374. The water is then centrifuged and the mixture dehydrated with alcohol. This method, however, creates certain inconvenience to the powder factory which loses the possibility of changing (within certain limits) the composition of the mixtures, i.e. nitrogen content and total solubility of nitrocellulose. The powder factory is therefore compelled to limit the number of factors which can be varied to obtain the powder of required ballistic properties. 

At the Troisdorf powder factory near Cologne, lead towers sprayed inside with sulphuric acid were used for the absorption of the solvent. Air containing alcohol and ether entered from below in counter-current to the sulphuric acid. 

Initially, adsorption with charcoal was not efficient when used as a main installation in nitrocellulose powder factories. With the high concentration of alcohol and... 

A number of unexplained accidents were encountered in nitrocellulose powder factories associated with handling alcohol and particularly ether.

The distance between the buildings should be large enough to prevent transmission of a fire from one building to another. A typical lay-out of a powder factory is given in Fig. 277.

About 1900 the Navy Department built the Naval Powder Factory at Indian Head, Maryland. The plant was capable of producing several thousand pounds of smokeless powder per day, and was enlarged during the course of a few years to a capacity of about 10,000 pounds daily. About 1907 the Ordnance Department, U. S. Army, built at Picatinny Arsenal, Dover, New Jersey, a powder plant with a capacity of several thousand pounds per day.

Hexanitroethane gives a lead block expansion of 180 cm3. It is more difficult to explode by impact than picric acid. With TNT or tetryl (in stoichiometric ratio) it forms exceptionally powerful explosives. Since it has the ability of gelatinizing nitrocellulose the Koln-Rottweil powder factory [89] tried to use it as a smokeless powder component to increase the explosive power of the latter. However, because of the high production costs of hexanitroethane, it has not found a practical use. In addition, its chemical stability is rather low when heated it begins to decompose at 75°C.
