Ballistite, attenuated

Ballistite 50/50, invented by Nobel, was manufd as propint for mortars. It was partially replaced by Attenuated Ballistite, which contd 25% NG and 15% DNT. The German name, Wiirfelpulver (WT), was assigned to Ballistite 50/50 used in mortars (Ref 44,... 

Another type of attenuated ballistite (WP) containing less nitroglycerine and an increased content of nitrocellulose was also produced in Germany. It consisted of ... 

During World War I and later attenuated ballistite (Ballistite ATT) in which the nitroglycerine was partly replaced by DNT was used in France. To prevent excessive attenuation the collodion cotton was partly replaced by high nitrated nitrocellulose (CP,) ... 

To obtain ballistite with a more progressive rate of burning, attempts were made to produce laminated flakes, with the two outer layers made of attenuated ballistite and an inner one, sandwiched between, made of ordinary ballistite. In the attenuated ballistite DNT was substituted for part of the nitroglycerine. However a powder of this type retained its ballistic characteristics for only a few months, since, due to diffusion, the composition of all three layers gradually became equal. 

ATT (Attenuated) Ballistite. A ballistite, claimed to be flashless,was made in France from a mixt of CP, (NC with ca 13% N) ... 

No 2(CP2), sol in eth-alc contg ca 12%N. A mixt of CP, CP2, colloided with eth-alc, was used to make Poudre B(See B Poudre). Either CP, or CP2 with NG was used to make Ballistite (qv) and both of them, with NG and non-volatile solvs, were used to make Attenuated Ballistite (See Vol I,p A506-L). Before WWII, Poudres SD (sans dissolvants or solventess powders) were prepd in France. These pdrs consisted of NC gelatinized with NG and without a vol solv. The so-called CPzSD(which stands for NC contg 11.6-11.7%N, without solvent)was used in some of these propints. The designation CP3, sometimes found in Fr literature, means NC with a N content to ca 11.5%(Refs 8,14,22 68)... 

An improved variety, called super attenuated, ballistite and used during WWl by the French...
