Augendre Powder, also called American Powder or White German Powder (Poudre blanche allemande or Teutonite, in Fr). The original mixt patented in France in 1849 contained KC103 48-50,K4FeCy6 25-29, sugar 23-25%. It was intended as a replacement for black powder as a propellant, but proved to be too sensitive for this purpose. If found use, however, in primer compns and percussion caps. The modified compn KCIO, 41.7, K FeCy 25.0, sulfur (or sugar) 20.8,...

Figure 23—1.) Six years later, a German scientist at IG Farben-Industrie, Max Fischer, was attempting to synthesize lube oils from ethylene. He tried a catalyst of aluminum powder and titanium at low pressures and ended up with a solid, white, wax-like material—polyethylene again.

In 1779 Peter Woulfe examined this mineral and concluded that it must contain something new. The Spar of the Germans, said he, is commonly called white tin ore.. . . This is supposed by several to be rich in tin but the Saxon mineralogists assert that it contains none. The only experiment I made with it was to digest it in a powdered state with acids, by which means it acquires a rich yellow colour, like turbith mineral [basic mercuric sulfate] the acid of salt answers best for this experiment. This is the only substance I know of which has this property (65). 

Melamine diborate (MB), known in the fire-retardant trade as melamine borate, is a white powder, which can be prepared readily from melamine and boric acid. It is partly soluble in water and acts as an afterglow suppressant and a char promoter in cellulosic materials. Budenheim Iberica79 claims that, in a 1 1 combination with APP, MB (10%-15%) can be used for phenolic bound nonwoven cotton fibers. In general, melamine borate can be used as a char promoter in intumescent systems for various polymers including polyolefins or elastomers. However, its low dehydration temperature (about 130°C) limits its application in thermoplastics that are processed at above 130°C. Melamine borate is also reported to suppress afterglow combustion in flame-proofing textiles with APP or monoammonium phosphate to meet the German DIN 53,459 and Nordtest NT-Fire 002.80...

Cocaine as it is known today—in a synthesized form— was first isolated from the coca plant in 1855 by a German chemist named Albert Niemann. A paste is made from the leaves of the plant. Then this paste is heated with hydrochloric acid to produce cocaine hydrochloride. This is the most common form of cocaine the white powder that is separated into fine lines, a few inches long, and then inhaled into the nose. When it is found in powder form, its purity can be anywhere from zero to 90 percent pure. In the form known as crack or rock, it is generally 25 percent to 40 percent pure.
