~ -- Nobel's powder, known as ballistite, originally consisted of a camphorated blasting gelatine, and was made of 10 parts of camphor in
In 1875 Nobel created blasting gelatin, a colloidal suspension of nitrocellulose in glycerin, and in 1887 ballistite, a nearly smokeless powder especially suitable for propelling military projectiles.
The leading representatives of this class of propulsive explosives, or 'smokeless powders' are ballistite and cordite, the technology of which will be found fully discussed in special manuals of the subject.
Smokeless powders came into use, the explosive properties of picric acid were discovered, and melanite, ballistite, and cordite appeared in the last quarter of the century, so that by 1890 nitrocellulose and nitroglycerin-base powders had generally replaced black powder as a propellant.
In the case of cordite, as also with ballistite, a considerable quantity of aqueous vapour has to be added to the permanent gases formed.
As might perhaps be anticipated from the higher heat of ballistite, its erosive power is slightly greater than that of cordite, while the erosive power of cordite is again slightly greater than that of brown prismatic.
The ballistite made in Germany contained more nitro-cellulose, and the finished powder was coated with graphite.
~ -- In the case of ballistite the treatment is the same, except that when it is in a very finely granulated condition it need not be cut up.
A gramme of ballistite generates 615 c.c. of permanent gases, and gives rise to 1,365 grm. units of heat.
Nitro-glycerine is also largely used in the manufacture of smokeless powders, such as cordite, ballistite, and several others.
