Example 1;

NC. equal -ye Ich en N-Gehaits, but with the largest possible specific surface area is achieved by vigorous stirring in a lot of water evenly distributed and so much copper acetate dissolved in it that by slowly adding dilute sodium hydroxide solution at the same time Stirring so much copper hydroxide is gradually deposited finely on the NC fiber that after drying the desired Copper content is reached. It is of particular importance that no excess caustic soda is used and the NC treated in this way is washed out well, since excess sodium hydroxide solution could lead to the formation of soluble cuprates.

Example 2:

As in Example 1, but using lead (II) acetate.

Example 3:

As in Example 1, except that the modifier is in the form of copper (I) and copper (II) sulfide by introducing hydrogen sulfide is colloidally precipitated from neutral aqueous solution. By The colloidally dissolved copper sulfides are cooked in the finest possible way Form deposited on the NC.

example 4:

As in Example 3, but using lead (II) acetate.

Example 5:

As Example 1, except that is achieved the precipitation of finely divided basic copper acetates to NC by evaporation of the solvent, water under vacuum at temperatures up to 5O ⁰ C.

DB-FTS, which were produced with NC treated according to the invention, clearly showed the intended effect of a modified one Dependence of the burning rate on the pressure in "To the extent that they are finely ground with conventional addition Modifier salts was not achievable. In addition, there was a significant increase in explosion heat compared to DB-FTS are recorded in which finely ground modifier salts the same percentage was incorporated in a conventional manner by kneading and rolling. Other properties such as chemical stability and mechanical strength were within the usual range for DB-AGVs.
