Abstract
A substantially cylindrical gas-generating pyrotechnical monolithic block has a thickness no lower than 10 mm, an equivalent diameter no lower than 10 mm, and a porosity lower than 5%; and a composition, given as weight percentages, which contains, for at least 94% of the weight thereof: +77.5% to 92.5% of guanidine nitrate, +5% to 10% of basic copper nitrate, and +2.5% to 12.5% of at least one inorganic titanate with a melting temperature higher than 2100 K.
Claims19
A gas-generating pyrotechnic monolithic block, of substantially cylindrical shape, wherein:
- the gas-generating pyrotechnic monolithic block has a thickness greater than or equal to 10 mm,
- an equivalent diameter greater than or equal to 10 mm, and
- a porosity below 5%;
- and
- wherein
- a composition of the gas-generating pyrotechnic monolithic block, expressed in percentage by weight, contains, for at least 94% of its weight:
- +77.5 to 92.5% of guanidine nitrate,
- +5 to 10% of basic copper nitrate, and
- +2.5 to 12.5% of at least one inorganic titanate whose melting point is above 2100 K.
