Development of pyrotechnic delay mixtures based on a ...

variety of energy-intensive compositions, delay pyrotechnic compositions are of great interest, which serves to create time delays of the required duration [8-12]. The need to ensure a time delay in the operation of pyrotechnic products arose with the appearance of black powder and the first powder bombs, hand grenades and rockets.

Chemistry of Pyrotechnics, Conkling - PDF Free Download

In addition to an oxidizer, pyrotechnic mixtures will also contain a good fuel - or electron donor - that reacts with the liberated oxygen to produce an oxidized product plus heat. This heat will enable the high-energy chemist to produce any of a variety of possible effects - color, motion, light, smoke, or noise. 64 Chemistry of Pyrotechnics

Louder Boom with less Oxidizer

fuel and not more Oxidizer,its 66%-33% at 2;1 ratio a 50/50 mix will. give a brighter flash, adding sulfur [ 50/25/25] stretches the dollar. and antimony or hercules red dot give louder reports,so I'm told, I. prefer a Bright Flash and therefor use Ti sponge or flake. sometimes,and sometime finish with a 3" 50/25/25 shell,just to save.

Richard Nakka's Experimental Rocketry Site

This is an illustration of what is referred to as a pyrotechnic igniter which was used for igniting the B-200, C-400 and similar sugar-propellant rocket motors.It consists of a length of polyethylene plastic drinking straw filled as shown with a charge of Ignition Powder, and as such, is often referred to as a "straw igniter".. The igniter is sealed at both ends with polyethylene …

Flash Powder is a pyrotechnic composition or mixture made of a oxidizer and a metallic fuel. Optionally a "sensitizer" can also be added to the mixture. Flash Powder is static sensitive, friction sensitive, and impact sensitive.

How to Make Black Powder (and other explosives)

Sulfur will burn, albeit very slowly. The addition of an oxidizer (such as KNO3) greatly speeds up the burn rate of the fuel, resulting in an explosive reaction. The traditional ratio of the ingredients is 15:3:2 of KNO3, Charcoal and Sulfur by weight (not volume!). However, simply mixing the dry ingredients together will not give you black powder.

Milling Black Powder - Pyrotechnics - APC Forum

Milling Black Powder - posted in Pyrotechnics: Just wanted to get a poll on varying options of most efficient yet safest way to mill black powder without a ball mill. I used to use a coffee grinder however the last time I milled some I resorted to a mortar and pestle instead, which was far too much work. I know ball milling is the most common for large quantities.
