A PYROTECHNIC COMPOSITION FOR THE ENERGY RICH PROPELLANT AND THE PROCESS FOR THE PREPARATION THEREOF

摘要

This invention relates to a pyrotechnic composition for energy rich propellant comprising magnesium powder as metal fuel and present in the amount of 22 to 50% by weight preferably 37 to 47% by weight, potassium nitrate as an oxidizer and present in an amount of 70 to 42% by weight preferably 55 to 45% by weight, and the remaining is 8 to 10% of binder as a solution of plasticised ethyl cellulose (PEC) in toluene and further according to this invention there is provided a process for the preparation of pyrotechnic composition for energy rich propellant which comprises in the steps of preparing a mixture of 22 to 50% by weight of magnesium powder with purity higher than 95% and 70 to 42% by weight of potassium nitrate, mixing 8 to 10% PEC solution with a mixture of magnesium powder and potassium
