Testing of Safe, Barium Free Mixture for Green Flare

Abstract

The pollution caused due to fireworks is becoming one of the major problems in both environmental safety and human health. The greenhouse gases released during the burning of crackers cause global warming and eventually increase the temperature of the Earth’s atmosphere. The pollutants from burning the crackers cause health hazards in human beings. Particulate matter in the dust, such as PM2.5 and PM10, are easily inhaled by humans and affect human health. So, a new mixture with fewer pollutants and particulate matter compared to the existing mixture is formed with the help of Boron Carbide as fuel and Potassium Nitrate as the oxidizer. The newly formed mixture is completely Barium-free and is much safer to handle than Barium nitrate. Boron carbide is implemented in the smoke flare and was found to have the same performance as the existing composition. Therefore, an alternative to Barium nitrate is proposed, and various tests are done for the new mixture.
