Small‐Scale Detonation of Industrial Urea‐Hydrogen Peroxide (UHP)

Abstract The adduct of Urea and Hydrogen Peroxide (UHP), also called Carbamide Peroxide, is industrially produced as a solid source hydrogen peroxide for bleaching, disinfection, oxidation reactions. As chemical combination fuel oxidiser, UHP has explosive potential but it unclear whether could sustain detonation at small scale. In the configuration we tested, succeeded in recording self‐sustained relatively scale under heavy confinement, measuring maximum experimental velocity 3860 m/s an optimum 1.1 g/cm 3 loading density. can detonation, even 100 g scale, this strongly dependant on booster size, confinement material, density, charge length diameter. According to our performance assessment, pure exhibits behaviour non‐ideal tertiary explosive. Maximum calculated pressures are below 10 GPa, order magnitude commercial blasting explosives. Small‐scale results consistent with literature values from large‐scale experiments, although matter quite limited. proposed method be used quantify detonability other industrial materials that may have energetic properties, or samples homemade compositions, avoiding time‐consuming, expensive potentially hazardous experiments.
