Relating detonation parameters to the detonation synthesis of silicon carbide

Detonation synthesis of silicon carbide (SiC) nanoparticles from carbon liberated by negatively oxygen balanced explosives was evaluated in a 23 factorial design to determine the effects three categorical experimental factors: (1) cyclotrimethylene-trinitramine (RDX)/2,4,6-trinitrotoluene (TNT) ratio, (2) (Si) additive concentration, and (3) Si particle size. These factors were at low high levels as they relate detonation performance explosive solid Si-containing phases produced. velocity Chapman–Jouguet (C–J) pressure, which measured using rate stick plate dent tests, evaluated. Solid product mass, residual concentration x-ray diffraction analysis. The RDX:TNT ratio shown affect terms C–J pressure up 10% 22%, respectively. Increased reactants improved average SiC products 1.9 2.8 wt. %. Similarly, increasing RDX TNT further oxidized reduced remaining after 8.6 A 70:30 mass mixture loaded with 10 % < 44 μm powder produced an estimated 1.33 g nanocrystalline cubic 150-g test charge. Using lower added finer size yield residue 0.38 yet 1.64:1.
