Synthesis of [Pb(H2O)6][ATZ]·H2O and its impact on potassium nitrate decomposition temperature

In this study, catalyst formation [Pb(H 2 O) 6 ][ATZ]·H 2 O (ATZ = azo tetrazolium anion) was successfully synthesized originally; meanwhile, the single-crystal structure of the compound was cultivated and analyzed by diffraction single-crystal method. The influence of the compound in which [Pb(H 2 O) 6 ][ATZ]·H 2 O was used as combustion catalyst on the decomposition temperature of potassium nitrate was studied by TG–DSC. The result proved that [Pb(H 2 O) 6 ][ATZ]·H 2 O can effectively reduce the decomposition temperature. In other words, [Pb(H 2 O) 6 ][ATZ]·H 2 O can reduce the decomposition temperature of potassium nitrate, so the addition of [Pb(H 2 O) 6 ][ATZ]·H 2 O can make potassium nitrate better to be used in the fields of initiating explosive device and fire engineering.
