Materials Data on CrC6N12(ClO3)3 by Materials Project

CrC6(N2O)6(ClO)3 crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of eighteen hypochlorous acid molecules and six CrC6(N2O)6 clusters. In each CrC6(N2O)6 cluster, Cr3+ is bonded in an octahedral geometry to six equivalent O2- atoms. All Cr–O bond lengths are 2.03 Å. C4+ is bonded in a 1-coordinate geometry to two N+0.50- and one O2- atom. There is one shorter (1.34 Å) and one longer (1.35 Å) C–N bond length. The C–O bond length is 1.25 Å. There are two inequivalent N+0.50- sites. In the first N+0.50- site, N+0.50- is bonded in a distorted single-bond geometry to one C4+ atom. In the second N+0.50- site, N+0.50- is bonded in a distorted single-bond geometry to one C4+ atom. O2- is bonded in a bent 120 degrees geometry to one Cr3+ and one C4+ atom.

Barium Chloride Based Pyrotechnic Compositions for Green Color Emissions

Here, we present research focusing on the green light emission using Barium chloride dihydrate (BaCl2.2H2O) as an emitter contrary to commonly used Ba(NO3)2, Ba(ClO3)2, BaCO3, etc. For this work, different compositions containing BaCl2.2H2O and other components acting as oxidant, fuel, etc. were made and analyzed using TGA and burning tests. The flame intensity was captured using a photocell attached with a green color filter. It was observed that the decomposition behavior and the flame intensity were strongly influenced by the ratio of barium chloride to the oxidizer and by the particle size of the pyrotechnic composition powder. Compositions having a higher amount of oxidizer were found to decompose faster and have a more intense flame color.
