[Abstract](27767) [HTML](571) [PDF 1.13 M](8561) [Cited by](75)

Abstract:
The thermal decompositions of two kinds of NH₄ClO₄ (AP) with different grain size were investigated by DTA and TC-FTIR coupling. It is proposed that the decomposition of AP crystal obeys the process of “topochemistry ” and it is explained that there are two steps in the decomposition of the coarse grain size. On the basis of the gaseous products identified by real-time and rapid-scan FTIR and reported results in the literatures, the different mechanisms of the two steps during AP decomposition process are suggested.

[Abstract](15016) [HTML](309) [PDF 1.20 M](8998) [Cited by](48)

Abstract:
The research developments of high-nitrogen energetic materials are reviewed. The synthesis and properties of some new compounds derivated from tetrazole and tetrazine,especially 3,6-dihydrazino-1,2,4,5-tetrazine(DHT),3,3′-azobis(6-amino-1,2,4,5-tetrazine)(DAAT),3,6-bis (1H-1,2,3,4-tetrazol-5-yl-amino) -1,2,4,5-tetrazine(BTATz) and 5,5′-bitetrazole(BHT) are discussed. Because of their much more positive heats of formation and higher density，these high-nitrogen compounds are unique in their gas generating ability with a little or without smoke and produced residue. They may have a great future for applications in insensitive explosives,low signature propellants,gas generants and low-smoke pyrotechnics.

2000, 8(3):104-107.

[Abstract](14533) [HTML](537) [PDF 1015.52 K](5404) [Cited by](33)

Abstract:
On the basis of contact angle experiments, surface energies of TATB,HMX and four fluor-polymers were calculated by geometric equation,harmonic equation and Young-Good-Girifalco-Fowkes (YGGF) equation respectively. The values of surface energies obtained by YGGF equation are more credible than those obtained by the others. The calculated interfacial energies between TATB and fluor-polymers show that the latent Van der waal′s interaction between F₂₃₁₄ and TATB is the most powerful.

Abstract:
Catalytic activity of nanocrystalline transition metal oxides on the decomposition of energetic material NH4ClO4 (AP) is investigated by thermal analysis. Results indicated that the nanocrystalline CuO powders have most strongly catalytic activities comparing with other mono-metal oxides. Moreover, the catalytic activities of the nanocrystalline CuO powders on the decomposition of AP have relationship with preparing methods and the microstructure of nanocrystalline CuO powders. Among them, the catalysis of the spherical shape nanocrystal CuO powders with better dispersion on AP decomposition is the strongest, and it can made the higher temperature peak of AP decomposition drop down 93.19 ℃ and made thermal power rise to 1 420 J·g^-1 by 590.12 J·g^-1. Nanocrystalline Fe₂O₃ with doping with Cu²⁺(5%) can greatly enhance its catalytic activity on the decomposition of AP, and it made the higher temperature peak of AP decomposition drop down 78 ℃ by 35 ℃ (continuing dropping 43 ℃), and made thermal power rise to 1 230 J·g^-1by 980.50 J·g^-1. Compared with mono-metal oxides, some new multi-metal oxides have more strongly catalytic activities. Especially compound 1, it made the higher temperature peak of AP decomposition drop down more 110℃ and made thermal power rise to 1 470 J·g^-1.
