The energetics of cast calcium sulfate dihydrate-aluminum thermites were investigated. The casts were prepared from water slurries with a solids content below 65 wt %. The base case thermite comprised 60 wt % calcium sulfate dihydrate as the oxidizer with 40 wt % aluminum as fuel. The heat of hydration of the base case was 83 ± 4 kJ·kg-1 (dihydrate basis) and the initial setting time was about 100 min. The compressive strength reached 2.9 ± 0.2 MPa after 3 days of drying in ambient air. The… 

Performance of Mn/Bi2O3 Pyrotechnic Time Delay Compositions

Chemical time delay detonators are used widely in mine blasting applications. In order to achieve effective blasting, detonations must follow a precisely controlled timing sequence in a specified

Effect of Cu2+ on the nucleation kinetics and crystallization of rod-shaped CaSO4·2H2O in aqueous solution

In this study, a simple and efficient strategy is developed to synthesize rod-like CaSO4·2H2O (DH) crystals with tunable aspect ratio in aqueous solution using Cu2+ as modifier. The aspect ratio and

Simultaneously Altering the Energy Release and Promoting the Adhesive Force of an Electrophoretic Energetic Film with a Fluoropolymer.

Energetic coatings have attracted a great deal of interest with respect to their compatibility and high energy and power density. However, their preparation by effective and inexpensive methods



Sulfates-based nanothermites: an expanding horizon for metastable interstitial composites.

These new kinds of nanothermites have outstandingly high reaction heats compared to conventional Al/metal oxides, and also have good combustion velocities which opens up new horizons in the domain of metastable interstitial composites.

Effects of the type of calorimeter and the use of plasticizers and hydrophobizers on the measured hydration heat development of FGD gypsum

Thermal phenomena at the hydration of calcium sulphate hemihydrate (CaSO4·0.5H2O) are investigated in the paper. Time development of hydration heat of β-calcium sulphate hemihydrate prepared from

Comparison of Performance of Fast–reacting Nanothermites and Primary Explosives

The main features of nano-sized thermites are reviewed with the purpose to compare the performance of most reactive nanothermites showing high combustion front velocities of up to 2500 m s−1 with

Parameters Influencing the Pyrotechnic Reaction

Phenomena (reaction effects) such as varied light emissions, sound, varied burning rates, varied heats of reaction and reaction products occur during the reaction of inorganic redox systems used for

"Green" pyrotechnics: a chemists' challenge.

This Review summarizes the sources of pollution in current formulations and recent efforts toward "green" pyrotechnics.
