Back Cover: Ignition and Combustion Behavior of Sintered‐B/MgB 2 Combined with KNO 3 (Prop., Explos., Pyrotech. 6/2020)

Oxygen-flask combustion with light beam ignition.

A robust oxygen-flask combustion system was developed using light beam ignition. An appropriate amount of environmental sample was wrapped with a small piece of filter paper and held in a basket made of platinum-zirconium spiral. After the sample was inserted into an oxygen-filled flask containing an acid mixture, the light beam from an overhead projector lamp was focused to ignite the sample. ...

Deliquescence of NaCl – NaNO 3 , KNO 3 – NaNO 3 , and NaCl – KNO 3 salt mixtures from 90 to 120 °

We conducted reversed deliquescence experiments in saturated NaCl–NaNO3 – H2O, KNO3 – NaNO3 – H2O, and NaCl–KNO3 – H2O systems from 90 to 120 °C as a function of relative humidity and solution composition. NaCl, NaNO3 , and KNO3 represent members of dust salt assemblages that are likely to deliquesce and form concentrated brines on high-level radioactive waste package surfaces in a repository e...

Phase Changes in Boron Ignition and Combustion

The ignition of electrically heated boron filaments in air and argon/oxygen mixtures has been studied. Boron filament resistance, temperature, and emissions from the BO and BO2 bands were monitored. Preliminary experimental data have also been obtained to characterize the phases formed inside burning boron particles produced and ignited from the same filament material by feeding a vibrating bor...

A Study of Cavitation - Ignition Bubble Combustion

We present the results of an experimental and computational study of the physics and chemistry of cavitation-ignition bubble combustion (CIBC), a process that occurs when combustible gaseous mixtures are ignited by the high temperatures found inside a rapidly collapsing bubble. The CIBC process is similar to that in a diesel engine. However, the length scales are very small (μm to nm) and the t...
