Environmental Ageing of Basic Copper Nitrate

In the world’s leading pyrotechnic airbag technology, a rapid reaction between Basic Copper Nitrate (BCN, Cu2(OH)3(NO3)) and guanidine nitrate produces nitrogen gas, which inflates the airbag—producing life-saving results. Like most inorganic materials, BCN particles will coarsen when exposed to temperature and humidity over time. However, there is a lack of information available characterizing the impact of this coarsening process of BCN particles.

The results provided in the PDF below and to the right provide a framework for understanding how humidity and temperature affects the physical properties of BCN, and specifically surface area. Preliminary results on how packaging and changes in particle preparation can permit BCN material to resist ageing are also presented.
