Any other information on results incl. tables

For thermal sensitivity, the material which has been tested is "copper chromate", the raw material of copper chromite ; this material is not explosive under influence of flame.

Copper chromite is obtained by calcination of "copper chromate". Then heating "copper chromate" during the test will produce copper chromite which is a stable species as shown by Differential Thermal Analysis (no detection of decomposition until 500°C).

It is concluded that copper chromite is not explosive under influence of flame.
