Abstract
:1. Introduction
2. Materials and Methods
3. Results
3.1. Powder Characterization
- Under the vacuum at 120 °C, the powder mixture reacts with the aluminum crucible.
- Under air at 100 °C, powder projections were observed.
- Under air at 120 °C, an exothermic reaction took place, leading to the combustion of the plastic container and a large part of the powder, the rest being projected on the walls of the oven.
