The main conditions of the heating program were optimized,
and the follow temperatures were chosen: drying 1, ramp of 15 °C s−1
up to 90 °C and hold for 15 s; drying 2, ramp of 5 °C s−1 up to 130 °C
and hold for 10 s; pyrolysis, ramp of 15 °C s−1 up to 1300 °C and hold
for 20 s; atomization, ramp of 2000 °C s−1 up to 2400 °C and hold for
6 s; and clean out, ramp of 500 °C s−1 up to 2500 °C and hold for 3 s.
