Ignition and combustion of dropping CuFeS2 particles characterized by high-speed visualization using temperature image

Key Points

• Ignition occurs rapidly as CuFeS2 particles drop, showing significant temperature fluctuations during the process.
• High-speed imaging captures temperature changes, revealing critical data on 450 Kelvin and higher during combustion.
• Analysis of particle interactions demonstrates the combustion characteristics of CuFeS2 under controlled conditions.
• Further study is needed to understand the broader implications for energy applications and material behavior.
