Flame Aerosol Synthesis of Metal Sulfides at High Temperature in Oxygen‐Lean Atmosphere
Advanced Materials, Volume 35, Issue 28, July 13, 2023., 2023 As proof‐of‐principle, the preparation of various metal sulfides in a flame process using single‐droplet combustion and enclosed flame spray pyrolysis in O2‐lean condition is demonstrated. Using a large‐tube reactor MnS, CoS, Cu2S, ZnS, Ag2S, In2S3, SnS, and Bi2S3 are formed at a rate of 5 g h−1.

Journal of Combustion, Volume 2022, Issue 1, 2022., 2022 Lean premixed (LPM) combustion processes are of increased interest to the gas turbine industry due to their reduction in harmful emissions. These processes are susceptible to thermoacoustic instabilities, which are produced when energy added by an in‐phase relationship between unsteady heat release and acoustic pressure is greater than energy ...
