Precooling rate and reduction temperature effect on the characteristics of molybdenum powder by a novel freeze-drying method

Key Points

• The aim is to determine how different precooling rates and reduction temperatures impact the characteristics of molybdenum powder.
• Used freeze-drying to analyze the effect of cooling rates on ammonium paramolybdate powder morphology.
• Examined variations in reduction temperatures regarding size, morphology, and structure of the powder.
• Conducted systematic discussions based on experimental findings.
• Found that different precooling rates significantly altered the powder's morphology.
• Showed that reduction temperatures influenced the size and structural characteristics of the powder.
• Demonstrated a clear relationship between processing conditions and powder quality.
