不同还原剂参与模式的超细钨粉制备技术研究进展
Research progress on the preparation of ultrafine tungsten powder with different reducing agent participation modes
摘要
Abstract
Ultrafine tungsten powder is a key raw material for high-performance tungsten-based products.However,most preparation methods remain confined to the laboratory scale,limited by low efficiency,operational safety risks,and high production costs.This review focuses on the hydrogen reduction of tungsten trioxide(WO3),analyzing its underlying reaction thermodynamics and kinetics.Preparation technologies are systematically categorized into two types based on the use of external reducing agents:"non-reducing agent participation"and"single reducing agent participation",with their fundamental principles,advantages,and disadvantages elaborated.Critical challenges—including difficulties in controlling particle size and morphology,hydrogen explosion risk,high energy consumption,and carbon contamination—are addressed,alongside proposed solutions such as process innovation,doping strategies,and atmosphere optimization.Finally,development directions toward greening and intelligentization are outlined to broaden the research perspective for large-scale production.关键词
