GB/T 4195-1984
ActiveMethod for measuring the distribution of the powder size of tungsten and molybdenum method by the balance for the fall of the particles
钨、钼粉末粒度分布测试方法(沉降天平法)
Application Summary AI generated
This standard specifies the sedimentation balance method for determining the particle size distribution of tungsten and molybdenum powders. It is applied in the metallurgical industry, specifically for quality control and process optimization in the production of tungsten and molybdenum powders used in cemented carbides, electrical contacts, and high-temperature alloys. The method relies on measuring the settling rate of particles in a liquid medium to calculate the cumulative mass distribution.
