What kind of particle size is the volume average diameter [MV] in particle size measurement?

[MV] is the volume-weighted average diameter!

The volume average diameter refers to the "MV" value. However, it is important to note that the cumulative 50% particle diameter is often referred to as the average diameter. This cumulative 50% particle diameter should be referred to as the median or mid-diameter. Below are representative examples of characteristic values that describe the particle size distribution of powders. [10%, 50%, 90%] 10%, 50%, 90% (μm: micrometers) Assuming a collection of a powder, let’s say its particle size distribution has been determined. When the cumulative curve is obtained with the total volume of the powder population set to 100%, the particle diameters at the points where the cumulative curve reaches 10%, 50%, and 90% are referred to as the 10% diameter, 50% diameter, and 90% diameter (μm), respectively. In particular, the 50% diameter is commonly used as one of the parameters to evaluate particle size distribution as the cumulative median diameter (Median diameter). *For more details, please refer to the related links or feel free to contact us.
