Crystallite size and particle size
WebJan 30, 2024 · Particle sizes are measured in microns (μ). A micron is 1/1000 mm. or 1/25,400 in. A millimicron (mμ) is 1/1000 of a micron, or 1/1,000,000 mm. Usually particle size is designated as the average diameter in microns, although some literature reports particle radius. What does crystallite size depend on?
