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? WebJun 1, 2014 · The results showed that the average crystallite size of HAp powder varies from 11nm to 177nm and respective crystallinity of powder found to be in the range of 0.12 and 0.92. The effect of these physico-chemical properties of HAp powders on human colon cancer HCT116 cells inhibition was determined in vitro.
