WebDefinitions vary, but nanocrystalline material is commonly defined as a crystallite (grain) size below 100 nm. Grain sizes from 100–500 nm are typically considered "ultrafine" grains. The grain size of a NC sample can be estimated using x-ray diffraction. In materials with very small grain sizes, the diffraction peaks will be broadened. WebThe crystallite size of microcrystalline diamond films is typically >100 nm. Microcrystalline diamond films can now be produced at growth rates of tens of micrometers per hour and are widely used for many industrial applications.
