The Monitoring of Crystallite Size By an X-Ray Method Applicable to the Processing and Synthesis of Micron-Sized Powders
An X-ray method for determining the crystallite size of powders is presented that aids in a quick monitoring of powder processing and synthesis of micron-sized powders. The method is helpful in the range of tens of microns to micron sizes. The excellent counting statistics of the X-ray method compares favorably over microscopic methods in its efficiency and ability to characterize the powder in terms of its crystallite size. An albite (NaAlSi3O8) powder that originally showed a distribution of grain sizes was ball milled to a uniform micron size and micron-sized forsterite (Mg2SiO4) was synthesized by a solid-state method using ball milling for mixing of reactants.
