Because of its unique grinding motion, the XRD-Mill McCrone is particularly effective for this analytical method: The 48 cylindrical grinding elements grind the samples gently via friction. The result is a short grinding time with almost no sample loss and an exceptionally narrow particle size distribution.

then further reduced in a McCrone micronizing mill until most particles (as assessed with the light microscope) were <20 pm (with the majority <5/Am). Stock suspensions (20 mg/mL) in physiological saline were prepared by ultrasonic dispersion and further dilutions of these suspensions (resuspended by ultrasonication as necessary) were prepared as
The XRD-Mill McCrone was specially developed for the preparation of samples for subsequent X-ray diffraction (XRD). The mill is used for applications in geology, chemistry, mineralogy and materials science, quality control as well as R&D.
In the McCrone mill a volume of >1 ml is usually required, although desperate scientists have been known to dilute the specimen with amorphous material, such as silica gel. The analyst should also be aware of the possible contamination of samples by degrading and eroding grinding elements (corundum or agate in the micronizing mill; possibly ...

To avoid amorphisation of the sample during grinding, wet milling is done in a McCrone Micronizing mill. Before grinding in the McCrone Mill, the samples are crushed and passed through a 500 micron sieve. Take representative amounts of sample (50-100 g). Crush the sample by hand in a porcelain mortar. Use shock impact for grinding, avoid shearing.
ratory‐made McCrone type micronizing mill for 5 minutes. After evaporation of the alcohol, diffractograms of the sam-ples were collected on a D2 Phaser diffractometer (Bruker) using CuK α radiation operating at an acceleration voltage of 30 kV and a current of 10 mA. The selected conditions were:
