Learn More· The problem indicated in the application had to do with the need to regulate the size of the crystals by means of a wet ball mill process. According to the description, wet milling had proven to be difficult to carry out with use of the water-free crystal form described in the Base Patent. The difficulties were indicated to be due partly to wettability and partly to the …
Learn More· Macro material is filled into a ball mill or something similar and can be milled down as far as around 30 nm. The advantage is the low cost of the procedure. One disadvantage is, that the grain boundaries are still touching and stick strongly together. Thus these particles are very difficult to disperse. Additionally high mechanical forces applied to the material can lead …
