Raw powder and solvating media (such as water) are fed into a mill with ceramic balls. This ball mill is then rotated or shaken to create a uniform mixture (called a slurry), with evenly distributed particles of various sizes. Adjustments are made by adding raw powder and binder dispersants throughout this process.
