what process agents like toluene, deionized water etc. added to avoid the sticking of tio2 powder?
kindly suggested the optimized process parameters for tio2; like- ball to power ratio, ball size, rpm, time etc .
Good day, Khushneet Singh! Hope you are doing well.
I suppose you should follow the methodology, provided here:
Article Frequency and temperature dependent electrical characteristi...
"CaTiO3 ceramic powders were prepared by high-energy ball milling technique. In this technique, CaO (99.9%) and TiO2 (99.95%) were used as starting materials. Stoichiometric amounts of these materials were weighed. The high-energy ball milling of these weighed powders was done in Retsch High Energy ball mill. Initially, the weighed powders were mixed in tungsten carbide vial with tungsten carbide balls (10 mm in diameter) as milling media for 30 min at 100 rpm. The ball-to-powder ratio (BPR) was maintained at 20:1 by weight. Then it was increased to 300 rpm and high-energy milling was started. It was observed that the dry milling was not suitable for these materials because of sticking of powders to the walls of vials. To avoid this problem, toluene was added as a medium which also acted as a coolant and facilitated proper mixing of the powders during milling."
Best of luck in your research!
