Abstract
Improvements in chromium dioxide particle properties and performance have been achieved by altering the synthesis process. Solubilization of seed crystal precursors during the paste premix stage of the process led to improved friability, dispersibility, and tape noise and outputs in audio and video formats. The improvements are attributed to the presence of fewer aggregates and to narrower crystal size distribution. Both factors accrue from the more uniform crystal growth conditions provided by solubilization of the seed crystal precursors.
