Abstract
Chromium dioxide was synthesized by a sealed tube reaction starting from CrO3 and CaCl2.2H2O. Yields of CrO2 upto 90 percent could be obtained with 7 mole percent of CaCl2.2H2O at 360°C for 24 hrs. An ambient pressure of about 30 atm is estimated to be produced by the gases and vapours emitted during the reaction. Under certain conditions, acicular particles with length to width ratio of ~10 (constituting ~75 percent of the particles) were produced by this procedure.
