Abstract

In the Belousov-Zhabotinsky reaction system bromide ions are generated periodically. When AgNO3 solution was added to this system, AgBr grains were prepared and the periodical pBr oscillation was sustained during addition of the solution. In previous research we added drops of AgNO3 solution synchronously to the pBr oscillation. This time we added AgNO3 solution by continuous flow and observed the pAg (pBr) oscillation and grain shapes. The periodical pAg oscillation was also sustained. At some addition rates, dendrite grains with four, five, six, or eight long branches were formed. In some grains, secondary nucleation took place on the surface of branches and many warts aligned. We believe that the grain corners grew preferentially.
