Habit Modification

When present in ethylene diamine tartrate (EDT) solutions in small concentration boric acid produces many crystallographic phenomena associated with specific adsorption on crystal faces; especially habit modification and growth inhibition. These effects are typical of those given, incidentally, by "growth improvers", and it is concluded that boric acid would be a logical choice for intensive testing as a flaw suppressor in the solutions from which large single crystals of EDT are grown.
