Crystals of potassium dihydroxide were measured by Schabus (Wien. Ak. Veg. 1850) and he also stated a very perfect cleavage along {001} and less perfect along {100} and {010}. Potassium dichromate from aqueous solutions (t = + 20° C.) is released in well-formed crystals with growth planes {001} or {101}, which, as is known, belong to the pinacoidal class of triclinic system of cubic type.
