Abstract

<PICT:0934536/III/1> Spheroidal crystals of ammonium and potassium perchlorate are grown from saturated solutions by cooling or concentration in a rotating smooth cylinder 1. The scraper 3 situated 1 mm. from the wall of the cylinder and the balls 6 which are plastic-coated, so as to avoid grinding the crystals, prevent the crystals from contacting the container walls or each other and prevent corner growth.
