Abstract

Stable phase III potassium nitrate esp. for ferroelectric memory cells is prepd. by (a) melting pure potassium nitrate under vacuum, (b) evaporating the molten potassium nitrate under vacuum (c) precipitating the vapours in the form of a thin layer, and (d) reducing the vacuum to atmospheric pressure and the temps. to room temp. while maintaing a moisture-free atmosphere. The pdt. has ferroelectric, and light transmitting and polarising properties.
