Abstract

The whiskers which may be used in electronic devices as reinforcement for glass, metal and plastics or as filters are produced by crystallising in an atmos. contg. a gp. IIIB metal or cpd. but excluding La, at 2450 degrees C pref. 2200-2400 degrees C. Pref. crystallisation is effected by recrystallisation and/or condensation in an inert atmos. in a sealed silicon carbide container and in the presence of cerium or yttrium, pref. a mineral of high cerium or yttrium content. For electronics applications various elements-N, Al, B or P may be added during crystal growth to modify the conductivity or fluorescence.
