Abstract

PURPOSE:To produce superfine particles having extremely small particle sizes easily and efficiently by cooling quickly superfine particles of nonoxide ceramic obtd. by a gaseous phase reaction down to a temp. causing no more conglomeration. CONSTITUTION:Superfine particles of nonoxide ceramic are formed by carrying out a gaseous phase reaction. For example, when superfine particles of AlN is to be produced, AlCl3 as a raw material is evaporated by heating at 130 deg.C in an evaporator 1, and 600cm<3>/min gaseous He is bubbled therein. The gaseous He contg. 3.2mol.% AlCl3 is introduced into a reactor 3 installed with a cooler, and another gas contg. 15% NH3 is also introduced separately into the reactor. A gaseous phase reaction is carried out by heating the reactor at 800 deg.C with a heater 5 to form thus superfine AlN particles. The superfine particles obtd. by this method are brought into contact with a cooler 2 wherein air at room temp., etc., is fed preventing thus conglomeration of particles with each other. Obtd. superfine particles are then collected.
