Research abstract
ULTRAFINE PARTICLES OR POWDER CAN BE PREPARED BY EVAPORATING MATERIAL INTO AN INERT GAS ATMOSPHERE. THE VAPOR IS COOLED BY THE INERT GAS AND BECOMES SUPERSATURATED, LEADING TO PARTICLE CONDENSATION. HOWEVER, CONVECTION OF THE INERT GAS IS A SEVERE PROBLEM, CAUSING THE PARTICLES TO COALESCE INTO A FEWER NUMBER OF LARGER PARTICLES. ANALYSIS SUGGESTS THAT PARTICLE PRODUCTION BY THIS TECHNIQUE IN MICRO-GRAVITY HAS UNIQUE ADVANTAGES. THIS EFFORT WILL: (1) INVESTIGATE APPROPRIATE HEATING METHODS, (2) ANALYTICALLY MODEL THE PARTICLE CONDENSATION PROCESS, AND (3) DEVELOP PARTICLE COLLECTION METHODS.
