Abstract
Ultrafine chromium (III) oxide powders have been produced by laser-ind uced pyrolysis of chromyl chloride vapour. The crystalline particles a re characterized by their mean diameter, which is found to be between 10 and 300 nm. This is determined as a function of the parameters of t he reaction. The pressure in the reaction chamber, focusing the laser beam or using different carrier gases has a significant influence on t he mean particle size. Variation of the laser power and of the flow ra te of the carrier gas does not influence the particle size. (C) 1998 E lsevier Science S.A. All rights reserved.
