ABSTRACT:
Non agglomerating hollow sub-micron size, 0.5 to 2.0 um, indium oxide microspheres are produced using an aerosol pyrolysis method using an indium compound, preferably, an indium acetate precursor, which is dissolved in water, without the use of chlorine or other dangerous chemicals, to generate an indium constituent such as, acetate dihydroxy indium (III), formed in droplets which, when heated by furnace temperatures of 650-700.degree. C., form the indium oxide microspheres particles suitable for polymer loading as a polyimide matrix particularly useful as antistatic coatings.
