Abstract
The aerosol synthesis method was applied for submicrometer ceramic Bi-Pb-Sr-Ca-Cu oxide powder preparation. The aerosol was generated from nitrate precursor solution using ultrasonic atomizers operated at 2.5 and 1.7 MHz. Control over the particle structural properties is established by adjusting the solution and process parameters. Improved compositional homogeneity, as well as, particle size and shape uniformity is provided by higher surface reaction and an absence of coalescence process during spray pyrolysis. The phenomenon of funicular agglomeration in ultradispersed multicomponent powders was explained by the mechanism of particle formation in the presence of liquid phase. The interparticle sintering observed for the prolonged thermal treatment is a result of highly reactivity powders obtained.
