Abstract

Prodn. of hollow porous microspheres (A) comprises first feeding a stable dispersion of particles (B) in a film-forming compsn. to the outer ring of a coaxial nozzle while blowing gas through the inner ring. The hollow microspheres recovered have stable film walls and are treated to bring (B) into point-to-point contact so that hardening to green microspheres occurs. These are heated (1) to eliminate the continuous liq. phase and (2) to sinter (B) at their contact points, forming within the walls interconnecting voids, continuous between the outer and inner wall surfaces. The final prods. have uniform void content and distribution, and pref. also uniform dia. and wall thickness. (A) and the intermediate green microspheres are also claimed as new prods.
