For example, solid microspheres can be prepared by softening irregularly shaped particles just enough for them to flow into spheres under the influence of surface tension, by quenching a melt in a cooler medium, or by carrying out polymerizations in well-stirred suspensions at elevated temperature. Hollow inorganic microspheres can be prepared by several known methods.
- hollow glass spheres can be prepared by grinding and sizing soda-lime glass cullet to form particles that, in combination with blowing agents, are passed through a gas flame to soften the glass and generates gases that expand the particles. See Beck et al., U.S. Patent No. 3,365,315 . Hollow glass spheres can also be prepared by spray-drying a sodium borosilicate solution containing a blowing agent to form a particulate material that is passed through a gas flame to form the spheres. See Veatch et al., U.S. Patent No. 2,978,339 . Ceramic microspheres can be obtained as both solid and hollow microspheres as a normal aluminosilicate by-product of burning coal.
