Coating of alumina onto the surface of hollow glass spheres was accomplished by controlled heterogeneous precipitation from aqueous solutions The processing conditions were optimized to yield thin and uniform precursor coatings. After calcination, converting the precursor to alumina, the alumina-coated hollow glass spheres formed free-flowing powders that were used to produce glass sphere/alumina matrix composites with up to 35 vol% of controlled and well-dispersed closed porosity. The dielec. constants and the flexural strengths of such porous composites were determined as a function of porosity.

The effects of the orifice geometry and hydrostatic head on drop formation were measured. The flow rates of hydrated aluminum sulfate melt through bores of 0.08 and 0.11 cm were measured for liquid heads of 10-100 cm. It was found that the break-up of a liquid jet produced particles in the size range 2.0-2.5 mm with a 0.8 mm orifice.

The structure and composition of the porous anodic oxide films of Al (abbreviated AOFAl) formed in oxalic acid (I) and H2SO4 (II) solutions, resp., were studied by TEM, IR and TGA. The porous anodic oxide films consist of a large number of hexagonal cells with an irregularly round pore in the center of each cell which penetrates vertically from surface to bottom, while a barrier layer under the film directly contacts with an Al substrate in a scallop shape. The content of Al2(C2O4)3 and Al2(SO4)3 in AOFAl (I) and (II) are ∼4.9% and ∼14.2%, resp.; ∼3.5% H2O of crystallization of Al2(SO4)3.xH2O which can be evolved at rather low temperature (∼85°) enriches between the cells and under the barrier layer of AOFAl (II); after irradiation by the electron beam of TEM the H2O of crystallization is removed and voids are formed.
