Ceramic microspheres

Adding large quantities of pozzolan, ceramic microspheres or nitrogen. These materials lighten the slurry because they have lower specific gravities than the cement. [Pg.1186]

Quartz microspheres are now manufactured in many countries, e.g. the Q-cel microspheres. Metal, metal oxide, metal salts, and ceramics microspheres have also been used to make syntactic foams, 57 60>. [Pg.75]

Experiment It will be clear that manufacturing ceramic microspheres in the manner described above is not possible within a classroom situation and it is also not advisable. However, it is possible to carry out a simple analogous synthesis which offer many possibilities for expansion. The idea was suggested to me by one of... [Pg.292]

The RF thermal plasmas are suitable tools for making oxide ceramic microspheres, either dense or hollow. The microstructure of the product can principally be influenced by the structure of feedstock materials and to a less extent by the plasma operating conditions. Highly porous raw materials and/or the presence of blowing agents facilitate formation of hollow spheres. By varying the process conditions, one can primarily affect the thermal history of particles, hereby the degree of evaporation. [Pg.224]

Still other ceramics are important in medicine. For example, they are used to febricate artificial bones and to crown damaged teeth. The feet that many ceramics can be easily sterilized and are chemically inert makes ceramic microspheres made of these materials useful as biosensors. Drugs and other chemicals can be carried within microsphere pores to desired sites in the body. SEE ALSO Glass Minerals Semiconductors Superconductors. [Pg.214]

Another approach to decrease slurry weight can be to add light solids like coal, asphaltite minerals, hollow glass, or ceramic microspheres. Finally, foams can be prepared using air or nitrogen and a cement slurry as the continuous phase to densities as low as 0.8 g/cm3 (24). [Pg.618]
