Sodium silie increases the pH of the suspension, due to hydrolysis, whereas the silicon separates out in the form of colloidal silica which also performs a role as protective colloid, according to the following reaction: Na 2 2 + H 2 O => nSiO 2 + 2Na + + 2OH. When used alone, the percentage in pastes varies between 0,3 and 0,7%.

In plants and mechanical engineering, alumina ceramics are mainly used for wear and corrosion protection. The particle size distribution largely determines the appliion range and the quality of an alumina powder. Reliably identifying the differences in particle size is therefore an essential requirement of the measuring instrument.
Dec 20, 2005 · Atomic force microscopy (AFM) has been used to measure the force of interaction between pairs of silica colloids in aqueous inorganic and natural organic electrolyte solutions. In solutions containing a mixture of mono and divalent inorganic ions, the force measurements on approach can be understood in terms of an electrical doublelayer interaction, with decay lengths being comparable to .
