Popis: | The wet and dry strengths of particulate (colloidal) silica gels have been studied. It is shown that these strengths are a function of particle size of the powders composing the sol, and the higher the surface area of the powders, the higher the strength values of the gels. Ageing the wet gels in moulds has no effect upon strength. The effects of binders and modes of preparation of the sols upon strength of the gels were also studied. |
