Crystal formation
At last a system that effectivly stops the formation of crystal
One problem in connection with silica suspensions is the forming of crystals after use. When the liquid in the suspension evaporates after preparation, the silica content is concentrated leading to precipitation of crystals which cannot be dissolved by adding new suspension. The crystals will be deposited in the polishing cloth which will have to be discarded.
We have developed a very efficient method of limiting the precipitation of crystals. According to this method, the evaporation of water is reduced and – something quite new – our colloidal silica suspension allows precipitated crystals to be redissolved thus prolonging the life of the polishing cloth.
