摘要： The present invention provides highly dispersible precipitated silica having improved structure and properties for use as reinforcing filler in elastomeric compositions and method of preparation thereof. The present invention further provides an alkaline silicate solution having reduced dielectric constant by digesting biogenic silica source with alkaline solution such that soluble organic compounds present in the biogenic silica source leach into the alkaline silicate solution. The alkaline silicate solution obtained as above is then acidified with a mineral acid under particular conditions of pH, temperature, time etc. to obtain the highly dispersible precipitated silica of the present invention.

摘要： A method of making a diatomaceous earth granulate may include spray-drying a suspension including particles of diatomaceous earth, a liquid medium, and a binder, wherein inorganic solids in the suspension include at least 80 wt % diatomaceous earth. The method may further include recovering a diatomaceous earth spray-dried granulate. A granular diatomaceous earth product obtained by the method may include substantially spherical granules, each having a shell including diatomaceous earth surrounding a hollow core. The product may be used as a filter aid or in filtration.
