PRECIPITATED SILICA Precipitated Silica (also called particulate silica) is composed of aggregates of ultimate particles of colloidal size that have not become linked in massive gel network during the preparation process. It is an amorphous form of silica, the word amorphous denotes a lack or crystal structure, as defined by x-ray difraction.
Scale bar = 50 nm. aggregates are rather widely distrib-uted. Figure 3 is a TEM of collections of aggregates of common precipitated silica used in tire treads, Z1165. This TEM is at a lower magnification than Figure 2 so that approximately 30 ag-gregates can be seen. The key features

Light and X-ray scattering are used to examine the structure of two commercial precipitated silicas (Zeosil 1165 and Ultrasil 7005) and one developmental precipitated silica, Dimosil 288. All three products have a four-level hierarchical structure consisting of primary particles, aggregates, hard agglomerates and soft agglomerates, with Dimosil 288 showing the clearest evidence of the four ...
A method for producing precipitate silicon dioxide by using sodium bicarbonate to control a supersaturation degree comprises the steps of taking quartz sand and soda as raw materials, roasting, dissolving a sodium carbonate solution to prepare a sodium silicate solution, allowing the sodium silicate solution to react with a sodium bicarbonate solution, separating out a hydrated silicon dioxide ...
A process and system for removing heavy metals, fluoride, silica and other contaminants from large volumes of wastewater is disclosed. In the process, a wastewater stream containing the contaminant is treated with a chemical coagulant to create a particle having a diameter greater than 5 microns. Treated wastewater is passed through a microfiltration membrane which physically separates the ...
Herøya Industripark AS is one of the leading industrial parks in Norway. More than 80 different companies with over 2500 employees are located in the park. Herøya's task in the AlSiCal project is to be an industrial partner for the scale-up and industrialization of promising R&D results. We interviewed Rolf Olaf Larsen about the role of Herøya in the project.
removal of this novel precipitated silicate from the brine is discussed in the lead up to pilot scale trials. Pilot scale test rigs for such trials are being constructed that directly compare our NCaSilH approach to removing the problematic supersaturated dissolved silica species from a geothermal
