摘要: A method of preparing a particulate material comprising the steps of adding silicic acid solution, optionally doped with aluminum, optionally added to a slurry of pre-existing nanoparticles at a neutral to slightly acidic pH of no more than seven, and at a temperature of about 20° to 30° C. This yields a polysilicate particulate dispersion. Then, the pH of the dispersion is raised to greater than seven, to stabilize/reinforce particles of the particulate dispersion. Optionally, the particles may be dried, and have increased porosity and surface area.
