Fine silica gel, prepared by grinding coarse granules to a particle size < 100 μm, is heated in air at 100, 500, 600, 700, 800, 900, 1000, 1100, 1300, and 1400°C for 3 h. Pore structure is studied from variations in specific surface area, total pore volume and the mean hydraulic radii of the pore system available for nitrogen adsorption. These parameters are related as far as possible to changes in pore size, the distinct phases produced at each temperature, and the particle size of the… CONTINUE READING
