Preparation of silica-coated calcium carbonates with increased surface and mesoporosity and hollow silica coatings obtained from them |
| abstract |
A process comprising: preparing an aqueous carbonate suspension comprising calcium carbonate particles; adding at least one silicate composition to the aqueous carbonate suspension to obtain a carbonate-silicate suspension; lowering the pH of the carbonate-silicate suspension by adding at least one acidic compound to obtain a pH-adjusted suspension comprising silica-coated calcium carbonate particles; and isolating the silica-coated calcium carbonate particles, wherein: the silicate composition comprises a silica and a metallic oxide; a molar ratio of silica to metal oxide in the silicate composition ranges from 1.1: 1 to 5: 1; the addition of the at least one acidic compound is controlled so that the final pH of the pH adjusted suspension ranges from about 7 to about 10; and the silica-coated calcium carbonate particles comprise a porous coating having a mean pore diameter ranging from 2 nm to 50 nm. |
