Method of preparing loosely aggregated 200-500 millimicron silica |
| abstract |
A loosely aggregated 200-500 millimicron primary particle size silica can be produced by a silicate neutralization technique. The process consists of neutralizing an alkali metal silicate solution by addition to an ammoniated acetic acid or carbonic acid mixture. These particles are loosely aggregated to an average particle size of about 1 micron. These particles are readily deaggregated in a fluid energy mill. A very convenient technique is to dry and deaggregate in a fluid energy mill in a single step. |
