Here is a brief look at how precipitated silica is made: Step 1: Precipitation. Sodium silicate solution (water glass) and mineral acid are reacted in an agitated vessel to produce a slurry of amorphous silica particles.
An intensive property is a physical quantity whose value does not depend on the amount of the substance for which it is measured. For example, the temperature of a system in thermal equilibrium is the same as the temperature of any part of it.
Intensive farming means large inputs (like labor and money) per amount of land, extensive farming means a low-input system with less labor and less expenses.
