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 properties: A physical property that will be the same regardless of the amount of matter. 1  density: Ï=mv. 2  color: The pigment or shade. 3  conductivity: electricity to flow through the substance. 4  malleability: if a substance can be flattened. 5  luster: how shiny the substance looks.
