What are the differences in specific surface area and bulk density of silica produced by silica manufacturers?
The bulk density of silica is in grams per liter, representing the weight of one liter of volume. For example, 200 grams per liter means that one liter of silica weighs 200 grams; the specific surface area BET of silica is the total surface area per unit mass of material in square meters per gram. For example, 170 square meters per gram means that the total surface area of one gram of silica is 170 square meters.
Particle sizes range from 10nm to several hundred micrometers;
The properties vary, and the uses are also different.
