The general production route of Precipitation silica (silica) is :first, under using of fuel or gas at high temperatures, quartz sand and soda ash react with sodium silicate，sodium silicate prepared into a certain concentration of dilute solution, and then under certain conditions to add a certain acid, so that silica precipitation, and then by washing, filtration, drying, crushing,at last the product of white carbon black is produced. The main method of producing silica are:precipitation method ,sub-acid method, sol method, carbonization and many other specific methods, we mainly use acid method. Acid method is the soluble silicate and sulfuric acid (or other acid) together, when the reaction reaches a certain pH value to stop adding acid reaction, aging, and then filter and repeatedly washed with water, remove Na2SO4, Send dry, crushed to get the product.
