How to synthesize 100 nm sized silica?
Water spray drying method is often used in inorganic coated with nano titanium dioxide, which is deposited on the TiO2 surface with a layer of oxide or hydrous metal oxides, to reduce its chemical activity, improve the weatherability of ridicule. Therefore, adding silica can solve the above shortcomings.
TiO2 because of its activity is too large, easy to agglomerate, affect the performance of products, the commonly used methods are aqueous solution deposition drying method, sol-gel method, etc..
