Unique "Three-Dimensional Dendritic" Structure of Fumed Silica Powder

The "primary particle" in the reaction furnace with the direction of the flame continues to move forward, the particles collide with each other, at this time, because the temperature in the reaction furnace is still relatively high, the particles are still close to the molten state, the particles collide and fuse together, forming a three-dimensional dendritic structure of multiple spherical particles fused together, known as the silica "Aggregate Particle". Since the particles in the aggregates are fused together, they are stable structures that are almost impossible to separate.
