All you want to know about the surface modification of quartz sand powder is from the manufacturer of modified silicon micro powder

Mechanical grinding and chemical coating modification of quartz sand refer to the addition of modifiers during mechanical force, fine grinding, and ultrafine grinding processes. 

As the particle size of quartz sand powder decreases, surface modification of its particles is carried out.

The characteristic of this composite modification process is that the process is relatively simple. Some modifiers also have a grinding aid effect, which can improve the crushing efficiency. 

However, its temperature is difficult to control, and the particles are constantly crushed, producing new surfaces. The coating of the modifier is difficult to be uniform. In addition, the grinding 

equipment produces local high temperature in the process of strong mechanical force, which causes partial modifier decomposition or molecular structure destruction
