Description
The inherent molecular chain structure, crystal shape and lattice change rule of silicon sand make it have high temperature resistance, small thermal expansion coefficient, high insulation, corrosion resistance, piezoelectric effect, resonance effect and its unique optical characteristics, which are used in many high-tech products. Silicon sand lays an increasingly important role.
