Introduction
Silica sand is one of the most common varieties of sand found in the world. It is used for a wide range of applications, and can be purchased from various suppliers throughout the world. Silica sand is used in industrial processing, to make glass, as fill, and to create molds and castings.
High purity quartz sand by the unique physical and chemical properties, making it in the aviation, aerospace, electronic, mechanical, and the rapid development of today's IT industry occupies a pivotal position, in particular its intrinsic molecular chain structure, the crystal shape and lattice variation, it has a high temperature, thermal expansion coefficient is small, highly insulated, corrosion resistance, the piezoelectric effect, resonance effect and its unique optical properties, in many high-tech products is playing an increasingly
