Construction silica sand Introduction

Construction quartz sand is quartz stone processed by the crushing of quartz particles. Quartz stone is a non-metallic mineral, a hard, wearable, chemical properties and stability of silicate minerals, the main mineral composition is SiO2. Quartz sand is an important industrial mineral raw materials, non-chemical dangerous goods, widely used in glass, casting, ceramics and fireproof materials, smelting ferrosilicon, metallurgical flux, metallurgy, construction, chemical, plastics, rubber, abrasive, filter and other industries.
