The difference between quartz sand and silica

Quartz sand is a more general term. It can be divided into different qualities according to different colors, component content and uses. We all know that the main component of quartz sand is silica, and the content of high-quality quartz sand is as high as 100%. More than ninety-six, but we strictly prohibit the export of quartz sand, but silica can be exported, which caused many people to misunderstand. Today I will summarize the main differences between quartz sand and silica.

Quartz sand is a kind of non-metallic mineral, with a relatively hard texture, abrasion-resistant surface, and relatively stable chemical properties. The main mineral component is silicon dioxide. The color is usually milky white or colorless and translucent. According to Li’s The hardness tester has a hardness of 7, which is an important industrial mineral raw material. Quartz sand appears in industries such as glass, ceramics, and metallurgy.

Silica, the main component of quartz sand, is a compound composed of oxygen and silicon. It is a pure chemical substance. It has similar properties to quartz sand. It is non-toxic, non-combustible, non-corrosive, and is not a tube. For products, if the exported item is quartz sand, but it is declared as silica or glass raw material, you will need to pay the corresponding price. The customs has a database and comparison pictures. Therefore, do not violate the law.
