石英(Quartz)

        石英是一种由二氧化硅组成的矿物，无色透明，常含有少量杂质成分，而变为半透明或不透明的晶体，质地坚硬，莫氏硬度为 7，化学稳定性强，是重要的工业矿物原料，广泛应用于玻璃、陶瓷、电子、光学等领域。

Quartz is a mineral composed of silicon dioxide. It is colorless and transparent, but often contains a small amount of impurity components, which makes it turn into a translucent or opaque crystal. It has a hard texture, with a Mohs hardness of 7, and strong chemical stability. Quartz is an important industrial mineral raw material and is widely used in fields such as glass, ceramics, electronics, and optics.
