玻璃和石英玻璃的化学成分都是以二氧化硅为主。玻璃中的二氧化硅通常是一个硅原子和四个氧原子结合成四面体。每个二氧化硅四面体通过硅氧键形成一个三维网络，这样由硅和氧原子形成一个不规则的六元环。石英玻璃由于Si-O-Si之间的角度易于变动而具有柔性，这种环状结构相对稳定。根据硅氧键角大小不同而形成不同的同分异构体。石英玻璃的硅氧夹角为150o，是一种简单的玻璃。通常人们称它为石英。它具有高度交联的三维结构，因此它的熔点高（近2000℃），热膨胀系数低。它的成分主要是二氧化硅，含有极少的金属氧化物，抗化学腐蚀性好和抗张强度高.具有化学惰性，热稳定性好，内表面光滑易润湿。

The chemical composition of glass and quartz glass is mainly silica. Silica in glass is usually one silicon atom combined with four oxygen atoms in a tetrahedron. Each silica tetrahedron forms a three-dimensional network through silicon-oxygen bonds, such that silicon and oxygen atoms form an irregular six-membered ring. Quartz glass is flexible because the angle between Si-O-Si is easy to change, and this ring structure is relatively stable. Different ***mers are formed according to the size of the silicon-oxygen bond angle. Quartz glass has a silicon-oxygen angle of 150o, which is the simplest glass. Usually people call it quartz. It has a highly cross-linked three-dimensional structure, so it has a high melting point (nearly 2000°C) and a low coefficient of thermal expansion. It is mainly composed of silicon dioxide, contains very few metal oxides, has good chemical corrosion resistance and high tensile strength. It has chemical inertness, good thermal stability, and the inner surface is smooth and easy to wet.
