東西電子/4000A/4016A各種型號的玻璃柱 詳細信息：

玻璃中的二氧化硅通常是一個硅原子和四個氧原子結(jié)合成四面體。每個二氧化硅四面體通過硅氧鍵形成一個三維網(wǎng)絡(luò)，這樣由硅和氧原子形成一個不規(guī)則的六元環(huán)。石英玻璃由于Si-O-Si之間的角度易于變動而具有柔性，這種環(huán)狀結(jié)構(gòu)相對穩(wěn)定。它具有高度交聯(lián)的三維結(jié)構(gòu)，因此它的熔點高（近2000℃），熱膨脹系數(shù)低。它的成分主要是二氧化硅，含有極少的金屬氧化物，抗化學(xué)腐蝕性好和抗張強度高.具有化學(xué)惰性，熱穩(wěn)定性好，內(nèi)表面光滑易潤濕。

Dongxi Electronics/4000A/4016A various types of glass columns Details:

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. 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.
