高纯氢

High Pure Hydrogen


产品介绍 Product introduction

        高纯氢（H2）是一种无色无臭的可燃气体，在空气中的可燃极限为4.1%~74.1%（体积浓度），其自燃温度为571.2℃，沸点为-252.8℃，熔点为-259.2℃。常温下，氢气的性质很稳定，不容易跟其它物质发生化学反应。高纯氢在电子微芯片等行业中有着非常重要的应用，在一些电子材料的生长与衬底的制备、氧化工艺、外延工艺以及化学气相沉积技术中，均采用氢气作为反应气、还原气或保护气。
High pure hydrogen (H2) is a kind of colorless, odorless combustible gas withflammability limit in the air of 4.1% ~ 74.1% (volume concentration), its autoignition temperature is 571.2℃, boiling point is 252.8℃, melting point is 259.2℃. Hydrogen is stable at room temperature, and it is not easy to react with other substances. High purity hydrogen has a very important application in electronic microchip and other industries. Hydrogen is used as reaction gas, reduction gas or protective gasduring the oxidation process, epitaxy process and chemical vapor deposition (CVD) technology of some electronic materials.
