Germanium tetrachloride, or GeCl4, plays a vital role in the manufacture of purified germanium dioxide and germanium metal. These compounds are later used in a variety of applications, including fiber optic production, camera lens, microscopy, and electronic applications.

In this article, we explore the process of formation of purified germanium dioxide and germanium metal and how Germanium tetrachloride is used in fiber optic production.

Obtaining GeCl4 from Sphalerite Zinc Ore and Copper Ore

Sphalerite zinc ore and copper ore are primary sources of germanium. They contain small amounts of germanium that need to be extracted and purified.

Initially, the ore is processed through flotation or gravity concentration to obtain pure zinc, copper, and lead concentrates. Once the concentrates are obtained, the concentrates then go through a series of steps to extract germanium.

In the first step, the concentrates are oxidized, and the ores go through a leaching process to dissolve the germanium present in the ore. The leaching of germanium containing copper ores is done using a sulfuric acid solution, whereas zinc ores are leached using hot sodium hydroxide.

The leaching process separates germanium and leaves behind iron, aluminum, and other impurities.

Chlorination and Distillation Process

Once the germanium is extracted from the ore, the focus turns to purification. The chlorination and distillation processes are used to separate germanium from other elements and purify it.

The process involves the reaction of either GeO2 or purified Ge with chlorine gas to obtain GeCl4. The chlorination reaction is carried out at high temperatures, around 700C, and atmospheric pressure.

After the reaction, the GeCl4 gas is cooled before it undergoes a distillation process. Distillation is the process of separating various components present in a liquid mixture based on their boiling point.

Germanium tetrachloride has a boiling point of 83.6C, which makes it easy to separate from other impurities present in the reaction mixture. The purified GeCl4 is then kept in a storage tank for later use.

Formation of High-Purity Germanium Metal

The next step in the process of forming purified germanium dioxide and germanium metal is the formation of high-purity germanium metal. The GeCl4 obtained from the chlorination and distillation process is reacted with hydrogen at high temperatures, around 1000C, to produce germanium metal.

The reaction is exothermic and is carried out in a closed reactor to reduce the risk of contamination. By reacting the purified Germanium tetrachloride with hydrogen, high-purity germanium metal is obtained.

Fiber Optic Production
