| toxicity | can stimulate the skin, mucous membranes and eyes, and produce hydrogen chloride toxic smoke when exposed to water. The maximum allowable concentration (in Ge) is 1mg/m3. At the same time, the content of hydrogen chloride in the air should be controlled. Production workers should wear gas masks, work clothes, latex gloves and other labor protection articles to protect the skin and eyes. Production equipment should be sealed to prevent the leakage of steam and smoke. The workshop should be well ventilated. |
| Use | raw materials for the preparation of semiconductor germanium. Optical fiber dopant. used as raw material for semiconductor germanium |
| production method | germanium dioxide hydrochloric acid method germanium dioxide is added to a reactor with a reflux condenser, the reaction was carried out by adding hydrochloric acid Dropwise while heating, and germanium tetrachloride liquid was generated. The finished product of germanium tetrachloride was obtained by distillation and condensation. Its GeO2 4HCl → gesl4 2H2O synthesis method metal germanium is added into the reactor and chlorine gas is introduced into the reactor for chlorination reaction at 250 ℃ to generate germanium tetrachloride, which is cooled to -20 ℃ and subjected to rectification and condensation, finished germanium tetrachloride was obtained. Ge 2C12 → gesl4 |
